Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.
Best practices and lighting designs that meet, or exceed, California's 2013 Title 24 Building Energy Efficiency Standards.
California's 2008 and 2013 Title 24 standards require some high-efficacy lighting in a limited number of residential space types, such as kitchens and bathrooms. (Refer to the project page for more on code requirements for high-efficacy luminaire classification.) Future standards requiring all high-efficacy lighting in residential buildings could yield large-scale energy savings—if cost-effective technologies will satisfy consumers.
California’s 2013 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.
The retail sector constitutes one of the largest energy consumers in the U.S., and halogen parabolic aluminized reflector (PAR) and multifaceted reflector (MR) lamps are common retail lighting choices. LED replacement lamps have the potential to transform lighting energy use in this sector, and manufacturers of LED PAR and MR lamps now claim comparable photometric performance, as well as much greater longevity, than traditional halogen lamps.
PG&E—LED retail lighting showcase allows boutique owners to see, firsthand, how LED lamps perform in a realistic store setting.
CLTC partnered with the Pacific Gas and Electric Company (PG&E) and the California Energy Commission to assess how incentive programs and education efforts might best serve retailers' transition to LEDs.
Sinisa Novakovic, owner of Mishka’s café in downtown Davis, had two goals for the recent lighting upgrade in his café: create a cozy, inviting atmosphere for customers and save energy. In the main seating area alone he was able to cut his lighting energy use 85% by upgrading to LED lighting.
