HERS (Home Energy Rating System) Rating is a standardized assessment of a home's energy efficiency. It quantifies the energy performance by comparing the home's energy use to a reference home built to code. A lower HERS score indicates better efficiency; a HERS score of 0 represents a net-zero energy home, while 100 signifies the energy use of a standard new home. It id used to guide energy improvements and certify home’s energy-saving features
-
