DOE Withdraws Zero-Emissions Building Definition
The voluntary guidance signals a shift in federal energy priorities but does not affect building codes or ongoing efficiency projects. December 29, 2025
By Jeff Wardon, Jr., Assistant Editor
The U.S. Department of Energy (DOE) recently withdrew its support for its National Definition of a Zero Emissions Building, which was issued in June 2024. This definition was voluntary and non-binding, intended as guidance rather than a regulatory requirement.
“The goals that underlie the National Definition of a Zero Emissions Building are not consistent with current administration priorities, and, as a result, DOE no longer supports the definition,” the DOE says in its notice. “In addition, DOE discourages states, municipalities, and standards-setting organizations from using and referencing the definition. The definition is no longer on the DOE website and DOE will not provide any technical assistance related to the definition.”
This move reflects a larger shift in federal energy policy, and not a reversal of existing building codes or mandates. The DOE frames net-zero guidance as conflicting with goals around domestic energy production, cost control and grid reliability. As a result, the withdrawal signals reduced federal leadership around a uniform national benchmark for zero-emissions buildings, a change that is more symbolic and directional than operational.
There is no impact on current building codes, standards or certification programs. Ongoing projects tied to efficiency, emissions reduction or electrification do not need to stop or reverse. State and local performance standards, utility programs and private-sector frameworks remain intact.
Ultimately, the decision marks a change in tone, not a complete stop for building decarbonization. Facility managers may face less federal clarity and more reliance on local codes and owner priorities. However, strategic energy decisions will continue to be driven by cost, risk and performance regardless of shifting federal definitions.
