Top States in Production of HERS® Index Scores

Jun 21, 2022

Each year more than one-fifth of all new homes built in the U.S. are rated for their energy efficiency using the Residential Energy Services Network’s (RESNET®) Home Energy Rating System (HERS) Index. Annually RESNET tracks the trends across all homes receiving a HERS. The analysis for 2021 has been completed.

In 2021, certified RESNET HERS Raters rated more than 313,000 homes. This represents a 4 percent increase over the number of ratings in 2020 and marks the ninth straight year-over-year increase in HERS ratings.
