In 2017 there were 227,840 homes in the United States that were HERS rated and issued a HERS Index Score. This broke the record for the number of homes HERS rated in a year. In 2017 there were 21,257 more homes HERS rated than in 2016.

The average HERS Index Score in 2016 was 62. This is 38% more efficient than a home built as recently as 2006.

RESNET Executive Director Steve Baden commented on the over 227,000 homes HERS rated in 2017, “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.  I expect that this trend will continue.  It is particularly ‑‑encouraging that the average HERS Index Score was 62.  This is 38% more efficient than homes built as recently as 2006 and 68% more efficient than a typical home built in 1970.  I congratulate the energy smart builders, HERS Raters and program sponsors that are leading the trend to mainstreaming high performance homes in the market place.”

To learn what is driving this trend, attend the 2018 RESNET Building Performance Conference.  The RESNET Conference is the “not-to-miss” event on home energy ratings and home performance.  For more information go 2018 RESNET Conference.
