Lighting Control Verification

Why Lighting Control Verification Is the Most Scrutinized Part of Title 24

If there is one area of Title 24 lighting inspections that consistently causes failures, it is lighting control verification. Fixtures may be efficient, layouts may look correct—but if controls don’t perform exactly as required, the project fails.

Lighting controls are the backbone of California’s energy strategy, which is why inspectors scrutinize them more closely than any other component.

Why Controls Matter More Than Fixtures
Title 24 assumes efficient fixtures are standard. The real energy savings come from how lighting is controlled, not just what is installed.

Controls regulate:
* When lights turn on and off
* How much light is delivered
* How systems respond to occupancy and daylight

Because of this, inspectors focus heavily on control performance during acceptance testing.

Common Control Issues Inspectors Flag
The most frequent control-related failures include:
* Occupancy sensors that don’t time out correctly
* Manual switches overriding automatic shutoff
* Daylight dimming not responding smoothly
* Incorrect zoning or grouping
* Control programming left in default mode
Even small programming errors can trigger re-inspection.

Contractor Best Practices
Contractors can reduce failures by:
* Testing all control scenarios before inspection
* Verifying that manual controls don’t defeat automation
* Coordinating early with the ATT
* Documenting all control configurations

Lighting controls are where Title 24 compliance is won or lost. Contractors who understand this pass inspections faster and with fewer surprises.
