The California Lighting Technology Center (CLTC) at the University of California Davis collaborated with the California Energy Commission to provide this educational video series in support of the 2016 Building Energy Efficiency Standards (Title 24). Sensors and controls can achieve significant energy savings by automatically adjusting lighting based on time of day, available task needs, daylight, occupancy, and electricity supply or cost.
The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for heating, ventilating and air conditioning (HVAC), electric lighting and dynamic fenestration systems. The integrated system is referred to as the Integrated Building Control Retrofit Package (IBCRP), as it is aimed for retrofit projects in existing commercial buildings.
CLTC collaborated with the Emerging Technologies group at the Pacific Gas & Electric Company to evaluate linear LED lamps in a variety of fixture applications as well as identify any interoperability issues.
Lighting projects that involve updating CFL lighting systems should consider all viable retrofit options. When retrofitting between CFL four-pin lamps and LED solutions, it is important to observe safety precautions and consider performance variables.
Widespread adoption of LED lighting for general illumination applications is poised to be the single, largest advancement in lighting efficiency during the 21st century. Due to its potential, a variety of market actors have introduced LED products and made associated performance claims that have set the technology up with somewhat unrealistic expectations regarding system efficacy and longevity. To compete in this market, LED manufacturers have focused on research to improve efficacy and reduce product costs, often at the expense of product quality and feature optimization.

The 2015 Lighting Technology Overview (LTO) provides overviews of commercial and residential lighting technologies and strategies with the potential to significantly reduce California’s lighting energy use. The guide includes information on expected energy savings, factors to consider when comparing products, sample products, and case studies for indoor and outdoor lighting and controls technologies. Products in the guide include:
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
CLTC, in partnership with Southern California Edison, completed a project portfolio from 2014-2018 to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The projects have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
