The RESNET HERS® Index is the industry standard by which a home’s energy efficiency is measured Across the nation state and local governments are adding a HERS® Index Score target as a performance compliance option to their building energy codes. To aid in the deliberations on what an appropriate HERS® Index Score would be for an performance path to an energy code, RESNET commissioned a study by the Florida Solar Energy Center. The study projects what HERS® Index Scores equates to the 2006, 2009 and 2012 versions of the International Energy Conservation Code (IECC) for typical residences across representative U.S. climates. This analysis will serve as an invaluable tool for local jurisdictions in assigning a HERS® Index Score for their energy codes and in the discussion of incorporation a HERS® Index Score in a future version of the IECC.
