DOE Zero Energy Ready Home

The DOE Zero Energy Ready Home (DOEZERH) program is the evolution of the previous DOE Challenge Home program. The DOEZERH program leverages the service providers and partners of the ENERGY STAR New Homes & Apartments program, adds additional requirements for certification through the Indoor airPLUS certification, and sets prerequisites for solar-ready on applicable homes.

This program requires high efficiency equipment, above-code envelope, and high performance thresholds. Earning the DOE Zero Energy Ready Home certification is also used to earn the 45L tax credit.
