HERS Index: The Home Energy Rating System

The HERS Index is a national standard for measuring the energy efficiency of homes. It is a number on a scale of 1 to 100, with 1 being the least efficient and 100 being the most efficient.

A HERS rating can be considered the "miles per gallon" of a home. Just like when shopping for a car, you can use this standard or measure to compare different homes in terms of energy efficiency. You can search to find the rating of specific addresses on RESNET's registry.

The HERS Index is calculated by a HERS Rater, who is a qualified professional who has been trained to assess the energy efficiency of homes. The HERS Rater will conduct a thorough evaluation of your home, including:

The insulation levels in the walls, roof, and attic
The efficiency of the windows and doors
The type and age of the heating and cooling system
The air sealing of the home

The HERS Rater will then use this information to calculate your home or business's HERS rating.

What Does a HERS Rating Mean?

A HERS rating of 70 is considered average, while a rating of 80 or higher is considered energy efficient. Homes with a HERS rating of 60 or lower are considered to be inefficient and may qualify for government rebates and incentives.

How Can You Improve Your Home or Business's HERS Rating?

There are a number of things you can do to improve your home or business's HERS rating, including:

Increasing the insulation levels in the walls, roof, and attic
Replacing old, inefficient windows and doors with newer, more energy-efficient models
Upgrading your heating and cooling system to a more efficient model
Air sealing your home to prevent air leaks
