Your Score

An assessor uses a formula developed by the U.S. Department of Energy (DOE) to score your home’s energy use on a scale of 1 to 10. It estimates home energy use, associated costs, and provides energy solutions to cost-effectively improve your home’s efficiency. 

Home Energy Score® is a program of the U.S. Department of Energy. StopWaste is a Home Energy Score® partner serving the San Francisco Bay Area in collaboration with BayREN. 

Cost & Rebate Process

HES costs vary depending on factors, such as location and home size. There are three steps to get your rebate.

  1. Find an assessor near you by searching our database
  2. Talk to the assessor about the $200 BayREN rebate and ask if there are any additional rebates.
  3. Book your HES and get your report and score.

Assessors will have the rebate form on the date of your appointment. They will walk you through the application process.
