Dynamic Exterior Lighting for Energy and Cost Savings in Department of Defense Installations
Exterior lighting for streets, roadways, parking lots, and other outside sites represents nearly 10% of the electricity consumed on military bases. Lighting in these areas typically consists of high pressure sodium or sometimes metal halide lamps that are normally controlled by photo-sensors located centrally or sometimes on each fixture. This limited functionality includes turning the lights on in the evening and off in the morning regardless of occupancy levels, thereby consuming more electricity than necessary.
Streetlighting Market Assessment & Survey
CLTC and the Energy Efficiency Center at UC Davis partnered with Chevron Energy Solutions to map out California's current streetlight infrastructure. Researchers gathered data on 1.1 million streetlights from 212 cities throughout the state.
Adaptive Exterior Lighting for the Health Care Sector
The California Lighting Technology Center (CLTC), Lawrence Berkeley National Laboratory (LBNL), and the U.S. Department of Energy recently completed a state-of-the-art lighting system demonstration at NorthBay VacaValley Hospital in Vacaville, California. On March 19th, 2014, the project received an award for “Best Use of Lighting Controls in a Single Facility” from the Lighting Energy Efficiency in Parking (LEEP) Campaign.
SPEED Program
The California Energy Commission sponsors the development and demonstration of energy-efficient, environmentally safe building technologies. It does this, in part, through the State Partnership for Energy Efficient Demonstrations (SPEED), a program that demonstrates innovative lighting and HVAC technologies. The SPEED program is managed by the California Institute for Energy and Environment (CIEE), which is a branch of the University of California. The California Lighting Technology Center (CLTC) is subcontracted by CIEE to develop and implement lighting technology demonstrations.
Western Exterior Occupancy Survey (WEOS)
CLTC partnered with Bonneville Power Administration, Pacific Gas and Electric Company and Southern California Edison to survey occupancy at four test sites in California and four test sites in Washington State. The sites selected for the research study represent market sectors identified as having the greatest potential to achieve energy savings with exterior adaptive lighting solutions.
Networked LED Streetlights with Intelligent Controls
CLTC has collaborated with the City of Davis to field-test a network-controlled LED street lighting system along Second Street in Davis, CA. The project team will demonstrate and measure the effects of various sensor technologies and communication protocols for adaptive street lighting, in terms of performance characteristics and energy savings. The demonstration involved replacing 12 high-pressure sodium (HPS) fixtures with LED streetlights and retrofitting 14 existing LED fixtures with dimming capabilities and controls.
Ultra-Smart Exterior Luminaires
“Smart” luminaires use integrated sensors to adapt light levels based on available daylight and/or occupancy patterns; “ultra-smart” luminaires function similarly, but they are also capable of communicating with one another through wireless radio frequency (RF) connections. This RF networking allows the luminaires to operate as a larger system. Different luminaire types can be incorporated into the network, including wall packs, post-tops, parking lot luminaires, and streetlights.
