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.
