Home MPG (miles per gallon) was a community-based energy saving initiative within the Mass Save® home energy services program. Residents in these communities could receive a no-cost home energy assessment, plus bonus financial incentives to help with installing insulation and heating or hot water system upgrades. Special incentives were offered to those properties that had been damaged by the June 1, 2011 tornado. Home MPG offered a home energy performance score (similar to a vehicle miles per gallon rating) and, for most homeowners, thermal imaging analysis that visually depicts areas of heat loss in their homes. 

In 2012, Pioneer Valley Planning Commission partnered with Center for EcoTechnology and Honeywell to perform audits and retrofits for residential dwellings with one to four units in Belchertown, East Longmeadow, Hampden, Longmeadow, Monson, Palmer, Springfield, and Wilbraham.  By the end of the program, over 600 total audits and 83 total upgrades had been completed.
