What is a HERS Rating?

A HERS Rating (Home Energy Rating System) is the nationally recognized method for measuring a home’s energy efficiency. It is widely used across Massachusetts to verify compliance with the 2021 International Energy Conservation Code (IECC) and the Massachusetts Stretch Energy Code.

• https://www.energy.gov/energysaver/home-energy-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 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 operating costs.
