The second most common Title 24 acceptance test is the NRCA-LTI-03-A acceptance test.  This is the test for compliance of automatic daylighting systems.  Daylighting is required in new construction with >120W in the primary daylight zones, and tenant improvements with >85% of the allowable W/sqft.  For compliance, a system that automatically reduces electric lighting when daylight is present must be installed and calibrated to the appropriate Title 24 Code requirements.
