Zero Energy Designed Home Certification

Document / January 25, 2019 / Zero Net Energy

NBI and the Residential Energy Services Network (RESNET) have teamed up to launch an exciting new certification program: Zero Energy Designed Homes (ZED Homes). Now in a pilot phase, the program is intended to certify homes in which the HERS rating process provides a high degree of confidence that the home will reach zero energy performance.


This program will also be simple and convenient for utility programs and is intended to dramatically increase the opportunity for utility program administrators to leverage the HERS environment as a way to provide incentives for high-performance homes in their service territories.

The certification requirements are simple. To qualify for ZED Home certification, projects must meet both of these requirements:

  1. Home Energy Rating System (HERS) Index is 0 or lower
  2. Predicted total energy use minus onsite power production is zero or lower

The ZED Homes program will provide confidence to homebuyers that they are buying a best-in-class energy performing home, distinction to builders to showcase their top-tier projects, and a ready-made opportunity for utilities and program implementers to catalyze the market for zero energy homes.

While currently being piloted, NBI and RESNET expect to expand this program to certify homes whose actual energy performance has been demonstrated to reach zero over time. NBI will update this page as the program evolves. For questions and comments about the program, or if you are interested in participating, please contact Alexi Miller at [email protected].
