Commercial · Title 24 lighting controls

Commercial Lighting Controls, Designed around how the space works.

Coordinate occupancy sensors, daylight response, dimming and schedules with the lighting plan. Make the controls understandable for the people who use and maintain the building.

Project planning

A controls scope needs more than a device count. Bring the lighting plan and the intended operation of each room.

Start with Room use and control sequence
Equipment Fixtures, drivers and controls
Zones Occupancy and daylight
Completion Programming and functional checks
Testing Applicable acceptance scope

The starting point

Specify the behavior before choosing the switches.

A meeting room, open office and stockroom do not need the same lighting behavior. Define how lights turn on, respond to vacancy and daylight, and return to their scheduled state. Then match sensors, dimmers and drivers to that sequence.

A Title 24 lighting controls project also needs clear responsibilities for design, installation, programming and any required acceptance testing. Naming a control brand does not resolve those decisions or establish that an existing fixture will dim correctly.

Scope of work

From control intent to everyday operation.

1

Document existing controls

Identify control panels, sensors, switching zones and fixture drivers. Record systems that will remain and the areas affected by the alteration.

2

Define the sequence

Describe occupancy response, manual operation, scheduling and daylight behavior for each space. Resolve conflicting tenant and facility requirements early.

3

Check compatibility

Review the proposed control method against the fixture and driver documentation. Confirm interfaces before ordering mixed replacement equipment.

4

Install and identify

Coordinate sensor coverage, wall stations and control wiring with ceilings, partitions and furniture. Label zones so the operating intent remains traceable.

5

Program and check

Set the agreed sequence, check representative operating conditions and record the final settings. Resolve unexpected dimming or sensor behavior before handoff.

6

Coordinate acceptance

Identify required tests and documentation with the design team. Schedule a certified lighting-controls acceptance test technician where the project requires one.

Installation concept.

Project handoff

Leave a usable record of the settings.

Agree the handoff package with the facility team before programming begins.

Zone map

Connect switches, sensors and control channels to the spaces they serve.

Operating sequence

Record occupied, vacant, daylight and scheduled behavior in plain language.

Project documents

Retain applicable compliance, installation and acceptance records for the permitted scope.

User instructions

Explain everyday overrides and identify who can change protected programming settings.

Project scenarios

Choose the right starting point for the controls.

The practical question is what stays, what changes and how the parts will work together.

Existing fixtures

Controls-only changes

Verify the interface

New sensors or scheduling may be possible without replacing every fixture. Review the driver, wiring and available control interface before defining the retrofit.

Lighting upgrade

New LEDs and controls

Coordinate one package

Fixture selection and controls should be reviewed together. A lamp or driver change can affect dimming performance and the functions the new system can support.

New tenant layout

Reworked control zones

Follow the rooms

Partitions and room uses can change occupancy coverage and daylight zones. Update the sequence with the tenant layout rather than leaving the previous zoning in place.

Keep the compliance design, installation scope and acceptance-testing responsibilities explicit; no single product guarantees project compliance.

FAQ

Title 24 controls questions to settle early.

The California Energy Commission states that permit applications submitted on or after January 1, 2026 must comply with the 2025 Energy Code. Confirm the permit date and project requirements with the design team and enforcing agency. See the 2025 Energy Code page.

No. Review the specific alteration and applicable exceptions before assigning tests. When lighting-controls acceptance testing is required, the technician must hold the relevant certification. Installation and acceptance testing are separate responsibilities, even when coordinated within one project.

Often the existing fixtures can be evaluated for reuse, but compatibility must be checked. The driver, wiring, dimming method and required control behavior determine whether a controls-only change is practical.

A fixture, driver and control may not be compatible across the intended dimming range. Start with the installed model numbers and the manufacturers' documentation, then assess the actual circuit and programming rather than replacing devices by guesswork.

No. LED replacement changes the light source or fixture; controls determine when and how it operates. The scopes often overlap. Review LED retrofit options when the fixtures themselves need to change.

Ask for a zone map, a plain-language operating sequence, final settings and applicable test records. Identify access permissions and who maintains any software or control account. See the CEC's nonresidential compliance documents for the project forms.

Questions worth a closer look

From a short answer to a practical plan.

Explore the causes, tradeoffs and records behind these common project questions.

Should we replace every fixture when new LED lighting flickers?

Start by documenting the fixtures, drivers, controls and the conditions that trigger flicker. Review manufacturer compatibility and test an approved combination in a representative zone before committing to a full replacement; the circuit may also require investigation.

What should be ready before the lighting-controls acceptance technician arrives?

Confirm the applicable tests with the design team, install and configure the specified controls, and prepare zone information, approved documents and safe access. Assign correction and retesting responsibilities, and include the completed acceptance records in the facility handover.
