What is a HERS Rating?

A HERS Rating (Home Energy Rating System) measures the energy efficiency of a home and is used to verify compliance with the Massachusetts Stretch Energy Code.

The HERS Index is the national standard for measuring residential energy performance and is commonly required for new construction homes in Cohasset MA.

Learn more about the HERS Index:

Typical HERS Score Scale

  • 100 HERS Score – Standard new home

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

  • 40–50 HERS Score – High-performance home

  • 0 HERS Score – Net Zero Energy home

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