What AB 368 does, verified December 7, 2025
This bill requires the state energy resources commission to evaluate the cost-effectiveness of passive house energy efficiency standards by climate zone. The commission must use specific metrics such as long-term system cost to assess the standards. The bill also requires the commission to analyze the use of two passive house energy models and compare the cost-effectiveness of passive house construction to existing construction. The commission must submit a report to the legislature by July 1, 2028, documenting its findings and recommendations.

LEGISLATIVE COUNSEL'S DIGEST
AB 368, Ward. Energy: building standards: passive house standards.
Existing law requires the State Energy Resources Conservation and Development Commission to prescribe, by regulation, lighting, insulation, climate control system, and other building design and construction standards, and energy and water conservation design standards, for new residential and new nonresidential buildings to reduce the wasteful, uneconomic, inefficient, or unnecessary consumption of energy, as specified.
This bill would require the commission to evaluate the cost-effectiveness of passive house energy efficiency standards by California climate zone, using commission-adopted metrics such as long-term system cost. The bill would require the commission to evaluate the use of the 2 passive house energy models currently required for passive house certification in its analysis and the cost-effectiveness of passive house construction compared to existing construction, as specified. The bill would require the commission, on or before July 1, 2028, to submit a report to the Legislature documenting its findings and recommendations.
