About Home MPG
Home MPG, an initiative within Mass Save®, provides homeowners with their home's "miles per gallon" energy performance rating, called an "energy performance score" or EPS. By helping people better understand their home's energy use, Home MPG helps people make smart decisions about implementing improvements that make the home more energy efficient and comfortable.

Home MPG covers all homes in Belchertown, East Longmeadow, Hampden, Longmeadow, Monson, Palmer, Springfield, and Wilbraham that are eligible for home energy assessments sponsored by the Mass Save initiative.

In addition to the no-cost energy assessment, efficiency recommendations, and financial incentives already offered through Mass Save, Home MPG provides the following enhancements:
  • A home "energy performance score" (EPS) - similar to a miles-per-gallon (MPG) rating for cars - that indicates a home's energy use and cost to operate irrespective of occupant behavior. The EPS scorecard is provided both before and after making improvements to illustrate energy savings associated with those improvements.
  • Thermal images (for some homeowners) that highlight energy saving opportunities in the home.
  • A convenient online system that allows homeowners to view their EPS and recommended improvements, read and write reviews of energy professionals, and connect with contractors who can do the work. (Homeowners can still simply call Mass Save at 866-527-SAVE(7283) to schedule a no-cost Home Energy Assessment and efficiency improvement work.)
Home MPG is funded by a grant from the U.S. Department of Energy. For more information, visit HomeMPG.net or contact Catherine Ratte at cratte@pvpc.org, Elise Avers at elise.avers@state.ma.us, or Alissa Whiteman at alissa.whiteman@state.ma.us.
About EPS
The Energy Performance Score (EPS) is an energy performance asset rating tool for both new and existing homes. The EPS is a metric that reflects the energy and carbon impact for a home and allows for home-to-home comparison. The Energy Performance Score is a "MPG" or miles-per-gallon style rating or label for the built environment. EPS has three components: the assessment, the scorecard, and the recommendation report. Together, these components guide homeowners toward cost-effective energy improvements. The scorecard shows the EPS both "before" and "after" making recommended improvements, thus helping homeowners "see" the impact of the recommendations.
