In an earlier blog post titled A Home is Where the HERS is, we wrote about the HERS (Home Energy Rating System) Index. Since then, we have an important update that we wanted to share. On March 17, 2014 the American National Standards Institute (ANSI) approved the HERS Index as the National Standard for Home Energy Ratings of new and existing homes. The index measures a home's energy efficiency by calculating its performance through a number of diagnostic tests that include air leakage and the effectiveness of insulation.
The advent of tax based incentives, energy efficient mortgages, and the incorporation of an energy rating index within the 2015 building code all demonstrate the industry's focus on the significance of energy performance. For more information on the HERS Index please visit their website here.
