Public Resources Code Section 25402 was enacted in 1975 as part of the enabling legislation establishing the California Energy Commission (CEC) and its mandates. This section requires the CEC to adopt, implement, and periodically update the Building Energy Efficiency Standards (Energy Code) for residential and nonresidential buildings. Accordingly, the CEC has adopted and periodically updated the Energy Code to ensure that building construction, system design, and installation meet energy efficiency and other state climate action goals. The CEC adopted the 2025 Energy Code on September 11, 2024. The California Building Standards Commission approved the 2025 Energy Code on December 17, 2024. Statewide enforcement of the 2025 Energy Code begins January 1, 2026.
Public Resources Code Section 25402.1(e) requires the CEC to certify an energy conservation manual no later than 180 days after the California Building Standards Commission approves the Energy Code to help designers, builders, and contractors of residential and nonresidential buildings comply with the updated Energy Code during design, construction or installation, and field verification. The energy conservation manual is not an adopted regulation but instead is certified by the CEC to provide guidance to the building industry.
The Data Registry Requirements Manual is one portion of the energy conservation manual, and the intent is to give a data registration provider a clear detailed description of how to comply with the Energy Code and Reference Joint Appendix 7. This Data Registry Requirements Manual provides additional detailed information and explanations regarding the functional and technical aspects of the requirements given in Reference Joint Appendix 7. This manual is intended as a resource for data registry providers to aid in the design and implementation of software procedures and user interface features for their data registries.
