California’s current Title 24 requirements for building energy efficiency call for some high-efficacy lighting in a limited number of residential space types, such as kitchens and bathrooms. A future code requirement that all residential lighting be high efficacy has the potential to yield significant energy savings across the state, but implementation must first be proven practical and cost-effective.
These presentation slides cover best practices for residential lighting design. The material is designed to help builders meet, or exceed, California's 2008 Title 24 Building Energy Efficiency Standards. It includes background and policy, common lighting terms and technology updates, guidance in residential lighting design, a step-by-step overview of the Title 24 compliance process, and additional resources.
LD+A – California will soon embark on a new round of aggressive energy efficiency programs, including rebates and incentives aimed at encouraging the market uptake of new lighting technologies. The new incentive programs will address the deep efficiency goals set through California’s Strategic Energy Plan and the Huffman Bill.
CLTC communicates and collaborates with the Energy Division of the California Public Utilities Commission (CPUC) to provide objective information and expert analysis that may inform the Commission’s lighting-related energy policies, programs and mandates. CLTC supports the CPUC’s Energy Division in its lighting-related goals, initiatives and activities, including the Lighting Action Plan, a near-term implementation guide for achieving the goals stated in the Lighting Chapter of California’s Long-Term Energy Efficiency Strategic Plan.
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.
