To be certified under the DOE Zero Energy Ready Homes (ZERH) program, a home must meet all requirements of the applicable version based on building type, the builder/developer/plant must be registered as a ZERH program partner, and the project must be approved by an approved third-party verifier. Click the version icons below to view the requirements documents for each version of the ZERH program. Please note that Version 2 for Multifamily is still under development. A complete list of current and planned Program Versions and Implementation Timelines is provided in the table below.
