“It is a capital mistake to theorize before one has the data.”

Arthur Conan Doyle


Details make the difference to builders and their customers, really to the whole new home construction industry.

Trends emerge when one studies HERS rating details over a large national dataset and over time.

What kind of theories can we draw from data in “Trends in HERS Rated Homes, 2022”?

RESNET’s Program Director Ryan Meres joins us to “crunch the numbers” in HERS rating trends for 2021. The data is compiled from the rating providers' data files.


We learn about trends in index scores and the basic characteristics of HERS-rated homes, for example, the number of bedrooms, conditioned floor area, annual energy costs, and energy savings.


The report also reveals summary data on foundation types, insulation, window U-Value and SHGC, envelope air leakage rates, ventilation types, heating, cooling, and water heating equipment, and the use of Solar PV on HERS rated homes.


We get an overview of climate zone and regional data, including states and cities that lead the pack in the number of HERS-rated homes. Ryan also shares some data highlights, as well as the percentage of new homes in the state that receive ratings, noting some of the possible reasons for the way the data plays out.


Members of the RESNET Suppliers Advisory Board get the first look at the report and can benefit from custom reports. Learn more about joining the SAB here:


Look for an announcement in the RESNET newsletter regarding the final report “Trends in HERS Rated Homes, 2022 which will be published in Mid-June 2022.
