“You’ve got to think about big things while you’re doing small things,
 so that all the small things go in the right direction.” — Alvin Toffler
I
n 1980, Alvin Toffler published a bestseller called The Third Wave. He described
three historic phases in which civilization has developed. The first was the
agricultural transition from a hunter-gatherer structure. The second was the
industrial age, largely driven by the burning of cheap fossil fuels like coal and
petroleum. The third is the information age, where we connect to the internet
using our smartphones in a process that is highly dependent on base metals.
We know now that the drivers of our prosperity have brought us to our current
situation. When we think about Toffler’s quote today, the “big thing” is climate
change. The “small things” are what we do to move towards resiliency and future
proofing our homes.
This is our annual future proofing issue. Inside, you’ll find information and tips
on future proofing (the process of anticipating the future and developing methods
to minimize the effects of future events) and resiliency (the capacity to recover
quickly from difficulty).
The Ontario Building Code package A1 reference house only requires 28 KBtu
per hour on the coldest day of the year, but this load is too small for most furnaces.
Our feature article on iGEN Technologies (page 16) explores a combination heating
system that provides heat and hot water. It can power itself through a blackout in a
winter storm by generating electricity. Dugald Wells from Marshall Homes is test
driving this technology in his own cottage for potential use in a project in Pickering.
In a now-repealed Code change, electric vehicle charging stations had been
required to be roughed in. Lou Bada explains why he supports the repeal on page 3.
In “Ready, Set, Charge!” (page 28), we profile eCAMION, a Scarborough company
that knows bigger batteries in cars require new technology for rapid charging.
Alice Wang explains how they are working toward a network of high-tech rapid
charging stations.
In “Resilient Construction” (page 5), Gord Cooke talks about resiliency
planning for builders and how it can help us with a more demanding climate.
Additionally, Doug Tarry reviews five significant ways we can reduce our carbon
footprint (page 30).
The third wave requires that we think differently, and collectively, about clean
prosperity. The Sustainable Housing Foundation (SHF) brings together thought
leaders, builders and manufacturers to create an informed path forward. You can
find a recap of the recent Sustainable Housing Foundation Dinner on page 13.
It seems fitting to quote Toffler again for his views of future success: “The
illiterate of the future will not be those who cannot read and write but those who
cannot learn, unlearn and relearn. If you do not have a strategy, you’re part of
someone else’s strategy.” Ask yourself: Is your strategy stuck in the second wave or
is it moving forward in the third wave? BB

Building Resiliency and
Future Proofing Our Homes

BETTERBUILDER.CA | ISSUE 32 | WINTER 2019
O
ntario’s current Ministry
of Municipal Affairs and
Housing moved quickly in
its mandate to repeal regulations
in the Ontario Building Code
requiring the rough-in of car
charging stations in Part 9 buildings
(low-rise) and suspended plans to
implement them in larger buildings.
This was met with great relief
within our industry, but not for
the reasons you might think. Cost
implications are not the only thing
on builders’ minds: we are more
concerned with the implementation
and the value proposition of new
regulations for our customers.
Although the policy to further
“green-up” new homes through
regulations is a no-brainer for any
government looking to score cheap
political points, putting the cart
before the horse (or the charger before
the electric vehicle [EV], as the case
may be) ultimately creates bad policy.
Here’s why.
Many in our industry were quick
to point out that requirements for car
charger rough-ins were problematic
and not well thought out. Our industry
indicated we were willing to work on
more rational solutions in order to
achieve the goal of curbing carbon
emissions. However, in expressing
our concerns, we were often labelled
as uninspired (or worse). The pitfalls,
unworkability and ineffectiveness
of the requirements mattered little
to the policy makers as long as
they could be seen to be doing the
right thing. Although the goal of
electrifying everything from housing
to transportation seems like a good
idea from 10,000 feet (given Ontario’s
relatively low-carbon electrical
generation system), builders have to
build with their feet on the ground.
When we examined Ontario’s
microFIT program and reverse
metering with photovoltaic solar
panels, we quickly found out that the
electrical grid was not always ready
for a mass uptake of the new program.
The infrastructure and utilities were
often inadequate and unprepared.
Similarly, when speaking to the local
distribution companies (LDCs) about
car charging stations, it appeared
that our grid wouldn’t be ready for a
mass uptake. If many people come
home at the end of a work day, plug
in their EVs and turn on the stove to
cook dinner all at the same time, our
electrical distribution system would be
overwhelmed. However, builders were
being compelled to put car charger
rough-ins into thousands of new
homes every year.
It is not solely the problem of overall
capacity of the electrical system: it’s
the peak capacity of the system and
infrastructure that matters more. “Peak
shaving” and trying to match capacity
and demand is the more salient issue
for the LDCs. Utility scale energy
storage systems are not adequately
installed on Ontario’s energy grid.
If we had to rough-in anything in
a home, I believe it would be better to
rough-in for home battery storage. A
home battery could be charged off-
peak and discharged on-peak. It could
also charge a car while discharging
on-peak. It would help the electrical
grid “load-shift” and reduce the use
of natural gas-fired “peaker plants.”
A home storage battery could also
provide some relief in the case of
a blackout, which would also be a
strategy for building in a measure of
climate resilience. As the technology
evolves and improves, battery prices
will go down and electrical prices will
go up. By using a home storage battery,
home owners could realize the value
proposition of storing electricity at
home and take advantage of time-
of-use rates. It would also be a step
towards a distributed energy system.
Following the argument above, you
may ask: “Wouldn’t you still need a
car charger and rough-in for a home?”
Not necessarily. Firstly, we need to
distinguish the level of charging most
drivers will require. Builders were
3

thebadatest / LOU BADA
‘Charging’ Ahead
with Electric Vehicles
BETTERBUILDER.CA | ISSUE 32 | WINTER 20194
being asked to provide a rough-in for
a 240-volt, 30-amp level 2 charger,
which can charge an EV to travel
about a 290-kilometre range over an
eight-hour charge. A car charging
unit and installation would have to
be purchased by the home owner at
significant additional costs. If, on the
other hand, a purchaser wanted a level
1 charge, a regular 120-volt plug would
suffice and give an EV a 65-kilometre
range over an eight-hour charge. In
this case, our rough-in would be a
waste of material and money.
According to Statistics Canada’s
Journey to Work: Key Results from
the 2016 Census survey, the median
distance travelled to work for those
who worked outside the home (6%
work from home) was 8.7 kilometres
(9.6 kilometres in Toronto). In Canada,
12.4% of people take public transit; in
the Greater Toronto Area, that number
doubles to nearly 25%. About 6.9% in
urban areas walk or bike to work.
If I were investigating the purchase
of a new car, I would seriously look at a
plug-in hybrid (PHEV), which has both
an all-electric operating mode and
a conventional gas engine operating
mode (used after the battery has been
fully discharged). There are a number
of affordable PHEVs that can travel
about 45 kilometres on an eight-hour,
level 1 charge. I believe it would be
perfectly adequate for most people,
based on the Statistics Canada’s survey.
A PHEV would also work better for those
living in rural areas (who may need to
drive further, more often) or drivers
occasionally taking a long road trip.
In light of this, why would we be
mandated to install rough-ins for level
2 charging stations (with the requisite
200-amp service) in every new home
today and in the foreseeable future,
when someone could use a level 1
charger for their daily commute to
work and back? New technology and
level 3 chargers on a commercial
basis are also evolving quickly and
becoming more commonplace. At the
time the requirements were in effect, I
really believed that we were wastefully
stranding a lot of infrastructure inside
our houses for no good reason.
Someday, driverless cars may make
an appearance and upset the apple
cart altogether. If that day comes,
hopefully the horse will be pulling the
cart and not vice versa. BB

A
t the time of writing this
article work is being
completed on a new family
cottage for my brothers and I and
our growing extended families.
The cottage is on the eastern shores
of Lake Huron in Southampton,
Ontario which means we will see the
most beautiful sunsets unfold from
the balcony all summer long and
experience the wrath of relentless
westerly winds howling across
80 kilometers of icy waters from
Michigan all winter long.
Regular readers of this magazine
will recall we completed a modest Net
Zero cottage in Southampton 4 years
ago. Derek Seaman of Seaman and
Sons Builders was so great to work
with on that project, it was obvious
we would be working with him again.
That 2015 project was on a small infill
lot 2 streets back from the shore and
Derek was very quick to point out that
building right on the shore had very
different, exaggerated challenges. For
that reason, while it was a given that
we would be building again to the
Canadian Home Builders Association
Net Zero Labelling Program, we
decided to add the theme of resilient
construction to the project.
As climate change and sustain­
ability permeates most every
industry, a rather obvious response
by the building industry would be,
of course, to build ever more energy
efficient homes. Perhaps, though,
a more compelling story is to focus
on the lasting legacy of the homes
you build. I have the great pleasure
of working with hundreds of builders
across North America each year and
I can say with complete confidence
that every one of them takes pride in
knowing that, unlike virtually any
other consumer product, the projects
they build will provide comfort and
safety for generations of families.
Homes designed to better handle the
extremes of what ever Mother Nature
has in store has been a consistent
theme of every housing conference I
have been to over the last 2 years.
It will be no surprise that the
specifics of the conversation always
relate to the imminent risks of the
region I happen to be in. In BC it’s
about fire and seismic resiliency with
the added challenge in coastal regions
of months of rain with little time
for drying. In California, the recent
images of devastating wild fires fuelled
by parched winds are driving design
and construction decisions. In Texas
and the Southeast of the US, right up
into the Maritimes the conversations
are about flooding and severe wind
driven rain. In the Midwest, including
our prairie provinces more frequent
and more severe tornados dominant
new design objectives.
Thus, when we enlisted architect
Mark Rosen of Building Energy Inc
in Ottawa to design the project we
asked him to consider the goal of a
family cottage that should be enjoyed
for generations to come and the
5

climate challenges most likely to
affect a lakefront property in south
western Ontario. Let me share just a
few of those considerations and the
decisions that followed, some that are
simple and obvious and others that
require changes to Derek’s normal
build process.
It started with the decision to
build fully slab on grade, even though
it might be normal to think of the
extra living space that a basement
would afford the extended family.
The decision seemed vindicated
even during the build as neighbours
up and down the shore had to
mobilize to clean up and dry out
flooded basements due to one those
seemingly more frequent harsh storms.
That slab was protected by the 20 mil
thick gas barrier called Radon Block
that provides both superior moisture
management and soil gas protection.
The entire slab assembly shown in
the picture here included the Radon
Guard foam block that provides R10
insulation value while creating a vent
space. This can be used to eliminate
the need for the typical crushed stone
under a slab. All together we ended up
with approximately R28 under the slab,
included the top layer of the AMPEX
foam that allows for quick and effective
installation of in-floor heating pipe.

old first Net Zero cottage we built,

unless there is a code change. I would
encourage all readers of this magazine
who are clearly interested, as indicated
by the title of the magazine, in the
continual improvement of new homes
to start including tie-down straps or
strategies on every project. Then put
a sample of these simple pieces of
metal in the hands of every one of your
salespeople. Let them know this is one
of the most cost effective things any
caring builder can do to ensure the
resiliency of homes in the face of ever
more severe storms. BB

we used a pretty standard 2x6 wall
with exterior XPS foam insulation.
In this project we felt an insulated
concrete form structure provided
the generational durability we were
looking for. I was very pleased that at
least one ICF manufacture, Amvic,
has invested in the tooling to get to
higher effective R-values than the
typical industry R22. In this case
we used their ICF-R30 product. This
allowed us to get to the levels of wall
insulation needed to achieve Net
Zero with out adding supplemental
insulation and still benefit from the
inherent air tightness, thermal mass
and climate resistance of a concrete
structure. Winter power outages are
pretty common in this windy area
and it’s comforting for the family to
know that the house will be freeze-
protected for weeks at a time.
Mark, the architect, envisioned
the use a natural stone façade from
a local quarry to create a protective
boundary between the lake and
the house. Drifting sand and wind
driven rain always affect houses on
this shoreline. With the water level
up to historically high levels this
year, up over 12 just this year over
last, it is nice to have this feeling of
safety, especially since it gives such a
beautiful look as well.
The prevailing architectural
look on the lakefront in this area is a
lapped wood siding and Mark wanted
to retain that history even though
painted wood takes a beating off the
wind swept sand beaches. That look
though is preserved with the use of
a far more durable engineered wood
siding product. In this case, the pre-
treated substrate from LPs Smart
Side format has a 50-year warranty
and the paint coating is specifically
engineered for the Canadian climate.
I was particularly pleased that Derek
always installs siding over strapping
to ensure the optimized drainage and
drying of a true rainscreen, backed up
the DuPont Tyvek water management
system.
Although there are many other
details that will ensure the resiliency
of this family project that I hope to
outline in future articles, there is
one last one I want to mention in this
article. There has been talk in the
industry of our code being updated to
include wind resistant elements that
are common throughout the US. One
example is the interest in roof tie-
downs, often referred to as hurricane
straps. The Institute for Catastrophic
Loss Reduction (ICLR), established by
a segment of the insurance industry
and affiliated with the University of
Western Ontario has been sponsoring
research and submitting code requests
for roof tie-down strategies. It is one
of those low cost items that can be so
quickly overlooked in construction and
thus seldom implemented by builders

