Built for Better Living
This achievement represents far more than a number. Behind 5 million HERS® Rated homes are millions of families benefiting from homes designed for greater comfort, lower utility bills, improved affordability, and long-term value.
Reaching 5 million HERS Rated homes would not have been possible without the hard work and dedication of HERS Raters, Rating Field Inspectors, and HERS Modelers nationwide. They have helped make the HERS Index the nationally recognized, widely adopted, and trusted measure of home energy performance it is today.
For homeowners, a HERS Rated home provides more than an energy score. It offers insight into how a home will perform — helping families better understand energy use, anticipate utility costs, and enjoy the benefits of a more efficient and comfortable living environment.
Heating, cooling, and water heating are among the highest ongoing costs of homeownership after the mortgage. Homes that are designed and verified for efficiency can help reduce monthly utility costs while supporting greater comfort and durability over time.
