Last year, 227,840 homes were HERS rated and issued a HERS Index Score, a 10 percent increase from 2016. The average HERS Index Score in 2017 was 62, which 38 percent more efficient than a home built as recently as 2006.
Texas had the greatest number of homes receiving a HERS Index Score last year (44,680), followed by Arizona (20,599), Florida (15,996), North Carolina (15,545) and Colorado (11,340). At the other end of the spectrum, Vermont had the fewest (43), followed by Maine (46), Montana (49), Minnesota (51) and Hawaii (52).
“Homebuilders are increasingly seeing energy efficiency as a major selling point for buying a new home,” said RESNET Executive Director Steve Baden. “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. I expect that this trend will continue.”