industrynews / PAUL DE BERARDIS
If builders’ initiatives support the
goals of government policy, we firmly
believe they should be rewarded
through some type of monetary
incentive or carbon tax break for
reducing carbon emissions in the
homes they build. There are currently
numerous different types of rebates
and incentives that exist for auto
manufacturers and car buyers in
relation to hybrid and/or electric
vehicles. And there are energy-efficient
renovation rebates and tax credits
that exist for home owners who try to
improve the energy efficiency of their
existing residences. As a matter of
fact, the City of Toronto just launched
their BetterHomesTO program to
provide rebates and incentives for
home owners and renters.
However, once again, there’s
nothing for builders and new-home
buyers looking to ease the financial
burden of building and buying a
high-performance home. In terms
of value for money, it is obviously
much simpler and more cost efficient
to construct energy-efficient homes
from the get-go – especially since
some components, like a wall
assembly, are difficult to upgrade
after the fact. Why not offer incentives
for future-built homes rather than
solely for existing homes, which face a
much more costly and uphill battle to
be retrofitted for energy efficiency?
Look: we all know regulations
continue to come down the pipeline
to reduce GHG emissions from new
homes. This is a highly regulated
industry that becomes an easy target
for rigorous performance mandates
on new homes through mechanisms
like the National Building Code (NBC)
and Ontario Building Code (OBC),
which up the ante on energy efficiency
with every iteration. In addition,
there are other municipal or regional
government requirements – such as
green standards, community energy
plans or even energy mandates within
subdivision agreements – that thrust
additional beyond-Code measures
onto new-home builders. The challenge
for the home-building industry and
their clients (new-home buyers) is
that various levels of government
are addressing their climate-change
reduction targets through lowering
GHG emissions on the backs of new-
home buyers, further exacerbating
housing affordability concerns.
So how can builders soften both
their own financial blow and the
added costs borne by new-home
buyers when it comes to improving
energy efficiency and lowering GHG
emissions? A framework needs to be
created for home builders exceeding
Code requirements and buyers alike
to tap into the many tax breaks and
rebates already offered to existing
home owners (which seem to generally
have little uptake).
After all, we’re building houses that
will be in operation for the next 75 to
100 years. The government needs to
devise a means to incentivize more
low-carbon new builds, without
further financially burdening
builders and home buyers. Under
the federal carbon tax regime, many
manufactured building products and
materials will cost more for builders,
who will then need to recoup those
added costs from home buyers.
Material costs for products such as
concrete, insulation and masonry
cladding will rise. We’re not knocking
the carbon tax per se, but some of
the funds generated from carbon
taxation could possibly be directed
to incentivizing high-performance
homes – hence the GHGST concept.
Let’s compare the home-building
industry to the auto industry. There
is a federal rebate (as well as various
provincial rebates) for electric and
hybrid vehicle purchasers, and these
rebates are ultimately funded by
Incentivize Green Construction
and Builders Will Build It
The government needs
to devise a means to
incentivize more low-
carbon new builds,
without further financially
burdening builders
and home buyers.
H
ave you ever thought about the greenhouse gas sales tax (GHGST)? Of
course you haven’t. We made it up.
But bear with us: what if this concept, the GHGST, was created to give
the federal government (or even the provincial government) a revenue mechanism
to incentivize home buyers to opt for new homes built with green building
practices and technologies? And then, through a fully realized green program,
builders could be given financial incentives to deliver this type of product.
BETTERBUILDER.CA | ISSUE 32 | WINTER 201910
taxpayers – yet this analogy eludes
governments when it comes to the
new-home building market. To me,
it seems like a win-win scenario,
where housing affordability concerns
and climate change woes can be
addressed through the same green
building incentivization policy.
Through this same program – and
bear with us, we’re throwing out ideas
here – let’s set the table for builders and
home owners to share in some type
of carbon tax credit, tax break, rebate
or whatever other creative policy
mechanism to reward exceptional
green building practices.
Our friend, Better Builder publisher
John Godden of Clearsphere, was
involved in rating 1,523 homes last
year built to standards beyond the
OBC. There are five builders shown in
the chart below. They deserve more
credit for reducing carbon because
they produced 15% less CO2 emissions

than other builders in other provinces
who build strictly to NBC. When we
benchmark these builders’ homes
built in 2019 compared to the NBC
emissions, the chart shows how many
cars they took off the road by building
houses that were 30% more efficient.
These five builders’ homes have
taken 475 cars off the road per year in
perpetuity (think five tonnes of CO2
per car against reductions).
While that makes a difference,
we have to be vocal and engage with
government so they can understand
and also support what our industry
is doing to make a difference. In fact,
there is more potential to making
houses greener than cars because
of their vastly longer lifespan – you
can get maybe 10 to 15 years out of a
brand new car before it is replaced or
scrapped, whereas a home has a useful
service life of at least 75 years. You
tell me: where is there more bang for
your buck when it comes to reducing
emissions?
So we’re suggesting various levels of
government engage with the building
industry to support and incentivize
low-carbon, new-home building.
Sure, the government can continue
gradually raising the bar simply
through increasing regulation – but to
truly get builders and home buyers on
board in a meaningful way, they need
the financial support to bring high-
performance building to the masses. A
high-performance green home should
get incentives: the buyer needs an
incentive to buy it, but the builder also
needs incentives to build it so that it’s
still financially accessible to consumers.
Everyone loves Tesla as a disruptive
game-changer – so why can’t we do the
same with high-performance green
homes? Where will that Tesla be in 100
years – when today’s new homes are
still standing, while contributing less
and less to greenhouse gases?
Let’s give the GHGST concept some
serious consideration. BB

M
ichael Bernstein is no
stranger to party politics –
and he’s heard pretty much
every question there is about carbon
tax. He believes that the carbon tax
is the best action to lower costs while
spurring innovation in the economy.
And he’s not alone in that view, either
– he points out that putting a price on
carbon use is widely considered as
the most affordable way of reducing
carbon while staying profitable.
The 30-something director of
Canadians for Clean Prosperity has
plenty of experience in this area. He
has an economics degree from Yale
and a master’s in public administra­
tion from Harvard, plus practical
experience as director of two profitable
organic food delivery companies
(Mama Earth and Farms  Forks).
Speaking at a recent Sustainable
Housing Foundation dinner, he says
he tries “to walk people through the
logic of carbon tax, why it’s needed
and why it should not be a partisan
issue.” Although the provincial and
federal Conservatives are in favour of
eliminating the carbon tax, Bernstein
observes that the tax doesn’t have to
run counter to conservative values:
“Preston Manning, for example,
is in favour [of carbon pricing].
Mark Cameron, senior policy
advisor to [Stephen] Harper, is in
favour. Conservatives have led on
environmental issues in the past –
like Brian Mulroney, who made an
impact on the environment by taking

important steps on acid rain. At the
end of the day, though, this should not
be a partisan issue.”
While he agrees with a more
conservative/less interventionist
perspective, he notes that “if you
want to address climate change,
there are only two ways to go about it:
[either] set a price on carbon pollution
and let business owners figure out
how to work around that, or have
government step in and dictate how
to reduce emissions.”
It would be fair to say that the 85
people who attended the event were
committed to greener construction
practices. Even so, Bernstein says
there were lots of questions about
carbon pricing and varying view­
points on the policy. He explains that
“the money goes back to you first, and
then you decide what you want to do:
pay higher prices on what you used to
pay, or save money by purchasing
things that are not manufactured by
those who pollute. It’s like finding a
$20 bill on the sidewalk. The money
is there; the choice is yours whether
you’ll pay up for something that
pollutes or save the money.”
How it affects business – and
builders – is a question he gets a
lot. The answer is that the federal
government has compensation
programs around energy efficiency.
He points specifically to two
programs that provide grants of up to
50% on home retrofits and new energy
equipment, like HVAC and boilers.
Bernstein argues the programs
“should stimulate some new
construction demand. These funds
comprise about 7% of the total carbon
tax revenue.”
But the biggest possible benefit to
builders is “avoiding the economic
consequences that come with a
warming climate, something the Bank
of Canada (BOC) has warned is a major
threat to the Canadian economy. In
fact, the BOC sees investors pulling
out if a company doesn’t have a
sustainability plan in place. This
affects the economy directly.”
While net zero is technically feasi­
ble through the use of more efficient
envelopes and mechanical systems, it
would add substantial costs to build­
ing. But Bernstein expects that will
change “since the pace of technologi­
cal innovation happens very fast. Take
the battery and solar panel industry
– the price has come down a lot, and
home owners are very interested.”
Growth spurs more growth – and
with the rapid rise of the clean tech
sector, ever more energy-efficient
products are coming to market.
The demand for green building will
continue as buyers become more
informed, and wise builders will
prepare now to capitalize on that,
Bernstein says. Tridel, for example,
is currently piloting CarbonCure
concrete products in their buildings.
“Consumers are increasingly going
to look for, and even expect, these
things when they set out to purchase
a home. If you build homes that are
ready for an EV [which had been part
of the Ontario Building Code until
the provincial government recently
rescinded it], for example ... consumers
will be appreciative,” Bernstein
says. He adds that builders who are
on the cutting edge of low-carbon
construction should be able to export
their knowledge to other jurisdictions.
Although the Doug Ford
government has put the carbon tax on
the shelf for the time being, Bernstein
argues that the carbon tax is inevitable.
China has now put carbon pricing in
place, and the US has carbon pricing
on a third of its economy. “From a
business perspective, the world is
moving to a cleaner economy, which
means renewable energy and products
will be at a premium. We should
capitalize on that now – because if we
delay, we’ll miss the opportunity and
ultimately our economy will suffer.”
Sixteen-year-old Greta Thunberg
has shown the importance of climate
change activism around the world,
including in Canada. Nevertheless,
Bernstein writes in a recent Maclean’s
article that “it’s also important for
[Canadians] to know that we don’t
all have to stop flying, swear off meat
or close down our heavy industry to
address climate change.” Instead, we
already have a much better solution:
an economy-wide carbon tax and
rebate. BB

are not manufactured by those who pollute.”

W
hen talking to people about his
company’s product, Alan Clarke
likes to say: “iGEN has solved a
problem that most people don’t even know they
have until it’s too late.”
The chief business strategy officer of six-person
iGEN Technologies (based out of Richmond Hill,
Ontario) is referring to a challenge many home
owners in Ontario have faced in recent years –
namely, power outages in cold weather.
The one essential thing you need to be func­
tional during a winter power outage is your furnace
– but given that it’s an appliance that requires two
power inputs (natural gas/propane and electricity),
when the lights go out, so does the heat.
It was this exact scenario that sparked an idea
for engineers Michael Chatzigrigoriou and Patrick
Lai, who suffered a lengthy power outage in the
wake of an ice storm in 2012. Clarke says that the
two HVAC consultants came to the conclusion that
“this is ridiculous; this is what we do for a living,
and we can’t heat our own homes.”
featurestory / ROB BLACKSTIEN
A small Richmond Hill company may have the next
big thing in home heating innovation on its hands.
The Heat IsOn
BETTERBUILDER.CA | ISSUE 32 | WINTER 2019
The pair determined that there had to be
a better way. They set about creating a self-
powered furnace, a concept that – when pre­
sented to the masses – elicits plenty of ‘why
didn’t I think of that?’ reactions, Clarke says.
Chatzigrigoriou and Lai spent about a
year building a prototype and, by 2013, what
would become the i2 was born. At this point,
the pair decided to devote themselves to
the project full-time in an effort to bring the
product to market.
Running Itself
The i2 uses natural gas or propane, converting
that energy into heat and enough electricity
to run not only itself when the power goes
out, but also a hot water heater, with enough
surplus to keep your modem running and your
cell phone charged.
The benefits the unit offers are plentiful,
including utility cost savings from a more
efficient heating appliance, environmental
benefits (given that the i2 results in lower
greenhouse gas emissions than traditional
heating appliances) and the peace of mind
that home heating won’t be affected by a
blackout or utility interruption.
While there was an early investor in the
company (who has since been bought out),
iGEN has been mostly self-financed and is now
100% owned by Chatzigrigoriou, Lai and the
team. Clarke says the company also received
grants from various government agencies and
industry associations and is currently engaged
in efforts to raise more equity to “fuel our
growth” – no pun intended.
The original concept for the i2 was a single
unit, but the box was extremely heavy and
large – about 50% wider than a traditional
furnace, meaning it couldn’t fit through
standard-sized doorways.
At this time (late 2017), the i2 was being
tested at three independent labs. Once the
performance data was verified, the next stage
was to streamline the product down to a more
manageable size.
The answer came in serendipitous form,
as UK-based competitor Flowgroup plc had
developed a product that operated on a similar
principle (a replacement for residential boilers
that generated an electricity stream that could
be sold back to the grid). The company was
running into some difficulties, so it wound up
disposing of the business unit.
iGEN pounced, taking Flowgroup’s inven­
tory of about 1,000 units off its hands and
gaining the rights to the worldwide patents
and intellectual property.

