Renovations & Additions

How Incentives Are Calculated

How Incentives Are Calculated

Incentive eligibility depends on whether the home meets minimum energy savings requirements. Incentives are determined by the amount of electric savings, fuel savings (natural gas, propane, or oil), and overall performance compared to the program baseline. Participating homes are also eligible to receive no-cost LED bulbs.

Here's how it works:

 

  • 1 Pre-construction Home. During an initial site visit, Mass Save calculates how much energy your home currently uses.
  • 2 Baseline Home. Using advanced software, Mass Save calculates energy savings for both the renovated portion of the home and the new addition.
  • 3 Post-construction Home. Mass Save calculates how much energy your updated home uses.
