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
  • Transparent review and adoption process
  • Formal public review and comment process

RESNET created and maintains

  • The HERS® Index to allow for easy comparison of energy performance of homes
  • The HERS H20® rating to compare indoor and outdoor water usage of homes
  • The RESNET Carbon Rating Index provides a more accurate metric to measure emissions
  • National training and certification and quality assurance standards for Home Energy Raters
  • Two American National Standards Institute (ANSI) Standards supporting energy and water efficiency in homes
  • Six Standard Development Committees

RESNET’s Mission

To make the energy use of all homes transparent, thereby driving residential sector energy use toward net zero.