Dugald Wells of Marshall Homes are testing
iGEN’s i2 units in Wells’s new cottage.
BETTERBUILDER.CA | ISSUE 32 | WINTER 201918
Solving Issues
This solved a couple of issues for iGEN.
First, they were able to overcome the
challenge of how to separate the heat
and electricity generation from the
heat distribution in the home. Second,
by breaking the solution into two
pieces, the size issue was resolved.
Now, there’s a wall-hung piece
(the boiler unit and vapour expansion
cycle module, which generates the
heat and electricity) and a floor unit
that replaces the furnace, which
includes a heat exchanger with a
blower fan. Heat is transferred from
the boiler unit to the heat exchanger
with a hot water loop.
While the i2 uses the same
ductwork as existing gas furnaces,
Clarke explains that the installation
process is a bit different, but
traditional furnace installers should
have no issues mastering it.
Still, the product is so unique
that gaining certification for selling
the i2 in North America has proved
challenging because, Clarke explains,
no standard currently exists for self-
powered appliances. In fact, iGEN is
working with the Standards Council of
Canada to develop a standard for this
product, something it hopes is com­
pleted later this year or early in 2020.
In the meantime, iGEN has been
granted approval to run an early
adopter program – an initiative
that’s generated promising results,
including an estimated $1,863 utility
cost savings over a 10-year period in
a 1,500-square-foot home. The case
study numbers were provided by third-
party simulations, so they are merely
estimates, Clarke says. But he adds that
the company is heavily monitoring
these initial field installs to get a more
accurate sense of the annual savings.
Early Adopters
Clarke says the 44,000 BTU per
hour output i2 is ideal for homes
between 1,000 and 2,200 square feet,
depending on the house age, quality
of construction, tightness of envelope
and insulation quality.
According to Clarke, another 20 to
40 early adopter installs are planned
before the end of 2019, but none may be
more important than the i2 that’s being
tested in Dugald Wells’s new cottage.
That’s because this trial is not
simply for a customer, but possibly
a key business partner. Wells is the
general manager of Pickering-based
Marshall Homes, an innovator
in energy-efficient housing and a
company that’s keenly interested to see
if the i2 is ready for prime time.
Wells had been familiar with iGEN
for some time, thanks to his long
association (both professionally and
personally) with Clarke, who himself
first heard of iGEN while he was doing
consulting work for Marshall Homes.
In the walkout section of the
cottage, Wells had roughed in for
radiant floor heating, but was unsure
he was going to go that route given that
it would require a second boiler.
He says what really caught his
attention was when he heard about
iGEN’s acquisition of Flowgroup’s busi­
ness unit because, over in the UK, it’s
generally all hydronic heating, he says.
Wells’s goal was to tap off the iGEN’s
coil – the boiler in the UK version – to
take hot water to use in the radiant
flooring loop as well as for the forced
air, “because otherwise I would have to
buy a whole new furnace.”
Running the Numbers
Wells approached Clarke to find
out whether this would work. The
iGEN team went off, did a bunch of
calculations and determined that it
could in fact be done.
The i2 heating system installed and monitored in Coach House.

“So, with one unit, I am serving
both my radiant floor heating loop as
well as my forced air distribution,”
Wells says. This offers multiple
benefits, as his forced air system
will run less often, and the radiant
floor heating is more comfortable
than forced air. It will deliver more
even temperatures, greater energy
efficiency, more comfort and fewer
noise and temperature fluctuations
with the forced air going on and off.

When Wells test drives the i2 this
winter, it will be because Marshall
Homes is considering adding the unit
into the homes in an upcoming and
very unique new housing development.
Altona Towns, a 27-townhome project
in Pickering, “goes right to the heart
of how the electricity market works in
this province.”
This ambitious project is a window
into the future of housing, featuring
a community that will be powered by
a microgrid, thereby reducing both
utility bills and carbon footprint. It
features a solar array and a powerful
standalone battery made by Tesla.
The Tesla Powerpack is a fully
integrated energy storage system that
includes DC batteries, a bi-directional
inverter and a Powerpack controller
with intelligent software. It delivers
multiple applications, including peak
shaving, load shifting and emergency
backup.

THE MICROGRID AT ALTONA TOWNS
ORIGINALDIAGRAMCOURTESYMARSHALLHOMES
BETTERBUILDER.CA | ISSUE 32 | WINTER 201920
By being deemed a special demon­
stration project, Altona Towns was
able to barter an agreement with
utility company Elexicon and Opus
One (which creates grid control
software) so that – in the absence
of virtual net metering – the condo
corporation will be compensated for
all the power generated that becomes
available to the grid. The residents
will benefit from this through
reduced condo fees. Wells said
they had to come up with this plan
“because government policy is still in
the dinosaur age.”
Cogeneration
This brings us to the issue of cogener­
ation (or combined heat and power
(CHP)) and the possibilities it creates.
Currently, Wells says, it’s a one-way
street, in which the utility gives you
power and you give them money. So,
if you want to have your own power
generation or storage, you’re on your
own (with the exception of special
deals involving wind or solar farms).
CHP systems tend to be large-scale
grids, and micro CHPs are for small
communities. Clarke calls their system
“nano CHP” because it’s simply for the
appliance. “We’re not trying to power
the whole house; we’re just a better
heating plant,” Clarke says.
Wells will put that theory to the
test this winter as a trial run for much
bigger things. “We’re interested, but
... at the end of the day, we’ve got to
satisfy 27 home owners and we want to
make sure that equipment functions
as advertised,” he says. This will be
determined by his own findings, the
results from the other early adopters,
and how iGEN’s service and response
holds up should there be any issues.
If nothing else, Wells’s neighbours
are fascinated by his cottage plans. He
had a group of friends over and was
showing them the i2. Suddenly, Wells
was backed into a corner where a pile
of wood lay, surrounded by a transfixed
audience gathered in a semi circle. So,
he found himself on top of the wood
pile, lecturing about the technology as
they lobbed question after question at
him. Obviously, there’s interest in this.
Lots at Stake
And just as clearly, there’s a lot at stake
for iGEN over the next few months, but
Clarke is bullish. “Depending on how
well we are able to perform in Dugald’s
cottage this winter, I think if everything
goes as well as we expect it will, that
will make a stronger case for Marshall
Homes to include our units,” he says.
For Wells’s part, while he’s with­
holding judgment on the technology for
the time being, he’s already made up
his mind about the people behind the
i2. As an entrepreneur himself, he has
a good sense of what it takes to make it,
and he sees those qualities in iGEN.
“I’m really impressed with them.
They’re calm, they’re thoughtful.” The
fact that they’ve been at it for a few
years – with great personal sacrifice –
speaks to their commitment, he adds.
“They’re not a flash in the pan.”
Wells says if he were a Dragon’s
Den investor, he’d be quite interested
in iGEN: “I like what I see, but it’s early
days. They’ve got a lot to prove.”
The opportunity for iGEN to prove
it’s ready for prime time begins in
earnest now. BB

f there’s one thing you can do
with today’s buildings that makes
financial and environmental sense
for the future and is the number one
way of mitigating climate change, it
would be “improve your insulation,”
says Emma Smetaniuk, commercial
and residential sales representative
for ROCKWOOL™
.
That’s not just her opinion,
though – it’s also the opinion of the
International Renewable Energy
Agency (IRENA).
Smetaniuk never expected to work
in the construction materials industry
but, looking back, it all makes sense
now. Emma’s father was in the
construction business, as a framer,
for over 30 years. He was always a
fan of stone wool insulation when he
was building houses. After university
– Oswego in New York on a hockey
scholarship! – she returned to Canada
to work for Lafarge in their leadership
and development program. “It was a
fantastic opportunity; I got to grasp
multiple product lines and jobs within
the industry. I was very thankful
for the opportunity, especially the
mentorship,” she says.
But when the sales opportunity
arose at ROCKWOOL four years
later, Smetaniuk took to how the
company positively contributes to
our overall health and well-being.
The importance of what we do with
today’s buildings – and how we
move forward with newer builds and
renovations – essentially determines
the legacy we leave for future
generations. “ROCKWOOL is a leader
in high-performance and quality
stone wool insulation, and I wanted to
be part of it,” Smetaniuk explains.
ROCKWOOL’s particular
suitability to the task certainly makes
Smetaniuk’s job easier: “The product
has a massive list of qualities capable
of contributing to the fight against our
biggest environmental challenges.” She
starts with how durable, hydrophobic
and mould- and mildew-resistant
the product is. It’s also permeable,
breathable, fire resilient and energy
saving, and has dimensional stability,
she adds.
It can also take the heat,
thanks to a much higher
melting point than other
insulation. “You can literally
take a blow torch to it, and it
won’t burn. Actually, it can
withstand temperatures of up
to 1,177 °C,” Smetaniuk says.
“That’s important in residential
use, especially now that we’re
building homes much closer
together – duplexes, semis,
condos, multi-units and mid-
rise wood frame buildings.
Stone wool is non-combustible
and ideal to satisfy building
code requirements for zero
lot line applications. Even
detached homes are closer.”
Because ROCKWOOL is
hydro­phobic – that is, water
repellent – it’s effective when
there are compromises
in the building envelope,
Smetaniuk says. “The inorganic
composition makes ROCKWOOL
mould and mildew resistant,
so if condensation were to get
trapped in, it wouldn’t affect
the material. In addition, its
high vapour permeance maximizes
the drying potential if there is moisture
present in the wall assembly.”
As well, the thermal comfort it
provides can’t be underestimated.
Proper insulation can reduce a build­
ing’s heating needs by up to 70% by
helping to create an airtight building
envelope, along with proper air barrier
detailing. This seals out drafts so
interiors aren’t only more comfortable,
but cost less to heat and cool. “Due
to the product’s physical structure,

When Working with Builders
Emma Smetaniuk of ROCKWOOL.
BETTERBUILDER.CA | ISSUE 32 | WINTER 2019
density and thermal properties, ROCKWOOL
insulation saves energy by maintaining indoor
temperatures for all climates,” she notes.
The acoustic benefits also contribute to overall
well-being. When the party wall cavities between
duplexes or towns are filled with ROCKWOOL
insulation, you get quieter rooms on either side. That
works as well for schools and office buildings, which
makes for better learning and work environments.
ROCKWOOL batt insulation is friction fit and
prevents gaps, thus decreasing sound transmission
from room to room. Typical code party walls have
sound transmission class (STC) ratings of 53. Using
ROCKWOOL can yield an STC of up to 60.
Like any premium product, you pay a bit more for
it – but it pays huge dividends. For example, energy
efficiency is enhanced, energy costs are reduced
and overall indoor air quality is improved, as the
material has a GREENGUARD®
Gold certification.
This certification indicates lower product emissions
and actually garners LEED points.
The company has paired up with several
builders, including Cleary Homes, Absolute General
Contractors, Brookfield Residential, Empire TEETH
Homes and Doug Tarry Homes. The Tyendinaga
Mohawk Territory in Deseronto (near Quinte) is
using ROCKWOOL in a new fourplex, for which
Absolute General Contractors is hoping to achieve
LEED Gold certification. Emma’s competitive
hockey days taught her the importance of being a
team player. As such, she is very supportive in her
relationship to builders. A good example is Cleary
Homes, with whom ROCKWOOL worked on 30 homes
in the Orchard East Community in Bowmanville.
Cleary provided a finish-ready basement detail
consisting of Comfortboard™
(R-6) and Comfortbatt®
(R-14) on all 30 homes. Working with both Cleary
Homes and Absolute General Contractors was a real
honour because those companies saw the benefit of
such a sustainable product and how that contributes
to the overall health and well-being of the future
home owners.
Every project has different insulation needs,

depending on the type of home or
commercial building. ROCKWOOL
has been developing its Elite Builder
Program, which aims to educate
builders in determining which
products work best with their
projects. In fact, its building science
and technical support team provides
complimentary services to help
builders, architects and designers
find ways to increase their buildings’
energy efficiency.
The end goal, Smetaniuk says,
is to provide builders with the
tools required to construct high-
performance buildings that reduce
operating costs, enhance safety and
maximize occupant comfort. All these
factors enhance a builder’s brand
through home owner experience.
Three popular products comprise
the lion’s share of ROCKWOOL’s
residential line: ROCKWOOL
Comfortbatt®
, Safe’n’Sound®
and
Comfortboard™
. Comfortbatt®
is used
to insulate exterior walls, ceilings, ex-
posed floors, attics and basements,
to keep heat in and cold out and
deliver a top R-value to the home.
Safe’n’Sound®
adds fire protection
and sound damp­ening and is used
in interior walls and ceilings and
between floors.
Comfortboard™
is a rigid
insulation board that is denser than
our batts and is typically used above
and below grade as a continuous
insulation layer. It’s suitable for
both commercial and residential
applications, but it is especially
good in basements. In the fourplex
being constructed for the Mohawks
of the Bay of Quinte by Absolute
General Contractors, two inches
of Comfortboard™
was used in the
crawl space to thermally protect the
insulating concrete form (ICF) foam
foundation. The main exterior walls
and party walls are insulated with
Comfortbatt®
. Using ROCKWOOL
secures more points, which Absolute
General Contractors needs for a LEED
Gold certification.
Comfortboard™
was also used
in a recent research project run by
George Brown College, but initiated by
ROCKWOOL, Empire Communities,
Clearsphere and DuPont. The idea
was to install insulation into three
homes and monitor the results. George
Brown’s building science research
team monitored the assemblies,
evaluated the homes’ capacity for
handling heat and moisture, and
looked for ways to improve above-
and below-grade insulation to pass
on to Ontario builders. (See “TEETH
Checkup: A Look inside a Collaborative
Research Project” on page 26.)
On one TEETH house, DuPont’s
CM20 insulation was applied with
2.5 inches of ROCKWOOL Comfort­
board™
, then tested against the pink
foundation blanket of the other house.
“The results,” says Smetaniuk, “were
telling. When installing moisture-
sensitive insulation in moist areas,
it can lead to mould and mildew
growth and to decay, which can also
potentially affect home owner health.”
“In addition, basement blanket
insulation systems often get com­
pressed during installation, resulting
in lower overall effective R-values. The
hybrid rigid insulation system tested
in the study maintains its dimensional
stability and performs as intended,”
says Smetaniuk. “The rigid insulation
system of ROCKWOOL and DuPont was
found to perform at least 25% better
than the foundation blanket.”
Emma’s view on climate change
is to understand the science behind
it – so you can give voice to issues that
are contributing to it. She believes
travelling smart with alternative
means – like using carpools, cycling
and public transportation – can make
a huge impact. Working with the
ROCKWOOL team, Emma believes
their product is perfectly suited
to tackle many of today’s biggest
sustainability and development
challenges, from energy consumption
and noise pollution to fire resilience,
water scarcity and flooding.
Both Emma and ROCKWOOL would
welcome the chance to be on your
team. Don’t hesitate to contact them
for information on the Elite Builder
Program. They would like to show
you how they’ve helped other builders
meet the challenge of climate change
while constructing quieter, safer, more
comfortable and resilient homes. BB

