Relighting California Parking Lots

Publication Date: 

Under California's latest Title 24, Part 6 standards, new installations of exterior lighting must be controlled by motion sensors. Adding the same adaptive features to the lighting already installed in parking lots throughout California could also achieve sizable energy and cost savings in a very short period of time.

In the years leading up to the newest standards' adoption, CLTC partnered with California's State Partnership for Energy Efficient Demonstrations (SPEED) program on numerous demonstrations of energy-efficient light sources paired with adaptive lighting controls. This highly cost-effective solution has consistently produced energy savings of 40 – 70%, depending on occupancy rates and other variables. This one-page summary includes a list of SPEED demonstrations of adaptive parking luminaires installed since 2007, including links to case studies.
