2. Report Summary
St. James Anglican Church is located at 10 Union St., Kingston. It’s a spectacular building with more than 150 years of
history. Our first visit to St. James Church was March 11th
, with a second visit occurring March 24th
. It is the intention of
this report to put forward recommendations to the church elders to improve energy savings and reduce utility cost.
First, a description of the audit process will be put forward. The different zones of the building will be described, along
with wall composition, electrical loads and more. Results of our analysis will be presented through two pie charts: “heat
loss as dollars” and “electrical loads as dollars”. Our recommendations and energy savings estimates will be presented.
Notable estimates are the $900 potential savings with batted insulation in the nave ceiling and $935 potential savings in
parish hall through polystyrene and sprayed polyurethane insulations. Finally, a brief discussion on steam vs natural gas
heat will be communicated.
Appendix A includes additional information and heat conduction properties of walls, roofs, windows and doors. Major
electrical and lighting loads are described in Appendix C. Appendix D lays out a schematic of the steam distribution
system. Appendix E presents historical electrical utility data in two 3-D surface charts. Appendix F presents a utility
consumption chart. Appendix G presents a temperature data log chart. Appendix H provides further information on the
process of utility reconciliation. Finally, Appendix I presents a chart of logged steam temperature.

Report
The Blower Door Test
A “Blower Door Test” uses a large fan to depressurize a building resulting in outside air streaming in through cracks
and air gaps. It is an extremely effective method for identifying major sources of heat loss and air leakage in a building.
RetScreen
The software used to model the church is called RetScreen. The program takes user inputted measurements to
construct a mathematical model with equivalent characteristics to the target building. It allows for detailed energy and
financial analysis. We further improve model accuracy by reconciling historical NASA weather data with utility data.

3. Building Description
Four main zones divide the building: the nave, Roger’s room, parish hall and the office/nursery area. This section of the
report will describe the construction materials of each zone, lighting, electrical loads and the heating system.
Zone 1: The Nave
Below grade walls on the North and East sides are of 24” thick limestone
construction. The above grade exterior walls are of 26” thick limestone
construction. Above grade interior walls are of lath and plaster construction,
separated by a 2” air gap. The West and South walls are of similar construction,
with the exception of some altar sections which are 24” limestone above grade with
no lath and plaster.
There are three ceiling types: nave flat, nave sloped and altar sloped. The nave flat
ceilings are insulated by 6” loose fiberglass between rafters, with lath and plaster
interior. The nave sloped sections are similar with the critical exception of not being insulated. The sloped alter section is
similarly uninsulated, with a hidden air cavity concealed by interior lath and plaster.
Nave lighting is provided by several types of fixtures. Ten chandeliers hang from the ceiling, each with one CFL and ten
LED bulbs. Ten LED pot-lights illuminate the areas underneath the flat ceiling sections. A string of 18 LED lights are hung
around the sanctuary arch. Of note were ten high wattage halogen luminaires that were inoperable on the day of the
audit. Additional electrical loads include musical instruments, ceiling fans, a small sound system and computer setup.
Zone 2: Roger’s Room
Above grade walls in the Roger’s room area were of 26” limestone construction,
with an air gap of 2” and lath and plaster interior. Below grade walls were a 24”
thick mixture of poured concrete and limestone. The flat ceiling in Roger’s room
was insulated with 7 inches of loose fiberglass. The flat ceilings in the hallway
and office sections were insulated with 6 inches of loose fiberglass.
Lighting here consists of 31 T8 fluorescent light bulbs of low usage. Entrance and
vestibule lighting is included in this zone, with a single T12 and incandescent
bulb, both with high usage. There are no other electrical loads within this zone.
Zone 3: Offices/Nurseries
This building section has two floors with only East and South exterior walls.
Above grade walls in the offices and nurseries were of 8” concrete block
construction, with an air gap of 0.5 inches and exterior clay brick of 3.5 inches.
The flat ceiling in these spaces has an R-value of approximately 20.
Lighting in this zone is provided by a variety of T8, T12, CFL and incandescent
bulbs. The most notable load is 24 T8’s bulbs of high usage in a recreation area
on the second floor. Other electrical loads in these spaces include computers
and ceiling fans.
Please refer to Appendix C for a schematic of the building zones.

4. Zone 4: Parish Hall
Parish hall is a unique half-octagonal structure consisting of two floors with
a basement. Above grade walls consist of 9” limestone, an air gap and lath
and plaster interior finish. Foundation walls consist of 16” poured concrete
and 9” limestone. Below grade walls are 24” thick poured concrete. Only
the South facing above grade walls have an additional exterior wall finish of
3.5 inches of clay brick. Parish hall flat ceilings are insulated by 6 inches of
loose fiberglass and one inch of lath and plaster.
Lighting for these spaces is provided by many CFL, T8 and T12 bulbs. Large
lighting loads include the six T8’s in the kitchen and six T8’s in the
dishwasher area. Of note is the twenty one 23 watt CFL bulbs on the second floor of the hall; the client was unsure of
their duty cycle. He reported they may be on a separate motion sensor or switch in another location.
The most demanding electrical loads in this zone are unquestionably the two hot water heaters in the basement.
Significant other loads exist in the kitchen, such as the fridge, freezer, coffee machine, stoves and other appliances.
Additionally, three ceiling fans hang in the main hall.
Steam Heating System
The building is heated through underground steam lines supplied from Queen’s
University. The saturated vapour is supplied by steam lines throughout the building
to cast iron radiators. After heat is delivered, the condensed steam returns along
condensate lines to exit the building. Each zone has its own separate steam line
with independent thermostat to regulate flow, and thus temperature.
Please refer to Appendix D for a schematic of the steam distribution system.
Please refer to Appendix I for a chart displaying logged steam temperature.
Results of Analysis
Total Yearly “Heat Loss as Dollars” is $21,810
This compares to the modeled yearly steam
cost of $19,260.

