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

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

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;

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

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
