Adaptive Exterior Lighting for the Health Care Sector

Post-retrofit lighting and controls at VacaValley Hospital, Vacaville, CA

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.

Smart Bi-level Parking Lighting Retrofit at University of California, Davis: Projected Energy Savings of More Than 50%


CLTC – California Lighting Technology Center (CLTC), UC Davis Energy Efficiency Center and development partners will host a ribbon cutting and reception for the new Smart Bi-level LED Lighting installed at UC Davis’ South Entry Parking Structure near the Robert and Margrit Mondavi Center for the Performing Arts. The LED light fixtures feature activity-sensing technology adapted and developed at CLTC.

CLTC completes more than 100 demonstrations of energy-efficient lighting


CLTC – The California Lighting Technology Center (CLTC), a research, development, and demonstration facility at the University of California, Davis, has installed more than 100 demonstrations of energy-efficient lighting since the Center’s inception in 2004. The wide range of demonstrations has been installed at University of California, California State University, California Community College campuses, and state and federal buildings throughout California in an effort to prove energy-efficient technology and report the findings to the public through case studies. 

UC Davis turns on smart lighting to save energy, be model for Californians


UC Davis – The University of California, Davis, turns on a new Smart Lighting Initiative to slash the amount of electricity it uses to illuminate its buildings and grounds. UC Davis is the first large institution in California to act on a September state mandate to reduce lighting energy use by 60 percent or more by 2020. 

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 Wins Best-Practice Award for Lighting


CLTC ​– The University of California, Davis, will receive a best-practice award for its adaptive exterior lighting system at this year's California Higher Education Sustainability Conference (CHESC), June 23–27, 2013 at UC Santa Barbara. The smart lighting network consists of more than 1,500 dimmable LED luminaires, occupancy sensors, and a radio-frequency network control system. The project is saving UC Davis an estimated 1 million kilowatt hours and $100,000 annually.

SPEED Program

State Partnership for Energy Efficient Demonstrations (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)

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

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.
