What Is a HERS Rating?

A HERS Rating (Home Energy Rating System Index) measures the energy efficiency of a home compared to a standard reference home built to code.

The rating follows national standards developed by RESNET.

The lower the HERS Index score, the more energy efficient the home.

Typical HERS Index ranges include:

• 100 – Standard new home built to minimum code

• 70–55 – High-efficiency home

• 45–42 – Typical Massachusetts Stretch Code targets

• 0 – Net Zero Energy home

HERS ratings help verify energy performance and confirm compliance with modern building energy codes.