Clearsphere and Empire were
looking to improve on the below-grade
basement insulation blanket and to
explore new systems that could create
better efficiencies in construction,
better comfort outcomes and long-
term durability. There has been a
concern with new-home builders
that installing a roll-down insulating
blanket was causing visible moisture
issues, thereby creating call backs
and warranty claims from clients.
Empire Communities – along with
Clearsphere, ROCKWOOL and
the Dow team – were interested
in comparing the blanket to their
innovative below-grade wall assembly.
George Brown College’s Building
Science Research Team monitored
above- and below-wall assemblies
and attic assemblies in two Empire
Communities homes to evaluate their
capacity to manage the movement of
heat and moisture effectively. Each
home was constructed with different
above- and below-grade wall assem­
blies to meet different levels of
standards and codes. The individual
wall assemblies in each home varied
from each other in terms of material
thickness and material properties.
The above-grade wall assemblies
in each house were measured against
current Ontario Building Code (OBC)
2012 standards and Energy Star
standards, as well as the anticipated
changes for the 2017 OBC and Energy
Star programs. The attic assembly
was measured against the 2012 OBC
and the proposed changes for the 2017
OBC. Lastly, base­ment assemblies
were tested against package J in Table
2.1.1.2.A in the 2012 OBC (the typical
industry standard for builders across
Ontario) and the anticipated changes
for the 2017 OBC.
The GBC team collected and
transmitted the data remotely for the
duration of a full heating and cooling
cycle, enabling for an assessment of
the durability and performance. Data
collected from each of the above- and
below-grade wall assemblies as well
as the attic was monitored, analyzed
and interpreted to provide insight
and validity to the effectiveness of
materials and assemblies and to verify
thermal resistance. Analysis included
moisture content, relative humidity

and Empire Communities, along with Dahai Zhang,
Dr. P. Christopher Timusk and Steffanie Adams of the Building Science Research
Team at George Brown College (GBC). The objective of the Empire Homes TEETH
project was to investigate improvements in below- and above-grade standard
residential building practice for Ontario builders.
Three different wall treatments tested together in hybrid house: R-22 glass fiber

a holistic analysis of the assemblies.
Lab tests were also conducted using a
guarded hot plate device to measure
the thermal conductivity of the
basement blanket wrap in various
states of compression. The results
from testing the thermal conductivity
of the mock-ups suggest that there is
a higher effective thermal resistance
with rigid material that does not
compress when it is installed.
Results of the research project
have just been released and there will
be further details to come. BB

f we consider the car an extension of
the home, then doing what we can
to remove gas cars from the road is a
big concern – especially given that in
the battle to reduce carbon, they pose
a larger issue than houses do.
As Lou Bada points out in his
column (“‘Charging’ Ahead with
Electric Vehicles,” page 3), poorly
conceived, government-mandated
regulations are not the answer.
But clearly there is a problem here,
as the current infrastructure, the
costs involved and the strain on
the electrical grid create a virtual
chicken/egg scenario that is stalling
electric vehicles (EVs) from reaching
critical mass.
However, a Scarborough, Ontario-
based company is shifting its battery
storage technology into the EV space
in an effort to help solve the logistical
challenges this industry currently
faces.
eCAMION was founded in 2009
and until recently was a community
energy storage provider, mostly work­
ing within the utilities, government
and heavy industrial sectors. The
company designed and manufactured
lithium ion battery storage, often
working with utilities such as Toronto
Hydro to install the units in remote
neighbourhoods that lacked sufficient
power quality, says Alice Wang,
eCAMION’s marketing specialist.
The company’s batteries provided
typical energy storage benefits, such
as power quality control and peak
shaving, and were designed to help
facilities use energy in a more efficient
way while lowering electrical bills.
In 2017, eCAMION opted to pivot its
target market towards the EV charging
sector. Wang says the company noted
the challenges this market faced, given
how power-intensive EV charging was
and the demand charges levied against
this application with how much electri­
city it drained. “That’s how eCAMION
decided to get into it,” she says.
The main issue facing EV owners is
an inability to charge their vehicle in
a timely manner. Currently, the most
popular models available are Level
Two chargers, which typically take five
to 10 hours to fully charge a vehicle’s
battery. That generally leaves owners
to either charge overnight, or simply
stop for an hour or so to top up.
Level Three chargers are much
faster (taking no more than an hour
to fully charge an EV), but are scarce
at this point. They also pose their
own challenges because, for a single
EV, a Level Three charger requires
the same amount of power from the
grid as 40 houses.
With the demand charges asso­

This technology will be showcased
in a government-funded pilot project
with Natural Resources Canada to
electrify a 3,400-kilometre stretch
of the Trans Canada Highway in
Manitoba and Ontario as the first leg
of the initiative.
Located in groups of three charging
stations, there will be 34 sites in total,
essentially 100 kilometres apart.
All told, there will be 102 charging
ports across this stretch, and upon
completion, they will explore
extending this across the rest of the
Trans Canada Highway.
While the government has adopted
an “if you build it, they will come”
mentality, selling this technology to
the private sector is another story.
Wang says one of the roadblocks is
that property managers of existing
buildings think it’s too expensive
to retrofit their electrical system to
ciated with consuming that much
power, small wonder it’s difficult for
operators to make a business case
for installing Level Three chargers.
Currently, Wang estimates, only about
10% of the few hundred charging
stations in the Greater Toronto Area
are Level Three, with the other 90%
being the slower Level Two models.
eCAMION is developing a customer-
facing EV charging sub-brand called
Jule Energy, under which it will target
this market. “It’s a super relevant
application for electric vehicles, both
now and in the future,” she says.
Supported by eCAMION’s tradi­
tional battery storage technology,
Jule Energy battery storage units will
be hooked up to EV charging stations,
thereby supporting the demand so
that the electricity is not being drawn
directly off the grid. “So basically,
the battery acts as a buffer,” Wang
explains.
The battery will charge from the
grid slowly overnight and during
off-peak hours, but will be capable of
dispensing power at high levels to an
EV charger. The system can support
any level of charging – even chargers
Level Four and above (known as “super
chargers”) that can fully charge an EV
in 10 to 20 minutes. “So the technol­
ogy is really getting to the point of gas
car convenience, almost,” she says.

support chargers, or they simply
believe the demand isn’t there to
warrant it.
But with the introduction of the
battery storage system, the business
case is easier to make as property
managers can better manage energy
within their buildings, perhaps
integrate the unit with a solar or wind
system, and support a row of eight, 10
or even 15 charging stations.
So there are multiple applications
for this technology, Wang says. “Think
of the battery as the hub to integrate
emerging energy and sustainability
technology.” BB

But this is the federal government
we are talking about, so the odds
are very high that they will not fully
understand the nuances needed for
our industry. Given the November 1
announcement of a 50% increase on
electricity rates in Ontario, reducing
our energy consumption is going
to become another major driver
affecting home buying and home
renovating affordability – especially
if the provincial government does
not apply another incentive to
reduce the consumer burden. For the
moment, let’s assume that we need
to go it alone and find ways to reduce
the impact of the carbon tax on the
end user (our home buyer) or home
renovation, as the case may be.
Here are five options that might
make a lot of sense in the near future
to help your consumer afford your
offering:
1.	 build a smaller home;
2.	 adopt a high-performance program
(make your homes super airtight
and add more insulation);
3.	 install right-sized high-
performance mechanical systems
with better windows;
4.	 use materials that sequester carbon
or have a low carbon impact for
value added; and
5.	 add solar generation.
Now, before you think that I’ve
gone off the deep end, let me walk you
through it. The first three options are
basic affordability decisions within
an Energy Star home, and number
4 is easy if you build with wood. As
for number 5? If you build a high-
performance home, you really don’t
need that much energy to power it.
When we built the Hope home a few
years ago, we were able to run the home
(including air conditioning during a
hot June) on 30 amperes. If we don’t
have to account for the occupant (and
all their TVs, computers, electronics,
washers and dryers and stoves, oh
my…), it’s not really that far fetched.
Let’s have a look.
Build a smaller home
There are quite a few factors here.
Besides the obvious fact that a smaller
home will be more affordable for
the consumer, you are using fewer
materials in the home, which reduces
the per-lot carbon footprint. The
operational carbon is also significantly
less. I looked at a 1,460-square-
foot bungalow built to Energy Star
that had a heating load of 19,200
BTUs and a cooling load of 16,000
BTUs; I compared it with our largest
production two-storey home (at 2,990
square feet), which came in at 32,500
BTUs heating and 21,600 BTUs cooling.
Once the basement was factored
into the home, the bungalow was
What’s Your Carbon Footprint?
I
t’s hard to believe that, in a few short years, we’ve gone from worrying about
if we can build to net zero to now facing some hard conversations about
dealing with the impact of the coming carbon tax. In the last edition, Lou Bada
eloquently laid out his concerns about the carbon tax being equated to a “sin
tax.” Lou believed that the carbon tax should not apply to buying a new high-
performance home or to doing a deep energy retrofit on an existing home, and
that our customers deserve a fair carrot for making these types of decisions. I
wholeheartedly agree with Lou.
Five Ways to Future Proof for the Carbon Tax

approximately 66% the size of the
larger two-storey and needed 59%
of the energy to heat and 74% of the
energy to cool (see table at right).
These homes are typical of
what you would see in a regular
subdivision. But with the crisis in
affordability, the desire for much
smaller homes is gaining a great deal
of attention. We are currently working
on a tiny-home community that will
have homes as small as 400 square
feet, and I can’t wait to see how low
the loads are for these homes.
Adopt a high-performance
home program
If you were to change your specs to the
Energy Star program, the total energy
consumption of the home would
drop by 25% to 30%, compared to
National Building Code (NBC) 2015.
Once you are able to build to Energy
Star, moving up to net zero-ready
is not much more than adding a bit
more insulation and making it super
tight. A net zero-ready home can be
as much as 70% to 80% more efficient
than an NBC 2015 built home and
can mean a massive reduction in CO2
emissions over the life of the home.
While some of us have spent
years figuring out how to make our
homes super airtight (less than 1.0
ACH), many builders I’ve talked to
don’t have any idea of how tight their
homes are. This is because they don’t
test – and often don’t want to know –
because they are concerned with the
cost to “fix it” if the home turns out to
be super leaky. But here is the really
great news: for a bit more than $1,000
net cost, most builders can get their
home to less than 1.0 ACH, simply by
filling the big holes, removing some
costly steps and using AeroBarrier
to air seal their home. All that time
wasted trying to seal up a home can
be done in as little as a half-day on the
job site. That’s a big-time solution to
the hardest part of getting to net zero.
Install right-sized high-
performance mechanical
systems with better windows
I look at mechanical systems and
windows together for the simple
reason that window selection affects
mechanical sizing. In these smaller/
tighter homes, it is the type and quality
of the window that is the next lowest-
hanging fruit. Improving your window
to triple glazed (U-value of 1.4 or
lower) will help with the heating load.
However, the biggest impact on HVAC
sizing is now the sensible cooling load
from the windows and the latent load
from humidity. Selecting a window
with a solar heat gain co-efficient
(SHGC) of less than 0.3 can reduce
your air conditioning requirements by
half a ton (or more) on a home. That
means a smaller air conditioner and
smaller duct sizing to help offset the
savings of picking the better windows.
It also provides greater comfort to the
occupant year-round and additional
carbon reduction.
Once you have your windows
selected, don’t let anybody change
them. Then, give this information to
the HVAC designer, who needs to be
current with the CSA F280-12 sizing
standard. It is somewhat alarming that
there are still many HVAC designers
out there using the old standard. If
you are not sure, check out the Master
Planning  Decision Guide for Natural
Gas Mechanical Systems, available
from Natural Resources Canada.
Use materials that sequester
carbon (or low-carbon impact)
I love wood. I love the smell of fresh
wood and the look of all that lumber
creating the skeleton of the homes we
build. I also love that wood is a carbon
sink and a sustainable construction
practice. But there are many more
products within a home.
Where possible, we are now looking
at products with low-carbon impact
and that are GreenCircle or GreenTag
certified. For example, BASF is now
offering a new version of their Walltite
(CM01) spray insulation that uses a
hydrofluoroolefin (HFO) blowing
agent, which has significantly less
carbon impact than their current
insulation, which uses a hydrofluoro­
carbon (HFC) blowing agent.

