Title 24 Compliant LED Light Fixtures
T24 2016 2019 JA8 High Efficacy LEDs By USAI Lighting
This standard is published by the California Energy Commission (CEC) and is widely regarded as the most strict energy code in the United States. It is updated once every three years and is made law in the state of California automatically; the most recent version is the 2019 Building Efficiency Standard which has been effective since January 1, 2020. No other states have officially elected this standard; however, some non-CA projects choose to meet Title 24 requirements for design purposes.
Similar to the ASHRAE standard, there is more than one way to meet Title 24 requirements. The code allows for three methods of calculation for compliance with the code when it comes to lighting energy use: the Complete Building method, the Area Category method, and the Tailored method.
Regardless of which calculation method you choose to use, extra power allowances are made for integration of daylight and controls. In addition, Title 24 now requires advanced dimming controls, occupancy and daylight sensors in nearly every application. Lastly, the standard requires a specific percentage of luminaires installed (varies by space type) to be classified as "high efficiency" luminaires. The JA8 appendix table is the standard’s current definition of what constitutes a High Efficacy LED. Listed below are links to the many USAI light fixture part numbers that are Title 24 compliant, separated by product family:
