The Residential Energy Services Network (RESNET) announced that 277,480 homes were scored on the Home Energy Rating System (HERS) Index last year, a 10% increase from 2016.

RESNET’s HERS rating is a nationally recognized standard of home energy efficiency. 21,257 more homes were HERS-rated last year than in 2016, according to RESNET, breaking the organization’s record for number of ratings given in a single year. The average HERS Index score for homes rated in 2017 was 62, which RESNET says is 38 percent more efficient than some homes built in 2006 and 68 percent more efficient than a typical home built in 1970.

"Home builders are increasingly seeing energy efficiency as a major selling point for buying a new home,” says 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.”

According to RESNET, Texas is the state with the highest number of HERS-rated homes at 44,680, followed by Arizona with 20,599 homes. Florida is third with 15,996 HERS rated homes followed by North Carolina with 15,545. The number of homes scored on the HERS Index varies by climate zone and state.
