Home Energy Rating System
(HERS) Ratings
developers looking to meet code compliance, enhance energy performance, or

What is a HERS Rating?
A HERS Rating is the industry standard for measuring a home’s energy efficiency.
Developed by RESNET, this nationally recognized system evaluates how much energy a home is expected to use and assigns it a HERS Index Score the lower the score, the more energy-efficient the home.