5. Total Yearly “Electrical Loads as Dollars”
cost is $4428.00

6. Recommendations
Heat Loss; Air Leakage Solutions
As shown in the “Heat Loss as Dollars” chart, air leakage and conductive heat loss through walls accounts for the vast
majority of energy cost in this building. Air leakage and excessive heat loss are both symptoms of a single cause:
insufficient insulation. The worst wall is the above grade 26” limestone wall in zones one and two, with a yearly heat
cost of $1327. The above ground brick wall in zone three and the above ground 9” limestone wall in zone four have heat
costs of $923 and $917, respectively. The sloped ceiling in the nave costs an incredible $1067 per year to heat. It is
hoped that by improving insulation in these four spaces, significant energy savings can be accrued.
It is our recommendation that insulation be improved in all areas mentioned above,
starting with the nave walls. By filling the two inch air gap with sprayed polyurethane
foam, the wall R-value would be increased from 6.97 to 15.78; more than double. This
would save an estimated $741 in heating cost, nearly halving the heat cost for that wall
type.
Next is the above ground brick wall in zone three. By
filling the half inch air gap with sprayed polyurethane
foam, the wall type R-value would increase from
3.294 to 5.497. This would yield an annual energy
savings of $370. If an additional two inches of
polystyrene insulation was installed on the interior of this wall type, the R-value
would increase to 15.44 and annual savings would increase to a total of $726.
The above ground 9” limestone wall in parish hall currently costs $917 each year
to heat. The first upgrade step would be to fill the half inch air gap with sprayed
polyurethane foam. This would increase the R-values of the North, East and West
walls from 3.842 to 6.045. The South wall R-value would be increased from 4.202
to 6.406. Savings accrued from this upgrade would be $445. If an additional two
inches of polystyrene insulation was added to the interior of these walls, the total
savings would increase to $935. Notice how this savings estimate is higher than
the modelled heat loss cost of the wall ($935>$917). That is because this upgrade
not only addresses conductive heat loss through the wall, but also takes a bite out of the “zone 4 air leakage” pie.
It was astonishing to learn that the slopped ceiling in the nave was completely
uninsulated, as seen in the picture to the right. That would explain why heat loss cost is
so excessive here; $1067 per year. In is our strong recommended that this oversight be
remedied as soon as possible. The simple addition of just eight inches of fiberglass
batted insulation would take the current ceiling R-value of 5.117 up to 32.589, a nearly
six fold increase. This would yield savings of $900 even. Installation of this material
would not be a difficult, nor time consuming task. It is our strongest recommendation.
Please remember that when multiple energy upgrades are implemented simultaneously, the cumulative energy savings
will not be as high as the estimates for individual upgrades. The recommendations above are intended to offer the client
several options, of which he may choose only one to implement. If the client indeed wishes to proceed with several or
even all recommendations, we will be happy to provide an adjusted energy savings estimate free of charge.