Add solar generation
Okay, so now we have a home that is
pretty much built to net zero-ready.
Add the solar panels and you’ve taken
another step to reduce your carbon
footprint. But what about the carbon
emissions during construction? What
if we were able to produce the needed
energy on the job site with a mobile
solar generator station? That’s crazy
talk, right?
Not so fast. A great number of
subtrades are now using an increasing
array of battery-powered tools, from
hammers, saws and screwdrivers to
paint sprayers, mixers and many more.
It’s already happening.
When we did Project Hope, we
supplied the majority of our energy
needs with a mobile solar energy station
from Anvil Crawler. It came equipped in
a 20-foot shipping container, including
a battery backup array. It may not meet
all of your needs, but for production
builders, it is an innovative solution.
Conclusion
I share this list of ideas to encourage
dialogue, in the hope that others will
join us on the journey to a lower-carbon
economy. By no means is this intended
to be the only solution. There are great
energy consultants available to help
builders find their way, and I encourage
industry stakeholders to work together
through voluntary programs to move
our industry forward.
What is missing? Like Lou said, it’s
the carrot. To add a carbon tax and not
incentivize the needed reductions in
our industry is a missed opportunity,
and we need to encourage our MPs
and MPPs to ensure it is implemented
fairly. BB

He described three historic phases in which civilization has developed. The first was the agricultural transition from a hunter-gatherer structure. The second was the industrial age, largely driven by the burning of cheap fossil fuels like coal and petroleum. The third is the information age, where we connect to the internet using our smartphones in a process that is highly dependent on base metals. We know now that the drivers of our prosperity have brought us to our current situation. When we think about Toffler’s quote today, the “big thing” is climate change. The “small things” are what we do to move towards resiliency and future proofing our homes. This is our annual future proofing issue. Inside, you’ll find information and tips on future proofing (the process of anticipating the future and developing methods to minimize the effects of future events) and resiliency (the capacity to recover quickly from difficulty). The Ontario Building Code package A1 reference house only requires 28 KBtu per hour on the coldest day of the year, but this load is too small for most furnaces. Our feature article on iGEN Technologies (page 16) explores a combination heating system that provides heat and hot water. It can power itself through a blackout in a winter storm by generating electricity. Dugald Wells from Marshall Homes is test driving this technology in his own cottage for potential use in a project in Pickering. In a now-repealed Code change, electric vehicle charging stations had been required to be roughed in. Lou Bada explains why he supports the repeal on page 3. In “Ready, Set, Charge!” (page 28), we profile eCAMION, a Scarborough company that knows bigger batteries in cars require new technology for rapid charging. Alice Wang explains how they are working toward a network of high-tech rapid charging stations. In “Resilient Construction” (page 5), Gord Cooke talks about resiliency planning for builders and how it can help us with a more demanding climate. Additionally, Doug Tarry reviews five significant ways we can reduce our carbon footprint (page 30). The third wave requires that we think differently, and collectively, about clean prosperity. The Sustainable Housing Foundation (SHF) brings together thought leaders, builders and manufacturers to create an informed path forward. You can find a recap of the recent Sustainable Housing Foundation Dinner on page 13. It seems fitting to quote Toffler again for his views of future success: “The illiterate of the future will not be those who cannot read and write but those who cannot learn, unlearn and relearn. If you do not have a strategy, you’re part of someone else’s strategy.” Ask yourself: Is your strategy stuck in the second wave or is it moving forward in the third wave?

  • 5. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 O ntario’s current Ministry of Municipal Affairs and Housing moved quickly in its mandate to repeal regulations in the Ontario Building Code requiring the rough-in of car charging stations in Part 9 buildings (low-rise) and suspended plans to implement them in larger buildings. This was met with great relief within our industry, but not for the reasons you might think. Cost implications are not the only thing on builders’ minds: we are more concerned with the implementation and the value proposition of new regulations for our customers. Although the policy to further “green-up” new homes through regulations is a no-brainer for any government looking to score cheap political points, putting the cart before the horse (or the charger before the electric vehicle [EV], as the case may be) ultimately creates bad policy. Here’s why. Many in our industry were quick to point out that requirements for car charger rough-ins were problematic and not well thought out. Our industry indicated we were willing to work on more rational solutions in order to achieve the goal of curbing carbon emissions. However, in expressing our concerns, we were often labelled as uninspired (or worse). The pitfalls, unworkability and ineffectiveness of the requirements mattered little to the policy makers as long as they could be seen to be doing the right thing. Although the goal of electrifying everything from housing to transportation seems like a good idea from 10,000 feet (given Ontario’s relatively low-carbon electrical generation system), builders have to build with their feet on the ground. When we examined Ontario’s microFIT program and reverse metering with photovoltaic solar panels, we quickly found out that the electrical grid was not always ready for a mass uptake of the new program. The infrastructure and utilities were often inadequate and unprepared. Similarly, when speaking to the local distribution companies (LDCs) about car charging stations, it appeared that our grid wouldn’t be ready for a mass uptake. If many people come home at the end of a work day, plug in their EVs and turn on the stove to cook dinner all at the same time, our electrical distribution system would be overwhelmed. However, builders were being compelled to put car charger rough-ins into thousands of new homes every year. It is not solely the problem of overall capacity of the electrical system: it’s the peak capacity of the system and infrastructure that matters more. “Peak shaving” and trying to match capacity and demand is the more salient issue for the LDCs. Utility scale energy storage systems are not adequately installed on Ontario’s energy grid. If we had to rough-in anything in a home, I believe it would be better to rough-in for home battery storage. A home battery could be charged off- peak and discharged on-peak. It could also charge a car while discharging on-peak. It would help the electrical grid “load-shift” and reduce the use of natural gas-fired “peaker plants.” A home storage battery could also provide some relief in the case of a blackout, which would also be a strategy for building in a measure of climate resilience. As the technology evolves and improves, battery prices will go down and electrical prices will go up. By using a home storage battery, home owners could realize the value proposition of storing electricity at home and take advantage of time- of-use rates. It would also be a step towards a distributed energy system. Following the argument above, you may ask: “Wouldn’t you still need a car charger and rough-in for a home?” Not necessarily. Firstly, we need to distinguish the level of charging most drivers will require. Builders were 3 1349968124/SHUTTERSTOCK thebadatest / LOU BADA ‘Charging’ Ahead with Electric Vehicles
  • 6. BETTERBUILDER.CA | ISSUE 32 | WINTER 20194 being asked to provide a rough-in for a 240-volt, 30-amp level 2 charger, which can charge an EV to travel about a 290-kilometre range over an eight-hour charge. A car charging unit and installation would have to be purchased by the home owner at significant additional costs. If, on the other hand, a purchaser wanted a level 1 charge, a regular 120-volt plug would suffice and give an EV a 65-kilometre range over an eight-hour charge. In this case, our rough-in would be a waste of material and money. According to Statistics Canada’s Journey to Work: Key Results from the 2016 Census survey, the median distance travelled to work for those who worked outside the home (6% work from home) was 8.7 kilometres (9.6 kilometres in Toronto). In Canada, 12.4% of people take public transit; in the Greater Toronto Area, that number doubles to nearly 25%. About 6.9% in urban areas walk or bike to work. If I were investigating the purchase of a new car, I would seriously look at a plug-in hybrid (PHEV), which has both an all-electric operating mode and a conventional gas engine operating mode (used after the battery has been fully discharged). There are a number of affordable PHEVs that can travel about 45 kilometres on an eight-hour, level 1 charge. I believe it would be perfectly adequate for most people, based on the Statistics Canada’s survey. A PHEV would also work better for those living in rural areas (who may need to drive further, more often) or drivers occasionally taking a long road trip. In light of this, why would we be mandated to install rough-ins for level 2 charging stations (with the requisite 200-amp service) in every new home today and in the foreseeable future, when someone could use a level 1 charger for their daily commute to work and back? New technology and level 3 chargers on a commercial basis are also evolving quickly and becoming more commonplace. At the time the requirements were in effect, I really believed that we were wastefully stranding a lot of infrastructure inside our houses for no good reason. Someday, driverless cars may make an appearance and upset the apple cart altogether. If that day comes, hopefully the horse will be pulling the cart and not vice versa. BB Lou Bada is vice- president of low-rise construction at Starlane Home Corporation and on the board of directors for the Residential Construction Council of Ontario (RESCON). 4 A PHEV would also work better for those living in rural areas (who may need to drive further, more often) or drivers occasionally taking a long road trip.
  • 7. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 A t the time of writing this article work is being completed on a new family cottage for my brothers and I and our growing extended families. The cottage is on the eastern shores of Lake Huron in Southampton, Ontario which means we will see the most beautiful sunsets unfold from the balcony all summer long and experience the wrath of relentless westerly winds howling across 80 kilometers of icy waters from Michigan all winter long. Regular readers of this magazine will recall we completed a modest Net Zero cottage in Southampton 4 years ago. Derek Seaman of Seaman and Sons Builders was so great to work with on that project, it was obvious we would be working with him again. That 2015 project was on a small infill lot 2 streets back from the shore and Derek was very quick to point out that building right on the shore had very different, exaggerated challenges. For that reason, while it was a given that we would be building again to the Canadian Home Builders Association Net Zero Labelling Program, we decided to add the theme of resilient construction to the project. As climate change and sustain­ ability permeates most every industry, a rather obvious response by the building industry would be, of course, to build ever more energy efficient homes. Perhaps, though, a more compelling story is to focus on the lasting legacy of the homes you build. I have the great pleasure of working with hundreds of builders across North America each year and I can say with complete confidence that every one of them takes pride in knowing that, unlike virtually any other consumer product, the projects they build will provide comfort and safety for generations of families. Homes designed to better handle the extremes of what ever Mother Nature has in store has been a consistent theme of every housing conference I have been to over the last 2 years. It will be no surprise that the specifics of the conversation always relate to the imminent risks of the region I happen to be in. In BC it’s about fire and seismic resiliency with the added challenge in coastal regions of months of rain with little time for drying. In California, the recent images of devastating wild fires fuelled by parched winds are driving design and construction decisions. In Texas and the Southeast of the US, right up into the Maritimes the conversations are about flooding and severe wind driven rain. In the Midwest, including our prairie provinces more frequent and more severe tornados dominant new design objectives. Thus, when we enlisted architect Mark Rosen of Building Energy Inc in Ottawa to design the project we asked him to consider the goal of a family cottage that should be enjoyed for generations to come and the 5 industryexpert / GORD COOKE Resilient Construction The Amvic R-30 ICF system forms the building’s structure.

Let me share just a few of those considerations and the decisions that followed, some that are simple and obvious and others that require changes to Derek’s normal build process. It started with the decision to build fully slab on grade, even though it might be normal to think of the extra living space that a basement would afford the extended family. The decision seemed vindicated even during the build as neighbours up and down the shore had to mobilize to clean up and dry out flooded basements due to one those seemingly more frequent harsh storms. That slab was protected by the 20 mil thick gas barrier called Radon Block that provides both superior moisture management and soil gas protection. The entire slab assembly shown in the picture here included the Radon Guard foam block that provides R10 insulation value while creating a vent space. This can be used to eliminate the need for the typical crushed stone under a slab. All together we ended up with approximately R28 under the slab, included the top layer of the AMPEX foam that allows for quick and effective installation of in-floor heating pipe.

  • 9. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 unless there is a code change. I would encourage all readers of this magazine who are clearly interested, as indicated by the title of the magazine, in the continual improvement of new homes to start including tie-down straps or strategies on every project. Then put a sample of these simple pieces of metal in the hands of every one of your salespeople. Let them know this is one of the most cost effective things any caring builder can do to ensure the resiliency of homes in the face of ever more severe storms. BB We have tracked the construction of the Cooke Family Cottage project through a series of film clips. I hope you will check those out at www.buildingknowledge.ca Gord Cooke is president of Building Knowledge Canada. we used a pretty standard 2x6 wall with exterior XPS foam insulation. In this project we felt an insulated concrete form structure provided the generational durability we were looking for. I was very pleased that at least one ICF manufacture, Amvic, has invested in the tooling to get to higher effective R-values than the typical industry R22. In this case we used their ICF-R30 product. This allowed us to get to the levels of wall insulation needed to achieve Net Zero with out adding supplemental insulation and still benefit from the inherent air tightness, thermal mass and climate resistance of a concrete structure. Winter power outages are pretty common in this windy area and it’s comforting for the family to know that the house will be freeze- protected for weeks at a time. Mark, the architect, envisioned the use a natural stone façade from a local quarry to create a protective boundary between the lake and the house. Drifting sand and wind driven rain always affect houses on this shoreline. With the water level up to historically high levels this year, up over 12 just this year over last, it is nice to have this feeling of safety, especially since it gives such a beautiful look as well. The prevailing architectural look on the lakefront in this area is a lapped wood siding and Mark wanted to retain that history even though painted wood takes a beating off the wind swept sand beaches. That look though is preserved with the use of a far more durable engineered wood siding product. In this case, the pre- treated substrate from LPs Smart Side format has a 50-year warranty and the paint coating is specifically engineered for the Canadian climate. I was particularly pleased that Derek always installs siding over strapping to ensure the optimized drainage and drying of a true rainscreen, backed up the DuPont Tyvek water management system. Although there are many other details that will ensure the resiliency of this family project that I hope to outline in future articles, there is one last one I want to mention in this article. There has been talk in the industry of our code being updated to include wind resistant elements that are common throughout the US. One example is the interest in roof tie- downs, often referred to as hurricane straps. The Institute for Catastrophic Loss Reduction (ICLR), established by a segment of the insurance industry and affiliated with the University of Western Ontario has been sponsoring research and submitting code requests for roof tie-down strategies. It is one of those low cost items that can be so quickly overlooked in construction and thus seldom implemented by builders 7 LP Smartside panels on strapping over a Tyvek “drain wrap” drainage plane.

