About RESNET

What is The Residential Energy Services Network (RESNET)?

The Residential Energy Services Network or RESNET is a not-for-profit, membership corporation that is governed by a board of directors (who are elected by membership).

In April 1995, the National Association of State Energy Officials and Energy Rated Homes of America founded the Residential Energy Services Network (RESNET) to develop a national market for home energy rating systems and energy efficient mortgages.

RESNET is a recognized national standards-making body for building energy efficiency rating and certification systems in the United States involving:

  • A consensus based standard development and amendment process
