The CEC published the Existing Buildings Energy Efficiency Action Plan in 2015 to fulfill the requirements of Assembly Bill 758 (Skinner, Chapter 470, Statutes of 2009). The action plan was updated in 2016 and 2019. For 2021, the action plan was incorporated into the Integrated Energy Policy Report as a separate volume. The 2025 California Building Energy Action Plan (2025 Energy Action Plan) updates statewide strategies for existing building decarbonization. The 2025 Energy Action Plan presents a statewide, multiagency perspective on ways to achieve greater decarbonization of existing buildings through improved energy efficiency, electrification, and supporting strategies. The analysis that supports the recommendations is broken into 21 topics.
The 2025 Energy Action Plan fulfills the mandates in California Public Resources Code Sections 25310(c), 25403(c), and 25943(f) and incorporates the status report on CEC’s Equitable Building Decarbonization program, required by Senate Bill 306 (Caballero, Chapter 387, Statutes of 2023), as an appendix.
