Title 24 · California Energy Code
Lighting controls, scheduling and acceptance testing
This hub summarizes the Part 6 rules for lighting control types, required schedules, and the acceptance‑testing and certification process (including CLCATT) needed for code compliance.
Last reviewed: July 6, 2026
Overview
This area of the California Energy Code covers the functional requirements, scheduling and verification of indoor and outdoor lighting controls — including daylighting, multilevel/continuous dimming, time-switch and motion-sensing controls — and the acceptance testing and installation certificates that demonstrate compliance. See key control provisions in §130.1 (daylighting and multilevel control requirements) and §130.2 (outdoor lighting scheduling and motion-sensing controls) for the control performance and scheduling rules .
Acceptance testing and certificate requirements (including test procedures in the Reference Nonresidential Appendices) are specified in §130.4 and related multifamily/outdoor provisions such as §160.5; when Part 1 certification applies, tests must be performed and documented before occupancy and by qualified technicians (see the Certified Lighting Controls Acceptance Test Technician, CLCATT, requirements) . Practical emphasis for designers and contractors: plan control sequences and schedules early, confirm required acceptance-test scopes (daylight, shut‑off, demand response, outdoor controls), and budget for the Certificate of Acceptance and any CLCATT fees .

Frequently asked questions
When is acceptance testing required for lighting controls?
Acceptance testing is required before an occupancy permit when controls are installed to comply with Part 6 requirements (examples listed in §130.4), and specific tests (daylight, shut‑off, demand response, outdoor controls) must follow the Reference Nonresidential Appendices NA7.6/NA7.8 .
Who may perform the required acceptance tests?
When certification under Part 1, §10‑103.1 is triggered, acceptance testing must be performed by a Certified Lighting Controls Acceptance Test Technician (CLCATT); the CLCATT must disclose a valid certification ID on the Certificate of Acceptance and follow the documentation requirements .
What must outdoor automatic scheduling controls do?
Automatic scheduling controls for outdoor lighting must be installed for all outdoor lighting and be capable of reducing lighting power 50–90% (and separately turning lighting OFF) during scheduled unoccupied periods, and allow at least two independent nighttime schedules with limited override capability .
