HERS, or home energy rating system, rates the efficiency of a home and measures it against similar sized-homes in the area. With HERS, the lower the score, the more efficient the home. Scores can range anywhere from 0 to over 500, with zero being the best possible rating. Visit the Residential Energy Services Network to read more about HERS and why it's important to you!