  • 11. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 9 industrynews / PAUL DE BERARDIS If builders’ initiatives support the goals of government policy, we firmly believe they should be rewarded through some type of monetary incentive or carbon tax break for reducing carbon emissions in the homes they build. There are currently numerous different types of rebates and incentives that exist for auto manufacturers and car buyers in relation to hybrid and/or electric vehicles. And there are energy-efficient renovation rebates and tax credits that exist for home owners who try to improve the energy efficiency of their existing residences. As a matter of fact, the City of Toronto just launched their BetterHomesTO program to provide rebates and incentives for home owners and renters. However, once again, there’s nothing for builders and new-home buyers looking to ease the financial burden of building and buying a high-performance home. In terms of value for money, it is obviously much simpler and more cost efficient to construct energy-efficient homes from the get-go – especially since some components, like a wall assembly, are difficult to upgrade after the fact. Why not offer incentives for future-built homes rather than solely for existing homes, which face a much more costly and uphill battle to be retrofitted for energy efficiency? Look: we all know regulations continue to come down the pipeline to reduce GHG emissions from new homes. This is a highly regulated industry that becomes an easy target for rigorous performance mandates on new homes through mechanisms like the National Building Code (NBC) and Ontario Building Code (OBC), which up the ante on energy efficiency with every iteration. In addition, there are other municipal or regional government requirements – such as green standards, community energy plans or even energy mandates within subdivision agreements – that thrust additional beyond-Code measures onto new-home builders. The challenge for the home-building industry and their clients (new-home buyers) is that various levels of government are addressing their climate-change reduction targets through lowering GHG emissions on the backs of new- home buyers, further exacerbating housing affordability concerns. So how can builders soften both their own financial blow and the added costs borne by new-home buyers when it comes to improving energy efficiency and lowering GHG emissions? A framework needs to be created for home builders exceeding Code requirements and buyers alike to tap into the many tax breaks and rebates already offered to existing home owners (which seem to generally have little uptake). After all, we’re building houses that will be in operation for the next 75 to 100 years. The government needs to devise a means to incentivize more low-carbon new builds, without further financially burdening builders and home buyers. Under the federal carbon tax regime, many manufactured building products and materials will cost more for builders, who will then need to recoup those added costs from home buyers. Material costs for products such as concrete, insulation and masonry cladding will rise. We’re not knocking the carbon tax per se, but some of the funds generated from carbon taxation could possibly be directed to incentivizing high-performance homes – hence the GHGST concept. Let’s compare the home-building industry to the auto industry. There is a federal rebate (as well as various provincial rebates) for electric and hybrid vehicle purchasers, and these rebates are ultimately funded by Incentivize Green Construction and Builders Will Build It The government needs to devise a means to incentivize more low- carbon new builds, without further financially burdening builders and home buyers. H ave you ever thought about the greenhouse gas sales tax (GHGST)? Of course you haven’t. We made it up. But bear with us: what if this concept, the GHGST, was created to give the federal government (or even the provincial government) a revenue mechanism to incentivize home buyers to opt for new homes built with green building practices and technologies? And then, through a fully realized green program, builders could be given financial incentives to deliver this type of product.
  • 12. BETTERBUILDER.CA | ISSUE 32 | WINTER 201910 taxpayers – yet this analogy eludes governments when it comes to the new-home building market. To me, it seems like a win-win scenario, where housing affordability concerns and climate change woes can be addressed through the same green building incentivization policy. Through this same program – and bear with us, we’re throwing out ideas here – let’s set the table for builders and home owners to share in some type of carbon tax credit, tax break, rebate or whatever other creative policy mechanism to reward exceptional green building practices. Our friend, Better Builder publisher John Godden of Clearsphere, was involved in rating 1,523 homes last year built to standards beyond the OBC. There are five builders shown in the chart below. They deserve more credit for reducing carbon because they produced 15% less CO2 emissions 2018 residential builder ad Designs that install faster and connections you can count on with customer care that gives you confidence to advance your business.

  • 13. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 than other builders in other provinces who build strictly to NBC. When we benchmark these builders’ homes built in 2019 compared to the NBC emissions, the chart shows how many cars they took off the road by building houses that were 30% more efficient. These five builders’ homes have taken 475 cars off the road per year in perpetuity (think five tonnes of CO2 per car against reductions). While that makes a difference, we have to be vocal and engage with government so they can understand and also support what our industry is doing to make a difference. In fact, there is more potential to making houses greener than cars because of their vastly longer lifespan – you can get maybe 10 to 15 years out of a brand new car before it is replaced or scrapped, whereas a home has a useful service life of at least 75 years. You tell me: where is there more bang for your buck when it comes to reducing emissions? So we’re suggesting various levels of government engage with the building industry to support and incentivize low-carbon, new-home building. Sure, the government can continue gradually raising the bar simply through increasing regulation – but to truly get builders and home buyers on board in a meaningful way, they need the financial support to bring high- performance building to the masses. A high-performance green home should get incentives: the buyer needs an incentive to buy it, but the builder also needs incentives to build it so that it’s still financially accessible to consumers. Everyone loves Tesla as a disruptive game-changer – so why can’t we do the same with high-performance green homes? Where will that Tesla be in 100 years – when today’s new homes are still standing, while contributing less and less to greenhouse gases? Let’s give the GHGST concept some serious consideration.

BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 13 industrynews / ALEX NEWMAN M ichael Bernstein is no stranger to party politics – and he’s heard pretty much every question there is about carbon tax. He believes that the carbon tax is the best action to lower costs while spurring innovation in the economy. And he’s not alone in that view, either – he points out that putting a price on carbon use is widely considered as the most affordable way of reducing carbon while staying profitable. The 30-something director of Canadians for Clean Prosperity has plenty of experience in this area. He has an economics degree from Yale and a master’s in public administra­ tion from Harvard, plus practical experience as director of two profitable organic food delivery companies (Mama Earth and Farms Forks). Speaking at a recent Sustainable Housing Foundation dinner, he says he tries “to walk people through the logic of carbon tax, why it’s needed and why it should not be a partisan issue.” Although the provincial and federal Conservatives are in favour of eliminating the carbon tax, Bernstein observes that the tax doesn’t have to run counter to conservative values: “Preston Manning, for example, is in favour [of carbon pricing]. Mark Cameron, senior policy advisor to [Stephen] Harper, is in favour. Conservatives have led on environmental issues in the past – like Brian Mulroney, who made an impact on the environment by taking Clean and Green Making the Case for a Canadian Carbon Pricing Policy PHOTOGRAPHYBYMIKEDAY Top: Michael Bernstein of Canadians for Clean Prosperity presents the economics of carbon taxation.

At the end of the day, though, this should not be a partisan issue.” While he agrees with a more conservative/less interventionist perspective, he notes that “if you want to address climate change, there are only two ways to go about it: [either] set a price on carbon pollution and let business owners figure out how to work around that, or have government step in and dictate how to reduce emissions.” It would be fair to say that the 85 people who attended the event were committed to greener construction practices. Even so, Bernstein says there were lots of questions about carbon pricing and varying view­ points on the policy. He explains that “the money goes back to you first, and then you decide what you want to do: pay higher prices on what you used to pay, or save money by purchasing things that are not manufactured by those who pollute. It’s like finding a $20 bill on the sidewalk. The money is there; the choice is yours whether you’ll pay up for something that pollutes or save the money.” How it affects business – and builders – is a question he gets a lot. The answer is that the federal government has compensation programs around energy efficiency. He points specifically to two programs that provide grants of up to 50% on home retrofits and new energy equipment, like HVAC and boilers. Bernstein argues the programs “should stimulate some new construction demand. These funds comprise about 7% of the total carbon tax revenue.” But the biggest possible benefit to builders is “avoiding the economic consequences that come with a warming climate, something the Bank of Canada (BOC) has warned is a major threat to the Canadian economy. In fact, the BOC sees investors pulling out if a company doesn’t have a sustainability plan in place. This affects the economy directly.” While net zero is technically feasi­ ble through the use of more efficient envelopes and mechanical systems, it would add substantial costs to build­ ing. But Bernstein expects that will change “since the pace of technologi­ cal innovation happens very fast. Take the battery and solar panel industry – the price has come down a lot, and home owners are very interested.” Growth spurs more growth – and with the rapid rise of the clean tech sector, ever more energy-efficient products are coming to market. The demand for green building will continue as buyers become more informed, and wise builders will prepare now to capitalize on that, Bernstein says. Tridel, for example, is currently piloting CarbonCure concrete products in their buildings. “Consumers are increasingly going to look for, and even expect, these things when they set out to purchase a home. If you build homes that are ready for an EV [which had been part of the Ontario Building Code until the provincial government recently rescinded it], for example ... consumers will be appreciative,” Bernstein says. He adds that builders who are on the cutting edge of low-carbon construction should be able to export their knowledge to other jurisdictions. Although the Doug Ford government has put the carbon tax on the shelf for the time being, Bernstein argues that the carbon tax is inevitable. China has now put carbon pricing in place, and the US has carbon pricing on a third of its economy. “From a business perspective, the world is moving to a cleaner economy, which means renewable energy and products will be at a premium. We should capitalize on that now – because if we delay, we’ll miss the opportunity and ultimately our economy will suffer.” Sixteen-year-old Greta Thunberg has shown the importance of climate change activism around the world, including in Canada. Nevertheless, Bernstein writes in a recent Maclean’s article that “it’s also important for [Canadians] to know that we don’t all have to stop flying, swear off meat or close down our heavy industry to address climate change.” Instead, we already have a much better solution: an economy-wide carbon tax and rebate.

Bernstein explains that “the money goes back to you first, and then you decide what you want to do: pay higher prices on what you used to pay, or save money by purchasing things that are not manufactured by those who pollute.”
  • 18. BETTERBUILDER.CA | ISSUE 32 | WINTER 201916 W hen talking to people about his company’s product, Alan Clarke likes to say: “iGEN has solved a problem that most people don’t even know they have until it’s too late.” The chief business strategy officer of six-person iGEN Technologies (based out of Richmond Hill, Ontario) is referring to a challenge many home owners in Ontario have faced in recent years – namely, power outages in cold weather. The one essential thing you need to be func­ tional during a winter power outage is your furnace – but given that it’s an appliance that requires two power inputs (natural gas/propane and electricity), when the lights go out, so does the heat. It was this exact scenario that sparked an idea for engineers Michael Chatzigrigoriou and Patrick Lai, who suffered a lengthy power outage in the wake of an ice storm in 2012. Clarke says that the two HVAC consultants came to the conclusion that “this is ridiculous; this is what we do for a living, and we can’t heat our own homes.” featurestory / ROB BLACKSTIEN A small Richmond Hill company may have the next big thing in home heating innovation on its hands. The Heat IsOn
  • 19. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 The pair determined that there had to be a better way. They set about creating a self- powered furnace, a concept that – when pre­ sented to the masses – elicits plenty of ‘why didn’t I think of that?’ reactions, Clarke says. Chatzigrigoriou and Lai spent about a year building a prototype and, by 2013, what would become the i2 was born. At this point, the pair decided to devote themselves to the project full-time in an effort to bring the product to market. Running Itself The i2 uses natural gas or propane, converting that energy into heat and enough electricity to run not only itself when the power goes out, but also a hot water heater, with enough surplus to keep your modem running and your cell phone charged. The benefits the unit offers are plentiful, including utility cost savings from a more efficient heating appliance, environmental benefits (given that the i2 results in lower greenhouse gas emissions than traditional heating appliances) and the peace of mind that home heating won’t be affected by a blackout or utility interruption. While there was an early investor in the company (who has since been bought out), iGEN has been mostly self-financed and is now 100% owned by Chatzigrigoriou, Lai and the team. Clarke says the company also received grants from various government agencies and industry associations and is currently engaged in efforts to raise more equity to “fuel our growth” – no pun intended. The original concept for the i2 was a single unit, but the box was extremely heavy and large – about 50% wider than a traditional furnace, meaning it couldn’t fit through standard-sized doorways. At this time (late 2017), the i2 was being tested at three independent labs. Once the performance data was verified, the next stage was to streamline the product down to a more manageable size. The answer came in serendipitous form, as UK-based competitor Flowgroup plc had developed a product that operated on a similar principle (a replacement for residential boilers that generated an electricity stream that could be sold back to the grid). The company was running into some difficulties, so it wound up disposing of the business unit. iGEN pounced, taking Flowgroup’s inven­ tory of about 1,000 units off its hands and gaining the rights to the worldwide patents and intellectual property. 17 VANESSACLARKE Alan Clarke of iGEN Technologies (left) and Dugald Wells of Marshall Homes are testing iGEN’s i2 units in Wells’s new cottage.
  • 20. BETTERBUILDER.CA | ISSUE 32 | WINTER 201918 Solving Issues This solved a couple of issues for iGEN. First, they were able to overcome the challenge of how to separate the heat and electricity generation from the heat distribution in the home. Second, by breaking the solution into two pieces, the size issue was resolved. Now, there’s a wall-hung piece (the boiler unit and vapour expansion cycle module, which generates the heat and electricity) and a floor unit that replaces the furnace, which includes a heat exchanger with a blower fan. Heat is transferred from the boiler unit to the heat exchanger with a hot water loop. While the i2 uses the same ductwork as existing gas furnaces, Clarke explains that the installation process is a bit different, but traditional furnace installers should have no issues mastering it. Still, the product is so unique that gaining certification for selling the i2 in North America has proved challenging because, Clarke explains, no standard currently exists for self- powered appliances. In fact, iGEN is working with the Standards Council of Canada to develop a standard for this product, something it hopes is com­ pleted later this year or early in 2020. In the meantime, iGEN has been granted approval to run an early adopter program – an initiative that’s generated promising results, including an estimated $1,863 utility cost savings over a 10-year period in a 1,500-square-foot home. The case study numbers were provided by third- party simulations, so they are merely estimates, Clarke says. But he adds that the company is heavily monitoring these initial field installs to get a more accurate sense of the annual savings. Early Adopters Clarke says the 44,000 BTU per hour output i2 is ideal for homes between 1,000 and 2,200 square feet, depending on the house age, quality of construction, tightness of envelope and insulation quality. According to Clarke, another 20 to 40 early adopter installs are planned before the end of 2019, but none may be more important than the i2 that’s being tested in Dugald Wells’s new cottage. That’s because this trial is not simply for a customer, but possibly a key business partner. Wells is the general manager of Pickering-based Marshall Homes, an innovator in energy-efficient housing and a company that’s keenly interested to see if the i2 is ready for prime time. Wells had been familiar with iGEN for some time, thanks to his long association (both professionally and personally) with Clarke, who himself first heard of iGEN while he was doing consulting work for Marshall Homes. In the walkout section of the cottage, Wells had roughed in for radiant floor heating, but was unsure he was going to go that route given that it would require a second boiler. He says what really caught his attention was when he heard about iGEN’s acquisition of Flowgroup’s busi­ ness unit because, over in the UK, it’s generally all hydronic heating, he says. Wells’s goal was to tap off the iGEN’s coil – the boiler in the UK version – to take hot water to use in the radiant flooring loop as well as for the forced air, “because otherwise I would have to buy a whole new furnace.” Running the Numbers Wells approached Clarke to find out whether this would work. The iGEN team went off, did a bunch of calculations and determined that it could in fact be done. The i2 heating system installed and monitored in Coach House. COURTESYiGENTECHNOLOGIES
  • 21. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 “So, with one unit, I am serving both my radiant floor heating loop as well as my forced air distribution,” Wells says. This offers multiple benefits, as his forced air system will run less often, and the radiant floor heating is more comfortable than forced air. It will deliver more even temperatures, greater energy efficiency, more comfort and fewer noise and temperature fluctuations with the forced air going on and off. 19 When Wells test drives the i2 this winter, it will be because Marshall Homes is considering adding the unit into the homes in an upcoming and very unique new housing development. Altona Towns, a 27-townhome project in Pickering, “goes right to the heart of how the electricity market works in this province.” This ambitious project is a window into the future of housing, featuring a community that will be powered by a microgrid, thereby reducing both utility bills and carbon footprint. It features a solar array and a powerful standalone battery made by Tesla. The Tesla Powerpack is a fully integrated energy storage system that includes DC batteries, a bi-directional inverter and a Powerpack controller with intelligent software. It delivers multiple applications, including peak shaving, load shifting and emergency backup.

  • 22. BETTERBUILDER.CA | ISSUE 32 | WINTER 201920 By being deemed a special demon­ stration project, Altona Towns was able to barter an agreement with utility company Elexicon and Opus One (which creates grid control software) so that – in the absence of virtual net metering – the condo corporation will be compensated for all the power generated that becomes available to the grid. The residents will benefit from this through reduced condo fees. Wells said they had to come up with this plan “because government policy is still in the dinosaur age.” Cogeneration This brings us to the issue of cogener­ ation (or combined heat and power (CHP)) and the possibilities it creates. Currently, Wells says, it’s a one-way street, in which the utility gives you power and you give them money. So, if you want to have your own power generation or storage, you’re on your own (with the exception of special deals involving wind or solar farms). CHP systems tend to be large-scale grids, and micro CHPs are for small communities. Clarke calls their system “nano CHP” because it’s simply for the appliance. “We’re not trying to power the whole house; we’re just a better heating plant,” Clarke says. Wells will put that theory to the test this winter as a trial run for much bigger things. “We’re interested, but ... at the end of the day, we’ve got to satisfy 27 home owners and we want to make sure that equipment functions as advertised,” he says. This will be determined by his own findings, the results from the other early adopters, and how iGEN’s service and response holds up should there be any issues. If nothing else, Wells’s neighbours are fascinated by his cottage plans. He had a group of friends over and was showing them the i2. Suddenly, Wells was backed into a corner where a pile of wood lay, surrounded by a transfixed audience gathered in a semi circle. So, he found himself on top of the wood pile, lecturing about the technology as they lobbed question after question at him. Obviously, there’s interest in this. Lots at Stake And just as clearly, there’s a lot at stake for iGEN over the next few months, but Clarke is bullish. “Depending on how well we are able to perform in Dugald’s cottage this winter, I think if everything goes as well as we expect it will, that will make a stronger case for Marshall Homes to include our units,” he says. For Wells’s part, while he’s with­ holding judgment on the technology for the time being, he’s already made up his mind about the people behind the i2. As an entrepreneur himself, he has a good sense of what it takes to make it, and he sees those qualities in iGEN. “I’m really impressed with them. They’re calm, they’re thoughtful.” The fact that they’ve been at it for a few years – with great personal sacrifice – speaks to their commitment, he adds. “They’re not a flash in the pan.” Wells says if he were a Dragon’s Den investor, he’d be quite interested in iGEN: “I like what I see, but it’s early days. They’ve got a lot to prove.” The opportunity for iGEN to prove it’s ready for prime time begins in earnest now. BB Rob Blackstien is a Toronto-based freelance writer.

BETTERBUILDER.CA | ISSUE 32 | WINTER 201922 sitespecific / ALEX NEWMAN I f there’s one thing you can do with today’s buildings that makes financial and environmental sense for the future and is the number one way of mitigating climate change, it would be “improve your insulation,” says Emma Smetaniuk, commercial and residential sales representative for ROCKWOOL™ . That’s not just her opinion, though – it’s also the opinion of the International Renewable Energy Agency (IRENA). Smetaniuk never expected to work in the construction materials industry but, looking back, it all makes sense now. Emma’s father was in the construction business, as a framer, for over 30 years. He was always a fan of stone wool insulation when he was building houses. After university – Oswego in New York on a hockey scholarship! – she returned to Canada to work for Lafarge in their leadership and development program. “It was a fantastic opportunity; I got to grasp multiple product lines and jobs within the industry. I was very thankful for the opportunity, especially the mentorship,” she says. But when the sales opportunity arose at ROCKWOOL four years later, Smetaniuk took to how the company positively contributes to our overall health and well-being. The importance of what we do with today’s buildings – and how we move forward with newer builds and renovations – essentially determines the legacy we leave for future generations. “ROCKWOOL is a leader in high-performance and quality stone wool insulation, and I wanted to be part of it,” Smetaniuk explains. ROCKWOOL’s particular suitability to the task certainly makes Smetaniuk’s job easier: “The product has a massive list of qualities capable of contributing to the fight against our biggest environmental challenges.” She starts with how durable, hydrophobic and mould- and mildew-resistant the product is. It’s also permeable, breathable, fire resilient and energy saving, and has dimensional stability, she adds. It can also take the heat, thanks to a much higher melting point than other insulation. “You can literally take a blow torch to it, and it won’t burn. Actually, it can withstand temperatures of up to 1,177 °C,” Smetaniuk says. “That’s important in residential use, especially now that we’re building homes much closer together – duplexes, semis, condos, multi-units and mid- rise wood frame buildings. Stone wool is non-combustible and ideal to satisfy building code requirements for zero lot line applications. Even detached homes are closer.” Because ROCKWOOL is hydro­phobic – that is, water repellent – it’s effective when there are compromises in the building envelope, Smetaniuk says. “The inorganic composition makes ROCKWOOL mould and mildew resistant, so if condensation were to get trapped in, it wouldn’t affect the material. In addition, its high vapour permeance maximizes the drying potential if there is moisture present in the wall assembly.” As well, the thermal comfort it provides can’t be underestimated. Proper insulation can reduce a build­ ing’s heating needs by up to 70% by helping to create an airtight building envelope, along with proper air barrier detailing. This seals out drafts so interiors aren’t only more comfortable, but cost less to heat and cool. “Due to the product’s physical structure, ROCKWOOL Uses a Team Approach When Working with Builders Emma Smetaniuk of ROCKWOOL.
  • 25. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 density and thermal properties, ROCKWOOL insulation saves energy by maintaining indoor temperatures for all climates,” she notes. The acoustic benefits also contribute to overall well-being. When the party wall cavities between duplexes or towns are filled with ROCKWOOL insulation, you get quieter rooms on either side. That works as well for schools and office buildings, which makes for better learning and work environments. ROCKWOOL batt insulation is friction fit and prevents gaps, thus decreasing sound transmission from room to room. Typical code party walls have sound transmission class (STC) ratings of 53. Using ROCKWOOL can yield an STC of up to 60. Like any premium product, you pay a bit more for it – but it pays huge dividends. For example, energy efficiency is enhanced, energy costs are reduced and overall indoor air quality is improved, as the material has a GREENGUARD® Gold certification. This certification indicates lower product emissions and actually garners LEED points. The company has paired up with several builders, including Cleary Homes, Absolute General Contractors, Brookfield Residential, Empire TEETH Homes and Doug Tarry Homes. The Tyendinaga Mohawk Territory in Deseronto (near Quinte) is using ROCKWOOL in a new fourplex, for which Absolute General Contractors is hoping to achieve LEED Gold certification. Emma’s competitive hockey days taught her the importance of being a team player. As such, she is very supportive in her relationship to builders. A good example is Cleary Homes, with whom ROCKWOOL worked on 30 homes in the Orchard East Community in Bowmanville. Cleary provided a finish-ready basement detail consisting of Comfortboard™ (R-6) and Comfortbatt® (R-14) on all 30 homes. Working with both Cleary Homes and Absolute General Contractors was a real honour because those companies saw the benefit of such a sustainable product and how that contributes to the overall health and well-being of the future home owners.

ROCKWOOL has been developing its Elite Builder Program, which aims to educate builders in determining which products work best with their projects. In fact, its building science and technical support team provides complimentary services to help builders, architects and designers find ways to increase their buildings’ energy efficiency. The end goal, Smetaniuk says, is to provide builders with the tools required to construct high- performance buildings that reduce operating costs, enhance safety and maximize occupant comfort. All these factors enhance a builder’s brand through home owner experience. Three popular products comprise the lion’s share of ROCKWOOL’s residential line: ROCKWOOL Comfortbatt® , Safe’n’Sound® and Comfortboard™ . Comfortbatt® is used to insulate exterior walls, ceilings, ex- posed floors, attics and basements, to keep heat in and cold out and deliver a top R-value to the home. Safe’n’Sound® adds fire protection and sound damp­ening and is used in interior walls and ceilings and between floors. Comfortboard™ is a rigid insulation board that is denser than our batts and is typically used above and below grade as a continuous insulation layer. It’s suitable for both commercial and residential applications, but it is especially good in basements. In the fourplex being constructed for the Mohawks of the Bay of Quinte by Absolute General Contractors, two inches of Comfortboard™ was used in the crawl space to thermally protect the insulating concrete form (ICF) foam foundation. The main exterior walls and party walls are insulated with Comfortbatt® . Using ROCKWOOL secures more points, which Absolute General Contractors needs for a LEED Gold certification. Comfortboard™ was also used in a recent research project run by George Brown College, but initiated by ROCKWOOL, Empire Communities, Clearsphere and DuPont. The idea was to install insulation into three homes and monitor the results. George Brown’s building science research team monitored the assemblies, evaluated the homes’ capacity for handling heat and moisture, and looked for ways to improve above- and below-grade insulation to pass on to Ontario builders. (See “TEETH Checkup: A Look inside a Collaborative Research Project” on page 26.) On one TEETH house, DuPont’s CM20 insulation was applied with 2.5 inches of ROCKWOOL Comfort­ board™ , then tested against the pink foundation blanket of the other house. “The results,” says Smetaniuk, “were telling. When installing moisture- sensitive insulation in moist areas, it can lead to mould and mildew growth and to decay, which can also potentially affect home owner health.” “In addition, basement blanket insulation systems often get com­ pressed during installation, resulting in lower overall effective R-values. The hybrid rigid insulation system tested in the study maintains its dimensional stability and performs as intended,” says Smetaniuk. “The rigid insulation system of ROCKWOOL and DuPont was found to perform at least 25% better than the foundation blanket.” Emma’s view on climate change is to understand the science behind it – so you can give voice to issues that are contributing to it. She believes travelling smart with alternative means – like using carpools, cycling and public transportation – can make a huge impact. Working with the ROCKWOOL team, Emma believes their product is perfectly suited to tackle many of today’s biggest sustainability and development challenges, from energy consumption and noise pollution to fire resilience, water scarcity and flooding. Both Emma and ROCKWOOL would welcome the chance to be on your team. Don’t hesitate to contact them for information on the Elite Builder Program. They would like to show you how they’ve helped other builders meet the challenge of climate change while constructing quieter, safer, more comfortable and resilient homes.

