California Title 24 Compliance

California's Title 24 Building Energy Efficiency Standards are among the most stringent energy codes in the United States, with requirements that significantly exceed the national IECC baseline. AI compliance checking for Title 24 handles the state's unique prescriptive and performance approaches, including the mandatory measures, the prescriptive requirements, and the performance approach using CBECC software.

The Title 24 lighting requirements are particularly detailed, with separate power density limits for different space types, mandatory automatic controls requirements (occupancy sensors, daylight responsive controls, demand response capabilities), and outdoor lighting power limits. AI checks the lighting design against all applicable requirements simultaneously, including the control requirements that are often overlooked during design but caught during plan review.

California's reach codes — local amendments that exceed the state baseline — add another layer of complexity. Cities like San Francisco, Berkeley, and Santa Monica have adopted all-electric building requirements, enhanced envelope standards, and EV charging mandates that go beyond Title 24. AI maintains the local requirement sets for each jurisdiction and checks projects against the applicable combination of Title 24 plus local amendments.
