The Gold Standard for Home Energy Efficiency

For Home Energy Efficiency

Understanding the HERS Index

The Home Energy Rating System (HERS) index is the industry 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.

A certified RESNET Home Energy Rater assesses the energy efficiency of a home, assigning it a relative performance score (the HERS Index Score), The lower the number, the more efficient the home. The U.S Department of Energy has determined that a typical resale home score 130 on the HERS index while a home built to the 2006 international energy conservation code is awarded a rating of 100.


A home with a HERS index score of 70 is 30% more energy efficient that the RESNET Reference Home.

A home with a HERS index score of 130 is 30% less energy efficient than the RESNET Reference Home.


To calculate a home’s HERS Index Score, a certified RESNET HERS Rater does an energy rating in your home and compares the data against a reference home – a designed-model home of the same size and shape as the actual home, so your score is always relative to the size, shape and type of house you live in.
