HERS scale

What is a RESNET HERS Index?

The RESNET HERS Index is a scoring system established by the Residential Energy Services Network (RESNET) in which a home built to the specifications of the RESNET HERS Reference Home (based on the 2006 International Energy Conservation Code) scores a RESNET HERS Index of approximately 100, while a net zero energy home scores a RESNET HERS Index of 0. The lower the RESNET HERS Index, the more efficient the home, which means you will save on your monthly energy bills.
