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 is partnering with the UC Davis Energy Efficiency Center (EEC) to address untapped efficiency opportunities in the Multi-Tenant Light Commercial (MTLC) building sector. The project is focused on identifying and overcoming the biggest barriers to energy-efficiency retrofits in the MTLC market. More than half of the energy-saving contributions of the team's proposed solutions will come from lighting-related retrofits, as the group hopes to reduce interior lighting energy consumption by 20% and exterior lighting energy consumption by as much as 50%.
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.
The California legislature mandated a reduction in lighting energy use in the commercial and residential building sectors per Assembly Bill 1109, the California Lighting Efficiency and Toxics Reduction Act (AB 1109, Huffman, Chapter 534, Statutes of 2007). Per AB 1109, California must reduce its lighting energy use between 2007 and 2018 by 50% for residential interior lighting and by 25% for commercial interior and outdoor lighting.
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.
