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.
Cooper Lighting – The Bidwell Mansion Visitor Center in Chico, California, now enjoys variety of energy-efficient, aesthetic and cost-saving benefits thanks to the HALO LED 600 Series recessed downlight from Cooper Lighting, a division of Cooper Industries.
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.”
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.
Core sunlighting systems deliver sunlight deep into multi-story building cores, where daylight is not available through skylights or windows. An effective core sunlighting system offers physiological and psychological benefits to occupants while dramatically improving the quality and color rendering of lighting, reducing lighting electricity use up to 75%, and reducing electricity loads during peak demand periods.
Wall packs offer an effective means of illuminating building perimeters, bolstering security and aiding wayfinding, but many are limited in terms of their efficiency, with minimal or nonexistent cutoff. Moreover, because wall packs typically operate in areas with low occupancy rates, they often waste energy fully illuminating vacant spaces for hours at a time every night.
Photosensor control systems have been available for more than two decades, but they have struggled to gain widespread use due to issues with reliability. To address these issues, CLTC partnered with WattStopper, Walmart, Sacramento Municipal Utility District, Southern California Edison, and San Diego Gas & Electric Company to develop a more reliable, more effective daylighting control system capable of sensing changes in daylight levels with increased accuracy and responding with more appropriate adjustments in electric light levels.
Lighting accounts for approximately 25 percent of California’s energy use, making energy-efficient lighting technologies a vital part of the state’s strategy for meeting its legislated climate goals. The Lighting Action Plan details the lighting portion of the California Energy Efficiency Strategic Plan, a comprehensive roadmap outlining solutions for reducing California’s energy consumption.
To address California’s critical need for targeted, practical technology improvements that reduce lighting energy use and advance building energy-efficiency, in 2009, the California Energy Commission initiated a comprehensive lighting research, development, demonstration and outreach program in partnership with the California Lighting Technology Center.
