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 – 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.
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.
CLTC research, demonstrations and case studies have shown adaptive corridor and stairwell lighting systems are a cost-effective strategy for achieving lighting energy savings of 40–50%. This is because many stairwells and corridors are illuminated continuously, despite low occupancy rates, and are usually equipped with standard, non-dimmable ballasts and operated with wall switches or from a panel box.
The primary objective of this study is to quantify the energy use in private offices that are equipped with bi-level switching and occupant controls. The baseline comparison is made to a theoretical case where the occupant has no control over their lighting and it is switched on and off solely by an occupancy sensor. In addition, this study looks closely at the possibilities for combining automatic and manual control to achieve the greatest energy savings and user satisfaction.
The objective of the Smart Corridor project is to quantify the potential energy savings in corridor lighting by implementing bi-level lighting technologies in commercial spaces such as office, hospitality, and educational buildings while also evaluating the market potential for the bi-level lighting strategy. The energy savings data gathered from this project is crucial to the large-scale implementation of bi-level strategies, as it will support the inclusion of bi-level lighting practices for secondary spaces in utility incentive programs and, eventually, building code language.
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.
