What is a HERS Rating?

A HERS Rating (Home Energy Rating System) is the nationally recognized system used to measure the energy efficiency of residential buildings.

The rating is used across Massachusetts to verify compliance with the 2021 International Energy Conservation Code (IECC) and the Massachusetts Stretch Energy Code.

Learn more about HERS Ratings:

The HERS Index Score compares a home’s efficiency to a standard reference home.

Typical scoring scale:

  • 100 HERS Score – Standard new home

  • 70–55 HERS Score – Typical Massachusetts Stretch Code target

  • 40–50 HERS Score – High-performance home

  • 0 HERS Score – Net Zero Energy home

Lower scores indicate better energy efficiency and lower utility costs.
