HERS Index (Home Energy Rating System)

The HERS Index, short for Home Energy Rating System, is a scoring system that measures a home's energy efficiency. Ranging from 0 to 150, a lower score indicates better energy performance; a score of 100 represents a typical new home. Evaluators assess various factors, including insulation, heating, and cooling systems, to determine energy usage. A lower HERS score means lower energy bills and a reduced environmental impact. Home buyers and builders use this rating to make informed decisions about energy efficiency improvements and sustainable living.
