Term: HERS

HERS IndexHome Energy Rating System (HERS) a standard for measuring a home’s energy efficiency. Developed by the Residential Energy Services Network (RESNET). The HERS Index measures a home’s energy efficiency. It includes the energy consumption from heating, cooling, water heating, lights, and some appliances. It is a numeric scale where the lower the number, the more energy efficient the home. A score of 100 corresponds to a typical new built home. A score between 30 and 40 corresponds to a Passive House. And a score of 0 corresponds to a net-zero-energy home, a home that produces as much energy as it uses.
