Nonresidential Standards – Indoor Lighting Controls (section 130.1)
California Title 24 building energy code version 2025 is going to go into effect starting on January 1, 2026. Every three years, the State of California through the California Energy Commission releases its Building Energy Code updates. The 2025 standards will continue to improve upon the 2022 standards for new constructions, additions, & alterations to residential, non-residential, high rise residential, and hotel/motel buildings.
Before it’s official start, project planners, designers, and construction installers have already begun in preparation prior to January 2026. Let us dive into more details of the 2025 CA Energy Code changes.
