The California Energy Commission (CEC) updates the Energy Code every three years. On August 11, 2021, the CEC adopted the 2022 Energy Code. In December, it was approved by the California Building Standards Commission for inclusion into the California Building Standards Code. The 2022 Energy Code encourages efficient electric heat pumps, establishes electric-ready requirements for new homes, expands solar photovoltaic and battery storage standards, strengthens ventilation standards, and more. Buildings whose permit applications are applied for on or after January 1, 2023, must comply with the 2022 Energy Code.

Regulatory Advisory: Low-Rise Multifamily Compliance Forms for the 2022 Energy Code
The 2022 Building Energy Efficiency Standards (Energy Code), which goes into effect January 1, 2023, introduced new requirements for low-rise multifamily (LRMF) buildings and includes the registration of new LRMF compliance documentation.

The two companies certified as residential data registries are creating systems to process and register the new required LRMF compliance documents. Development is ongoing but will not be ready when the 2022 Energy Code goes into effect. As a result, for LRMF buildings only, there will be no approved data registry capable of registering compliance documentation for this building type until a later date.

The California Energy Commission staff recommends local authorities having jurisdiction (AHJs) take several steps to ensure that permitting for LRMF buildings under the 2022 Energy Code is not delayed. Read the full Regulatory Advisory issued November 18, 2022, published in the 2022 Energy Code Compliance Manuals and Forms docket (21-BSTD-04). Check back here or in the docket for possible updates or more information.

Reference Appendices
2022 Energy Code: Reference Appendices are adopted along with the Energy Code and contain data and other information that helps builders comply with the standards. The Reference Appendices includes sections on weather data, performance of assemblies with insulation, and residential and nonresidential tests and procedures.

Compliance Manuals
These documents, a part of the energy conservation manual, are designed to help the building industry comply with and regulators enforce the 2022 Energy Code for residential, nonresidential, and multifamily buildings. They are written as a reference and an instructional guide and can be helpful for anyone that is directly or indirectly involved in design and construction.

Compliance Documents - Forms

Compliance Software
CEC approved software to demonstrate performance compliance with residential and nonresidential provisions of the 2022 Energy Code. Performance modeling allows a user to assess building system performance or different building components against the Energy Code baseline.

Alternative Calculation Method (ACM) Manuals
These manuals identify the modeling rules used within the compliance software.

Data Registry Requirements Manual
This manual is intended to aid in designing and implementing software procedures and user interface features. As a resource for data registry providers, it includes information and explanations regarding the functional and technical aspects of the requirements given in Reference Joint Appendix JA7.


  • Solar Assessment Tools
    Builders must verify and document the shading conditions of a building’s installed solar photovoltaic (PV) system by using the CEC-approved solar assessment tool.
  • Climate Zone Tool
    This tool helps to show addresses and locations quickly and accurately in relation to the geographic metes and bounds that determine California’s climate regions. Search by climate zone or zip code.
  • Special Cases for Building Energy Efficiency Standards
    Information about calculation methods and measures that cannot be properly accounted for in the approved compliance approaches.
  • Manufacturer Certification for Building Equipment
    Manufacturers certify to the CEC that the building equipment, products, and devices listed meet the applicable Energy Code requirements.
