National Association of Home Builders of the United States v. District of Columbia — D.C. Cir. (argued September 8, 2026)
The District of Columbia Circuit considers whether the Energy Policy and Conservation Act, or EPCA, preempts Washington's Clean Buildings Act. The local law requires certain new or substantially renovated buildings to meet a net-zero-energy standard and generally bars on-site fossil-fuel combustion. The home builders and allied groups say the ban effectively sets covered gas appliances' energy use at zero. The District says it regulates fuel source, not appliance performance. The district court agreed with the District and granted it summary judgment.
