Home Energy Rating System (HERS) - Trinity Homes
HERS Energy Rating

What is HERS Index?

The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance.

How does the HERS Index work?

A certified Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score. The lower the number, the more energy efficient the home.

An energy efficient home conforming to the 2004/2006 International Energy Conservation Code (IECC) has a HERS Index Score of 100. This means homes with lower scores are more energy efficient while those with higher scores are not energy efficient. The U.S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index.
