RESNET® announces that over 4 million homes in the United States have now been rated with a HERS® Index Score! RESNET Executive Director Steve Baden says, “Reaching four million HERS-rated homes is a significant milestone. Moreover, reaching a million HERS-rated in just over three years speaks to the continued upward trajectory of home buyers choosing more energy efficient, comfortable, and healthier homes.”

The HERS Index Score is used by builders, utility companies, real estate professionals, and government agencies after being rated by a certified RESNET Home Energy Professional, to give an estimate of a home’s energy usage and provide buyers/owners with knowledge on how energy efficient that home is compared to others. Heating, cooling, and water heating make up the largest cost (outside of the mortgage loan) of homeownership. The HERS Index Score can also help homeowners by finding energy features of the home and the estimated monthly cost of utility bills.

Since RESNET began tracking HERS-rated homes as part of its National Buildings Registry in 2012, there has been a 126% increase in the number of HERS-rated homes. Big Milestones include:

1 million HERS-rated Homes: 2012

2 million HERS-rated Homes: 2017

3 million HERS-rated Homes: 2021

4 million HERS-rated Homes: 2024

The RESNET Board of Directors have adopted a goal that 1 million RESNET ratings will be conducted annually by the end of 2028. Initiatives to meet this goal include: ESG reporting, tax credits, code compliance, green mortgage back securities, water and carbon efficiency, the build-to-rent market, and veterans’ home loans.
