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.
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.
- 2022 Single-Family Residential Compliance Manual
- 2022 Nonresidential and Multifamily Compliance Manual
Compliance Documents
These forms are used to demonstrate compliance with mandatory requirements in residential and nonresidential buildings. Each bullet identifies how the specific set of forms is used.
- Residential Certificates of Compliance (CF1R, CF1R-ALT-05, CF1R-ALT-02)
Used to demonstrate the project design and equipment are compliant with the Energy Code at the time of permit application. - Residential Certificates of Installation (CF2R, CF2R-ALT-05, CF2R-ADD-02)
Used to demonstrate installations are compliant with the Energy Code at the time of construction and should be submitted by the installer to the inspector. - Residential Certificates of Verification (CF3R)
Used to demonstrate field verification and/or diagnostic testing is compliant with the Energy Code at the time of construction and should be submitted by the HERS rater to the inspector.
- Nonresidential Certificates of Compliance (NRCC)
Used to demonstrate the construction documents are compliant with the Energy Code at the time of permit application.
- Nonresidential Certificates of Installation (NRCI, NRCI-TEST)
Used to demonstrate installations are compliant with the Energy Code at the time of construction and should be submitted by the installer to the inspector - Nonresidential Certificates of Acceptance (NRCA)
Used to demonstrate compliance with acceptance testing requirements in the Energy Code. These documents must be completed by a field technician or Certified Acceptance Test Technician (ATT) and submitted to the inspector. - Nonresidential Certificates of Verification (NRCV)
Used to demonstrate compliance with Home Energy Rating System (HERS) verification requirements in the Energy Code. These documents must be completed by a HERS Rater and registered with a HERS Provider’s registry prior to submitting them to the inspector.
- Low-rise Multifamily Certificate of Compliance (LMCC)
Used to demonstrate the construction documents are compliant with the Energy Code at the time of permit application.
- Low-rise Multifamily Certificate of Installation (LMCI, LMCI-HERS)
Used to demonstrate installations are compliant with the Energy Code at the time of construction and should be submitted by the installer to the inspector. - Low-rise Multifamily Certificate of Verification (LMCV)
Used to demonstrate compliance with Home Energy Rating System (HERS) verification requirements in the Energy Code. These documents must be completed by a HERS Rater and registered with a HERS Provider’s registry prior to submitting them to the inspector.
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.
- 2022 Single-Family Residential ACM Reference Manual
- 2022 Nonresidential and Multifamily ACM Reference Manual
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.
Tools
- 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.
- Acceptance Test Technician Certification Provider Program - ATTCP
The program ensures that lighting control and mechanical contractors comply with the Energy Code in nonresidential buildings. - Home Energy Rating System Program - HERS
The program addresses construction defects and poor equipment installation, including HVAC systems and insulation, by evaluating homes.
