Outdoor ‘Smart’ Lighting System to Save Energy, Enhance Safety

UC Davis — The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country, a roughly $1 million network of “smart” lights that talk to each other and adapt to their environment. The $950,000 project is part of the university’s Smart Lighting Initiative, established in 2010 to reduce campus lighting electrical use by 30 million kilowatt hours -- or to 60 percent of 2007 levels -- by 2015.

UC Davis — UC Davis' "smart" outdoor lighting network incorporates state-of-the-art technologies developed through CLTC.

Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors.

The Integrated Classroom Lighting System (ICLS) delivers flexible, high-quality, energy-efficient lighting that is easy to use and maintain. ICLS system retrofits can either utilize existing fixture housings, only replacing lamps and ballasts, or the existing fixtures can be entirely replaced with a one-to-one retrofit. ICLS fixture controls, with features such as scene control, dimming, daylight harvesting, and occupancy sensing, automatically maximize energy savings while giving teachers optimal control of their classroom lighting. 

Energy savings can be achieved in corridors and other secondary spaces with an occupancy-based adaptive lighting system. The adaptive lighting system installed at the Latham Square office building is based on Lutron's Energi TriPak solution, a stand-alone platform for adaptive lighting that employs cost-effective wireless control devices and programmable dimming ballasts. 

UC Davis — Michael Siminovitch, director of the California Lighting Technology Center, has been named the first Arthur H. Rosenfeld Chair in Energy Efficiency at the University of California, Davis. The designation honors both Siminovitch, a professor of design whose work is revolutionizing lighting throughout California, and Rosenfeld, considered the “father of energy efficiency.”

Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
