Home Energy Rating System (HERS)

Definition

Construction

  • A scoring system established by the Residential Energy Services network (RESNET) in which a home built to the specifications of the HERS Reference Home (based on the 2006 International Energy conservation Code) scores a HERS Index of 100, while a net zero energy home scores a HERS Index of 0. The lower a home's HERS Index, the more energy-efficient it is.
