Energy efficiency scores will soon be included on appraisal forms in a handful of states. Builders are applauding the change, saying that will help give more credit for energy-saving features.
The Home Energy Rating System (HERS) Index is a numerical rating system that measures energy consumption compared to a standard house. The standard house has a score of 100. But a house that has a HERS index of 70, for example, would use 30 percent less energy. A home with a HERS index of 130, on the other hand, would consume 30 percent more energy. As such, the lower the HERS score, the lower the energy costs. The HERS score will be added to an existing green-building addendum that appraisers use.
