Under the Hood of California's Title 24 Lighting Requirements
Code Green News

The Title-24, Part 6 – 2013 Lighting Acceptance Test is required for projects with New Construction, Additions, or Alterations of a space involving >10% of total lighting fixtures or >40 ballasts or luminaires,

The Acceptance Testing process consists of Plan Review, Construction Inspection, and Functional Testing before the Certificate of Occupancy is issued to the space and typically takes a few hours to complete. A certified Lighting Acceptance Technician is required to complete the Lighting Acceptance Forms to ensure the new fixtures and controls are installed properly and meet all Title-24 requirements. The Lighting Acceptance Technician certifies documentation, verifies installation certification, and completes acceptance tests on indoor and outdoor lighting equipment and controls.

It is the last step to obtain the Certificate of Occupancy for a space. Failure to complete a lighting acceptance test may cause a delay in the ability to occupy the completed building space.

Design Engineer – Designs the space to T24 code and generates the Certificates of Compliance.

Lighting subcontractor – Installs lighting equipment and fills out Certificate of Installation.

General Contractor – Provides Certificates to Acceptance Technician for review, submits Certificates of Acceptance forms after AT to permitting agency.

There can be up to 4 parts to the Acceptance Test depending on the type of lighting present in a project, each involves an inspection and test component –

1. Indoor Lighting Controls for Occupancy Sensors and Automatic Time-Switches(NRCA-LTI-02-A)
Occupancy Sensors
• Inspect – Verify no false-ons, sensors located >4 ft away from HVAC diffusers, no obstructions, CEC Certified (Title 20), and no audible sound
• Test – occupied/unoccupied states, sensitivity, time delay, sampling allowed if greater than 7
Automatic Time Switches
• Inspect – Documentation, Programming (Date/Time, Building Schedule, Holiday/Weekend), Override 5 zones, not allowed for zones >5,000 sqft
3. Demand Response Lighting Controls (NRCA-LTI-04-A)
• Inspect – Required for buildings >10,000 sqft, automatic response to a utility request, reduce between 15-50% of lighting load
• Test – Output tests (full/minimum) using a preferred method (Illuminance/Current), Area-Weighted Calcs, Sampling allowed for greater than 7
4. Outdoor Lighting (NRCA-LTO-02-A)
• Inspect – Photocontrols/Astronomical Time-Switch required with motion sensors for Incandescent fixtures > 100W, height of fixture <24’, and <=1,500W/zone. Also reduce lighting levels of sales, facades, ornamental hardscapes, and outdoor dining fixtures. Inspect drawings, overlap, and obstructions of motion sensors. Inspect Circuits, Autonomic Time Clock, Programmable Schedules, and Lighting reduction capability of Part-Night Controls.
