What Title 24 Lighting Commissioning Requires and Why It Matters
It's not a formality; it's a code requirement with real consequences for your certificate of occupancy.California’s Title 24 Building Energy Efficiency Standards set the requirements for energy use in new construction, and lighting commissioning is one of the final steps in demonstrating compliance.
It involves verifying that all lighting control systems — occupancy sensors, daylight controls, dimming systems, and time-based controls — are installed, programmed, and functioning in accordance with the approved energy compliance documents submitted during the permit process.
Failing commissioning — or skipping it — doesn’t just delay your certificate of occupancy. It can trigger a notice of correction requiring rework, retesting, and reinspection. Getting it right the first time is the only timeline that makes sense.
What Teams Need to Know About Title 24 Lighting Commissioning
Yes. While our preferred approach is to commission lighting systems that our own team installed — because it eliminates the coordination gap between installation and commissioning — we can provide certified Title 24 lighting commissioning services on projects where another electrical contractor performed the installation.
In those cases, our commissioning team reviews the installed systems against the approved energy compliance documents, performs the required functional testing, and handles the documentation and submission process. Contact our team to discuss the specifics of your project.
Title 24 commissioning covers all of the lighting control systems required under the energy compliance documents for the project, which typically include:
- Occupancy and vacancy sensors
- Daylight controls and photosensors
- Dimming systems and dimmable drivers
- Time-based controls and scheduling systems
- Automatic shut-off controls
- Multi-level lighting controls in applicable spaces
Every system is functionally tested, documented, and verified against the approved compliance documents before the acceptance forms are submitted to the enforcement agency.
A failed Title 24 commissioning inspection means the building cannot receive its certificate of occupancy until the deficiencies are corrected, retested, and re-documented. Depending on what failed and why, corrections could range from a simple programming adjustment to a more involved reinstallation of a control device.
The most common reason commissioning fails isn’t a product defect; it’s a gap between how the system was installed and how it was designed on the energy compliance documents. Bronco Electric prevents that gap by commissioning systems installed by our own electricians, with documentation maintained throughout the project.