7. Natural Gas Hot Water Tank
It is currently estimated that $1711.92 is being spent every year on hot water for the church. This is
provided by two hot water tanks of 12kW and 3.5kW. The high cost is due to the tanks being
electrically heated, which is an expensive method. With the rising electricity prices in Ontario, it’s
expected that this yearly cost will increase. It would be ideal to find a more inexpensive solution.
One method would be through natural gas. A single tank of 75,000 BTU/h should be adequate to
replace the two electric tanks. (15.5kw*3412Btuh/kw / 70% efficiency = 75,550 Btu/h requirement)
The duty cycles of the existing electric tanks are quite low (5%-12kw; 18%-3.5kW), so it may be
possible to substitute them with a natural gas tank of equivalently less heat capacity. The model
pictured to the left is a Rheem 75k BTU/h unit, available at home depot for $1228. The Energuide
estimate of yearly energy cost is $670, a substantial savings from current electric cost.
An additional possibility exists in the form of solar hot water. Photovoltaic panels could provide
some power to the existing electric heater, with supplementary power being drawn from the mains.
This would be a relatively inexpensive modification to the current setup. If the client so desires, we
could investigate this option further to determine the potential savings of an optimized system.
Coffee Machine Timer
Our data-logger recorded an average daily usage of the coffee machine of 2.7kWh.
Amazingly, this was nearly double the electricity usage as the stand-up freezer. We
were told that the coffee machine was always hot and gurgling, even when switched
off. Our assumption is that the machine is seeking to maintain a constantly high water
temperature for quick brewing when called for.
This continual heating is an unnecessary waste of energy. There is no need for this
during the night or when the kitchen is unoccupied. The electrical analysis shows a
yearly energy cost of nearly $150, which is not insignificant.
This situation can be easily solved with a simple timer that would effectively unplug the
machine during the set time period. If even a marginal 10% reduction in electricity
consumption could be achieved, the timer would pay for itself within a year. I would first recommend setting the timer
to disconnect the machine from between the hours of 10pm and 5am, with further reductions were possible. The timer
is available at Canadian Tire for the cost of $15.
Discussion and Analysis of Steam vs Natural Gas Heat
As it is now, Queen’s University provides steam to the church free of charge. If that situation ever were to change, it
might be beneficial to have some information regarding alternative heating options.
The current value of steam provided last year was $18,252.08 (from utility bill). Adjusting for weather considerations,
the reconciled cost of steam was $19,260.37, which was inputted into the software model as $19,216. If the entire heat
load of the building was to be provided by a 90% efficient natural gas boiler, the model predicts a fuel cost of $19,818.
(At a rate of $0.44/m3
) The percentage difference between current reconciled steam cost and predicted natural gas cost
is 3.0%. This is a staggeringly slight difference.
It is therefore our conclusion that switching to natural gas would not yield any considerable savings over steam.

8. Appendix A: Wall and Ceiling Types; R-Values
Please note that through the following tables I was able to compute composite R-values for all the different wall types in
the church. These composite R-values were inputted into Retscreen in the “above grade wall” field.

17. Appendix D: Steam Distribution System
The steam system has four branches off the main building supply. The branches each serve the four building zones:
nave, nurseries/offices, Roger’s room and parish hall. Four independent thermostats control steam flow to each zone.

21. Appendix G: Temperature Data Log Chart

22. Appendix H: Utility Reconciliation of Steam and Electricity
Steam Reconciliation
Initial variance between historical and modelled steam consumption:
To reduce the variance, the modelled air change rate was changed from 0.363 ac/h to 0.465 ac/h.
The resulted variance between modelled and historical steam consumption was reduced to 0%.

23. Electricity Reconciliation
The initial variance between the historical electrical utility data and the modelled usage is quite low, 4%.
The modelled usage was first tabulated in a separate Excel file, with the final total being inputted into RetScreen:
The modeled usage was based on estimates provided from the client and two weeks of data logging. The client must be
assumed to be correct in his estimations and the logged data must be assumed to be representative of yearly data.
However, if that were entirely accurate, we would have perfect correlation between utility and modelled data. The
model is over predicting electricity usage by 4%. This may be due to an over estimation of usage during the summer
months, which our 3D surface chart shows drops off considerably. Consider the chart:
There is a reduction of usage of approximately 50%
during the months of July and August. During the
summer, the Church must have very few programs
active, resulting in much lower usage. The model does
not account for this: it assumes the inputted electrical
and appliance duty cycles remain constant throughout
the entire year. It would therefore be over-predicting
electricity usage, possibly by accounting for the 4%.
For the purposes of upgrades and recommendations,
the current modelled electricity usage will be used.
However, it will be noted that any calculated savings to
be expected is based on a model made without enough
year-long data to be 100% accurate to historical usage.
Any recommendations made to lighting and electrical systems must therefore be taken with a 4% grain of salt.

24. Appendix I: Steam Temperature
While steam supply remains at reasonable and
predictable temperatures for the most part, there are
several recorded anomalies. Consider the following:
Date Steam Supply Temp (°F)
March 24th
, 2:23 pm 797
March 16th
, 7:41 am 426
March 24th
,
2:26pm to 2:30pm
Between 345 and 386
March 11th
, 12:56pm 398
The average supply temperature, found through an
excel trend-line, was seen to be 230°F. Why then do we
see large spikes in temperature of double or even triple
that amount?
The answer may be that in those instances the
delivered steam was not saturated, but superheated.
Saturated steam is normally used for heat delivery for
its high energy content. Energy is harness though the
change of state from vapour to liquid, and returned
through the condensate line. Superheated steam is
heated above its boiling point, and can be cooled
without changing its state back to liquid. Superheated
steam is high temperature and high pressure, but with a
much lower energy content than in its saturated state.
The bottom line is that if superheated was being
delivered as high as 800°F in some instances, this would
cause a considerable spike in pressure. The system have
not have been designed to be able to cope with these
occasional pressure spikes.
It may be of value for the client to investigate this
matter, to ensure there is no danger to his system. A
possible diagnostic method may be to setup a
temperature logger on the supply steam line, with a
video camera focused on the pressure gauge. After an
appropriate interval, the temperature log could be
consulted, temperature spikes noted and the time-
stamped footage would indicate how high the steam
line pressure reached. It might even be possible to set
the camera to record precisely in tune with the logger
interval to save on memory space.
It would be of benefit to the client to know exactly how
high his supply pressure is peaking, and if it constitutes
a potential danger.
