2. Helping Massachusetts Municipalities Create A Greener Energy Future
20% Energy Reduction
 Reduce energy use by 20% in 5 years
 20% is not the same for all communities
– Some just starting with efficiency
– Some think they can’t make 20%

Annual Progress Reports
 GCs report annually on energy use
and energy projects for Criterion 3
 Many GCs report energy use
directly through
 FY2012: Data for 44 Green
Communities was considered
complete in time for this
presentation

8. Helping Massachusetts Municipalities Create A Greener Energy Future
Common Energy Reduction Challenges
 Limited staff capacity
 Most Green Communities focus on
buildings
 Vehicles are a challenge
 Baseline year selected was too early
– GC thought had done enough projects
recently to make it worth it, but in reality
shortened 5-year timeframe too much
– Baseline year change allowed once, must
be formal request, contact your Regional
Coordinator

9. Helping Massachusetts Municipalities Create A Greener Energy Future
Harvard – Buildings @ 32% Reduced
 Bromfield High School:
– Boiler hot water VSDs, pneumatic controls
conversion, DCV, BAS upgrade,
retrocommissioning, RTU fan VSDs, lighting
– $127k in utility incentives towards $300k total
cost; annual savings $108k and 32% energy
savings
 Hildreth Elementary School:
– Lighting, convert to gas, replace boiler, boiler
hot water VSDs, DDC
– $91k GC designation grant funds plus $49k in
utility incentives towards $216k total cost;
annual savings $32k and 42% energy savings
 Town buildings
– Lighting, boiler at fire station used $10k in GC
grant funds plus $20k in utility incentives
towards $38k total cost; annual savings $8k
– savings $32k and 42% energy savings

Harvard Press, 10/14/2011
 Using remaining $88k in GC designation grant funds
on more boilers, insulation, air sealing, recommissioning in town
buildings

Easthampton: Streetlights @ 20% Reduction
 469 streetlights converted to LED
 This is approximately 1/3rd of lights
in town
 Saved 20% of the streetlight
energy overall
 Used GC designation grant and
incentives from WMECO towards
total project cost ≈ $222,000
 Projected savings of $23,735 from
175,000 kWh/year reduced
 Done in 2011, LED prices have
dropped significantly during this
project and even more since

Vehicle Efforts
 Incorporation of Global Positioning System (GPS) in
water department vehicles – Cambridge @ 10%
reduction
 “Fuel-efficient vehicle replacements for both non-
exempt and exempt vehicles; junking gas-guzzlers”
– Melrose @ 8% reduction
 2012 Ford Escape MP replaces 2001 Ford Contour
for Buildings Dept Inspectional Vehicle – Acton @
7% reduction
 2011 Ford Escape replaces 1996 Jeep Cherokee;
2013 Ford Explorer replaces 2002 Jeep Tahoe -
Mashpee @ 4% reduction

12. Helping Massachusetts Municipalities Create A Greener Energy Future
Thinking Outside the Box with Vehicles
 Downsize your vehicles – will a smaller vehicle do?
 Change your fuel type – electric vehicles
– Massachusetts Electric Vehicle Incentive Program
(MassEVIP)
 Behavioral program? Competition?
 Tracking and GPS required

13. Helping Massachusetts Municipalities Create A Greener Energy Future
Athol: Water & Sewer @ 6% Reduction
13
 12 ECMs at 9 sites
 Addressed building envelope
at all 9 sites
 VSD for pumps – main source
of savings at 285,000
kWh/year and $30,000/year
 Used utility incentives of
$23,500 towards total cost of
$68,500
 Leaks in FY11-FY12 offset the projected energy savings
from the VSDs
 2 new propane furnaces for well building funded through
GC designation grant of $13,600; annual savings of $3,500
and 1,100 gallons of propane
