For a breakdown of the number of homes HERS rated in 2022 and the average HERS Index Score by state go to 2022 HERS Activity by State. For a breakdown of the number of homes HERS rated in 2022 and the average HERS Index Score by IECC Climate Zone go to 2022 HERS Activity by Climate Zone.

Of greater significance is the energy bill savings that the families who purchased these HERS-rated homes are receiving. It is calculated that the 2022 HERS-rated homes will net over $253 million in annual energy bill savings, as compared to the HERS reference home.

In addition, it is calculated that the homes that were HERS rated in 2022 will reduce carbon dioxide emissions by over 1.5 million tons annually. These savings will, according to the EPA calculator, equate to over 3.1 million passenger vehicles being taken off the road for one year.

"Homebuilders are increasingly seeing energy efficiency as a major selling point for buying a new home. To take advantage of this opportunity, builders across the nation are presenting their homes' energy performance in a way that every home buyer can understand, the home's HERS Index Score," commented RESNET Executive Director Steve Baden on the 337,962 homes HERS rated in 2022. "I expect that this trend will continue. It is particularly encouraging that the average HERS Index Score of homes HERS rated was 58. This is 42% more efficient than homes built as recently as 2006 and 72% more efficient than a typical home built in the1970s.  I congratulate the builders, HERS Raters, and RESNET strategic allies that are leading the trend to mainstream high-performance homes in the marketplace.”

“RESNET, however, is not content with the current market share of HERS-rated homes. In 2023, RESNET is launching its initiatives that will include increasing the demand for HERS Raters services through new opportunities in energy code compliance, water efficiency rating, rating the installation of HVAC systems, the new RESNET Carbon Index and the emergence of ESG reporting and green bond mortgages based on HERS Ratings," he added.