There has been a concern with new-home builders that installing a roll-down insulating blanket was causing visible moisture issues, thereby creating call backs and warranty claims from clients. Empire Communities – along with Clearsphere, ROCKWOOL and the Dow team – were interested in comparing the blanket to their innovative below-grade wall assembly. George Brown College’s Building Science Research Team monitored above- and below-wall assemblies and attic assemblies in two Empire Communities homes to evaluate their capacity to manage the movement of heat and moisture effectively. Each home was constructed with different above- and below-grade wall assem­ blies to meet different levels of standards and codes. The individual wall assemblies in each home varied from each other in terms of material thickness and material properties. The above-grade wall assemblies in each house were measured against current Ontario Building Code (OBC) 2012 standards and Energy Star standards, as well as the anticipated changes for the 2017 OBC and Energy Star programs. The attic assembly was measured against the 2012 OBC and the proposed changes for the 2017 OBC. Lastly, base­ment assemblies were tested against package J in Table 2.1.1.2.A in the 2012 OBC (the typical industry standard for builders across Ontario) and the anticipated changes for the 2017 OBC. The GBC team collected and transmitted the data remotely for the duration of a full heating and cooling cycle, enabling for an assessment of the durability and performance.

BETTERBUILDER.CA | ISSUE 32 | WINTER 20192828 buildernews / ROB BLACKSTIEN I f we consider the car an extension of the home, then doing what we can to remove gas cars from the road is a big concern – especially given that in the battle to reduce carbon, they pose a larger issue than houses do. As Lou Bada points out in his column (“‘Charging’ Ahead with Electric Vehicles,” page 3), poorly conceived, government-mandated regulations are not the answer. But clearly there is a problem here, as the current infrastructure, the costs involved and the strain on the electrical grid create a virtual chicken/egg scenario that is stalling electric vehicles (EVs) from reaching critical mass. However, a Scarborough, Ontario- based company is shifting its battery storage technology into the EV space in an effort to help solve the logistical challenges this industry currently faces. eCAMION was founded in 2009 and until recently was a community energy storage provider, mostly work­ ing within the utilities, government and heavy industrial sectors. The company designed and manufactured lithium ion battery storage, often working with utilities such as Toronto Hydro to install the units in remote neighbourhoods that lacked sufficient power quality, says Alice Wang, eCAMION’s marketing specialist. The company’s batteries provided typical energy storage benefits, such as power quality control and peak shaving, and were designed to help facilities use energy in a more efficient way while lowering electrical bills. In 2017, eCAMION opted to pivot its target market towards the EV charging sector. Wang says the company noted the challenges this market faced, given how power-intensive EV charging was and the demand charges levied against this application with how much electri­ city it drained. “That’s how eCAMION decided to get into it,” she says. The main issue facing EV owners is an inability to charge their vehicle in a timely manner. Currently, the most popular models available are Level Two chargers, which typically take five to 10 hours to fully charge a vehicle’s battery. That generally leaves owners to either charge overnight, or simply stop for an hour or so to top up. Level Three chargers are much faster (taking no more than an hour to fully charge an EV), but are scarce at this point. They also pose their own challenges because, for a single EV, a Level Three charger requires the same amount of power from the grid as 40 houses. With the demand charges asso­ Ready, Set, Charge!

BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 This technology will be showcased in a government-funded pilot project with Natural Resources Canada to electrify a 3,400-kilometre stretch of the Trans Canada Highway in Manitoba and Ontario as the first leg of the initiative. Located in groups of three charging stations, there will be 34 sites in total, essentially 100 kilometres apart. All told, there will be 102 charging ports across this stretch, and upon completion, they will explore extending this across the rest of the Trans Canada Highway. While the government has adopted an “if you build it, they will come” mentality, selling this technology to the private sector is another story. Wang says one of the roadblocks is that property managers of existing buildings think it’s too expensive to retrofit their electrical system to ciated with consuming that much power, small wonder it’s difficult for operators to make a business case for installing Level Three chargers. Currently, Wang estimates, only about 10% of the few hundred charging stations in the Greater Toronto Area are Level Three, with the other 90% being the slower Level Two models. eCAMION is developing a customer- facing EV charging sub-brand called Jule Energy, under which it will target this market. “It’s a super relevant application for electric vehicles, both now and in the future,” she says. Supported by eCAMION’s tradi­ tional battery storage technology, Jule Energy battery storage units will be hooked up to EV charging stations, thereby supporting the demand so that the electricity is not being drawn directly off the grid. “So basically, the battery acts as a buffer,” Wang explains. The battery will charge from the grid slowly overnight and during off-peak hours, but will be capable of dispensing power at high levels to an EV charger. The system can support any level of charging – even chargers Level Four and above (known as “super chargers”) that can fully charge an EV in 10 to 20 minutes. “So the technol­ ogy is really getting to the point of gas car convenience, almost,” she says. 29 support chargers, or they simply believe the demand isn’t there to warrant it. But with the introduction of the battery storage system, the business case is easier to make as property managers can better manage energy within their buildings, perhaps integrate the unit with a solar or wind system, and support a row of eight, 10 or even 15 charging stations. So there are multiple applications for this technology, Wang says. “Think of the battery as the hub to integrate emerging energy and sustainability technology.” BB Rob Blackstien is a Toronto-based freelance writer.

An Audi Etron plug-in hybrid gets charged by an eCamion transportable level 3 charging station.

BETTERBUILDER.CA | ISSUE 32 | WINTER 201930 fromthegroundup / DOUG TARRY But this is the federal government we are talking about, so the odds are very high that they will not fully understand the nuances needed for our industry. Given the November 1 announcement of a 50% increase on electricity rates in Ontario, reducing our energy consumption is going to become another major driver affecting home buying and home renovating affordability – especially if the provincial government does not apply another incentive to reduce the consumer burden. For the moment, let’s assume that we need to go it alone and find ways to reduce the impact of the carbon tax on the end user (our home buyer) or home renovation, as the case may be. Here are five options that might make a lot of sense in the near future to help your consumer afford your offering: 1. build a smaller home; 2. adopt a high-performance program (make your homes super airtight and add more insulation); 3. install right-sized high- performance mechanical systems with better windows; 4. use materials that sequester carbon or have a low carbon impact for value added; and 5. add solar generation. Now, before you think that I’ve gone off the deep end, let me walk you through it. The first three options are basic affordability decisions within an Energy Star home, and number 4 is easy if you build with wood. As for number 5? If you build a high- performance home, you really don’t need that much energy to power it. When we built the Hope home a few years ago, we were able to run the home (including air conditioning during a hot June) on 30 amperes. If we don’t have to account for the occupant (and all their TVs, computers, electronics, washers and dryers and stoves, oh my…), it’s not really that far fetched. Let’s have a look. Build a smaller home There are quite a few factors here. Besides the obvious fact that a smaller home will be more affordable for the consumer, you are using fewer materials in the home, which reduces the per-lot carbon footprint. The operational carbon is also significantly less. I looked at a 1,460-square- foot bungalow built to Energy Star that had a heating load of 19,200 BTUs and a cooling load of 16,000 BTUs; I compared it with our largest production two-storey home (at 2,990 square feet), which came in at 32,500 BTUs heating and 21,600 BTUs cooling. Once the basement was factored into the home, the bungalow was What’s Your Carbon Footprint? I t’s hard to believe that, in a few short years, we’ve gone from worrying about if we can build to net zero to now facing some hard conversations about dealing with the impact of the coming carbon tax. In the last edition, Lou Bada eloquently laid out his concerns about the carbon tax being equated to a “sin tax.” Lou believed that the carbon tax should not apply to buying a new high- performance home or to doing a deep energy retrofit on an existing home, and that our customers deserve a fair carrot for making these types of decisions. I wholeheartedly agree with Lou. Five Ways to Future Proof for the Carbon Tax 172977688/ISTOCKPHOTO
  • 33. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 approximately 66% the size of the larger two-storey and needed 59% of the energy to heat and 74% of the energy to cool (see table at right). These homes are typical of what you would see in a regular subdivision. But with the crisis in affordability, the desire for much smaller homes is gaining a great deal of attention. We are currently working on a tiny-home community that will have homes as small as 400 square feet, and I can’t wait to see how low the loads are for these homes. Adopt a high-performance home program If you were to change your specs to the Energy Star program, the total energy consumption of the home would drop by 25% to 30%, compared to National Building Code (NBC) 2015. Once you are able to build to Energy Star, moving up to net zero-ready is not much more than adding a bit more insulation and making it super tight. A net zero-ready home can be as much as 70% to 80% more efficient than an NBC 2015 built home and can mean a massive reduction in CO2 emissions over the life of the home. While some of us have spent years figuring out how to make our homes super airtight (less than 1.0 ACH), many builders I’ve talked to don’t have any idea of how tight their homes are. This is because they don’t test – and often don’t want to know – because they are concerned with the cost to “fix it” if the home turns out to be super leaky. But here is the really great news: for a bit more than $1,000 net cost, most builders can get their home to less than 1.0 ACH, simply by filling the big holes, removing some costly steps and using AeroBarrier to air seal their home. All that time wasted trying to seal up a home can be done in as little as a half-day on the job site. That’s a big-time solution to the hardest part of getting to net zero. Install right-sized high- performance mechanical systems with better windows I look at mechanical systems and windows together for the simple reason that window selection affects mechanical sizing. In these smaller/ tighter homes, it is the type and quality of the window that is the next lowest- hanging fruit. Improving your window to triple glazed (U-value of 1.4 or lower) will help with the heating load. However, the biggest impact on HVAC sizing is now the sensible cooling load from the windows and the latent load from humidity. Selecting a window with a solar heat gain co-efficient (SHGC) of less than 0.3 can reduce your air conditioning requirements by half a ton (or more) on a home. That means a smaller air conditioner and smaller duct sizing to help offset the savings of picking the better windows. It also provides greater comfort to the occupant year-round and additional carbon reduction. Once you have your windows selected, don’t let anybody change them. Then, give this information to the HVAC designer, who needs to be current with the CSA F280-12 sizing standard. It is somewhat alarming that there are still many HVAC designers out there using the old standard. If you are not sure, check out the Master Planning Decision Guide for Natural Gas Mechanical Systems, available from Natural Resources Canada. Use materials that sequester carbon (or low-carbon impact) I love wood. I love the smell of fresh wood and the look of all that lumber creating the skeleton of the homes we build. I also love that wood is a carbon sink and a sustainable construction practice. But there are many more products within a home. Where possible, we are now looking at products with low-carbon impact and that are GreenCircle or GreenTag certified. For example, BASF is now offering a new version of their Walltite (CM01) spray insulation that uses a hydrofluoroolefin (HFO) blowing agent, which has significantly less carbon impact than their current insulation, which uses a hydrofluoro­ carbon (HFC) blowing agent. 31 For a bit more than $1,000 net cost, most builders can get their home to less than 1.0 ACH, simply by filling the big holes, removing some costly steps and using AeroBarrier to air seal their home.

  • 34. BETTERBUILDER.CA | ISSUE 32 | WINTER 2019 Add solar generation Okay, so now we have a home that is pretty much built to net zero-ready. Add the solar panels and you’ve taken another step to reduce your carbon footprint. But what about the carbon emissions during construction? What if we were able to produce the needed energy on the job site with a mobile solar generator station? That’s crazy talk, right? Not so fast. A great number of subtrades are now using an increasing array of battery-powered tools, from hammers, saws and screwdrivers to paint sprayers, mixers and many more. It’s already happening. When we did Project Hope, we supplied the majority of our energy needs with a mobile solar energy station from Anvil Crawler. It came equipped in a 20-foot shipping container, including a battery backup array. It may not meet all of your needs, but for production builders, it is an innovative solution. Conclusion I share this list of ideas to encourage dialogue, in the hope that others will join us on the journey to a lower-carbon economy. By no means is this intended to be the only solution. There are great energy consultants available to help builders find their way, and I encourage industry stakeholders to work together through voluntary programs to move our industry forward. What is missing? Like Lou said, it’s the carrot. To add a carbon tax and not incentivize the needed reductions in our industry is a missed opportunity, and we need to encourage our MPs and MPPs to ensure it is implemented fairly.
