HERS Index


Available in Oregon, Washington, Idaho, Montana

The Residential Energy Network (RESNET) Home Energy Rating System (HERS) Index is an industry recognized system by which a home's energy efficiency performance is measured and labeled. It’s also a nationally recognized system for inspecting and calculating a home's energy performance. To calculate a home’s HERS Index Score, a certified RESNET HERS Rater does an energy rating on a home and compares the data against a 'reference home'– a designed-model home of the same size and shape as the actual home, so a score is always relative to the size, shape and type of house tested. The standards, developed by the RESNET, are officially recognized by the federal government for verification of building energy performance for such programs as federal tax incentives, the Environmental Protection Agency's ENERGY STAR program and the U.S. Department of Energy's Building America Program.
