Number of HERS-Rated Homes Grows in First Three Quarters of 2021

Despite the continued disruptions caused by the COVID-19 pandemic, the supply chain, and labor shortages, the demand for the Home Energy Rating System (HERS) grew steadily in the first half of 2021, according to the Residential Energy Services Network (RESNET).

In the first six months of 2021, there were 150,894 homes rated and entered into the RESNET registry. This compares with the 145,961 homes that were rated during the same period in 2020, which equates to a 4,933-home difference.

“The growth of the demand for HERS ratings in the first half of 2021 reflects the continued resiliency of the HERS community and the demand for healthy, energy-efficient homes,” says Steve Baden, RESNET executive director. “We believe this demand will continue now and after this time of disruption in the building industry.”

With data through September, the organization now reports the total difference in the number of homes entered into the registry between 2020 and 2021 is 12,643.

The increase in HERS rating activity can in part be explained by home building having been designated an essential activity by most states during the pandemic and the growing demand for housing, due in part to lifestyle changes, low mortgage interest rates, and additional factors.
