Bring Home Energy Scores to your Jurisdiction

The Bay Area pilot is now a statewide program!

Since 2018, BayREN, a collaboration of the nine Bay Area counties and the Association of Bay Area Governments, has been leading the Home Energy Score program for the Bay Area. Recently, BayREN has been approved by the California Public Utilities Commission to launch a statewide Home Energy Score program beginning in 2026. 

Over the next two years, the Home Energy Score California will be conducting outreach and gathering feedback from stakeholders to inform program design. Please review the FAQ to learn more and feel free to contact us with questions and suggestions! Check back here for information on future opportunities to get involved.

HES Report Example

What is the Home Energy Score?

The Home Energy Score (HES) is a rating system developed by the US Department of Energy which provides a standardized rating of a home’s energy efficiency. The report includes the home’s score ranging from 1 to 10, an estimate of energy usage and utility bills, and custom recommendations to increase your home’s energy efficiency.

Trained assessors analyze the home's heating and cooling systems, water heating, insulation, duct sealing, and more, to create a report that enables a standardized comparison across different geography, and provides homeowners, buyers, and renters credible information about a home’s energy assets.

The Home Energy Score California program will:

  • Train energy assessors that will serve your community, and ensure strong quality control.
  • Deliver the program and customize recommendations for home improvements based on the score.
  • Provide rebates for residents to receive a HES and connect them to resources to make energy efficiency upgrades.

Benefits for Local Governments

  • Aligns with your Climate Action Plan goals
  • Helps community members save money on their energy bills
  • Provides consumers with transparent, comparable energy efficiency information
  • Choose how much you want to customize and promote the HES program in your jurisdiction – Home Energy Score California will provide marketing materials and do the rest!

HES and Other Local Policies:

  • HES can align with policies related to energy audits or disclosure in your Climate Action Plan
  • Voluntary programs help homeowners understand their home’s energy assets and how to make improvements
  • If desired, a jurisdiction may layer on a mandatory HES requirement. Examples of these policies can be found in Berkeley, CA, Piedmont, CA, Portland, OR, Austin, TX, Minneapolis, MN, and more.
