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.
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.
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 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.
In early summer 2011, Capitol Park Plaza in Washington, DC, began the initial stages of a major lighting overhaul at its parking garage for apartment tenants. By working directly with research partners and testing facilities, such as CLTC at UC Davis, EverLast Lighting has been able to bring an innovative lighting solution to the market.
This document provides overviews of exterior lighting technologies that would best be integrated into national parks as retrofits or new designs, as well as tips for evaluating light sources, performing a lighting audit, and pairing lamps with lighting controls. The key issues to consider when performing a retrofit or new lighting design are energy, cost, and maintenance savings, and this guide is intended to help make these decisions easier.
Due to the potential use of xenon lamps in outdoor applications, CLTC in collaboration with PG&E, developed an evaluation and testing program for xenon technology used in general illumination, outdoor applications. The research included under this project informed utilities about the performance and reliability of xenon lamps in these applications as compared to Light Emitting Diodes (LED), induction or other appropriate parking and area lighting solutions.
