Lighting Design and Title 24 Compliance for a 911 Emergency Call Center, California
We designed a new lighting system for a 911 emergency call center upgrade that came in 25% below the Title 24 allowed lighting power, with full controls compliance.

The challenge
The upgrade covered dispatch workstations and reception, a training room, supervisor and senior staff offices, two conference rooms and storage. Each space type carries its own lighting power allowance under the Area Category Method, and every space needs the mandatory controls.
What we delivered
- Laid out a new LED lighting system of 27 fixtures (2×4 and 2×2) across nine spaces.
- Calculated the allowed lighting power space by space using the Area Category Method: 2,090.5 W in total.
- Specified area controls, multi-level dimming and occupancy sensors in every space, and documented them on the LTI form.
The result
Designed lighting power is 1,560 W against 2,090.5 W allowed, 25% below the limit. Lighting power and controls both show as compliant on the NRCC-LTI form.
