The good news for 2024 is that the number of homes that was energy rated and received a HERS® Index Score in 2024 continued to break historical records. In 2024 there were 436,798 homes HERS rated in the country. This is 78,820 more homes that were entered into the Registry during the same time in 2023 (an 18% increase). 2023 was a record year in terms of the number of homes HERS rated. The 2024 HERS Ratings pushed the total number of homes HERS Rated in the U.S. to over 4.4 million. The average HERS Index Score in 2024 was 55. This is 2 points lower than the average Score in 2023. The ten leading states in terms of homes receiving a HERS Index Score in 2024 were: The top 5 states with the lowest average HERS Index Scores in 2024 were: For a breakdown of the number of homes HERS rated in 2024 and the average HERS Index Score by state go to 2024 HERS Activity by State. For a breakdown of the number of homes HERS rated in 2024 and the average HERS Index Score by IECC Climate Zone go to 2024 HERS Activity by Climate Zone. Of greater significance is the benefits of the homes that were HERS rated in 2024. Foremost is energy bill savings that the families who purchased these HERS rated homes are receiving. It is calculated that the 2024 HERS rated homes will net over $398 million in annual energy bill savings for families living in these rated homes, as compared to the HERS reference home. In addition, there is an environmental benefit. It is calculated that the homes HERS rated in 2024 will reduce carbon dioxide emissions by over 1.5 million tons annually. These savings will, according to the EPA calculator, equate to 326,400 passenger vehicles being taken off the road for one yea. RESNET® Executive Director Steve Baden lauded the 2024 accomplishment. Having the number of homes HERS rated increase by 18% over the past record while the energy performance of homes improved at the same time is significant and a credit to the HERS industry, the builders who construct the rated homes and our industry partners.” “RESNET, however, is not content with resting on our laurels. In 2024 the RESNET Board of Directors adopted the audacious goal of having a million homes RESNET rated annually by the end of 2028. In the next few years, the RESNET team will be focused on meeting this goal while enhancing its effort to be the gold standard of quality by the housing industry.”
