PIER-sponsored research, development and demonstration (RD&D) has focused on development of integrated lighting systems for shared occupant spaces such as classrooms and conference rooms. These systems combine energy-efficient luminaires, multi-level scene control, occupancy sensors and daylight harvesting to create optimized lighting systems tailored for the modern learning space.
The State Partnership for Energy Efficient Demonstrations (SPEED) program drives the market adoption of energy efficient technologies. Managed through the California Institute for Energy and Environment (CIEE), SPEED has conducted more than 100 demonstrations and other technology-transfer projects across the state, showcasing the benefits of best practices and state-of-the-art solutions.
Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
Demonstrations on UC and CSU campuses have proven that SPEED technologies offer reliable, cost-effective solutions for achieving deep energy savings. Effective July 1, 2014, many SPEED technologies will be required under California’s 2013 Title 24 Building Energy Efficiency Standards.
The California Lighting Technology Center (CLTC) partnered with Finelite, Inc. and Adura Technologies to develop and demonstrate a unique, wireless task/ambient office lighting solution ideally suited for the retrofit market. The system consists of two key elements: a task/ambient lighting system and advanced, wireless lighting controls. The combination provides substantially reduced energy use, improved lighting quality, and personal lighting control for individual work spaces, without the need for any additional wiring or rewiring of existing luminaires or lighting circuits.
CLTC partnered with the California Army National Guard through the Public Interest Energy Research (PIER) Program to demonstrate an Interior Office Lighting System (IOLS) at the Joint Force Headquarters in Sacramento, CA. The project demonstrated the energy and maintenance savings that can be achieved by using a combination of low ambient lighting, high-quality task lighting and advanced lighting controls. Average IOLS energy savings is 40 – 50%.
The Department of Motor Vehicles (DMV) implemented the IOLS in a planned multiyear renovation of its 520,000-square-foot headquarters in Sacramento, CA. The original lighting goal was to provide more uniform task lighting and higher visual comfort. Original designs fell short of these goals. The IOLS, in contrast, met design objectives and increased energy savings.
Lighting California's Future – The Advanced LED Downlights project takes downlights in a whole new direction—up! The LCF project partners developed a dimmable downlighting system based on indirect optical design that reduces glare, decreases installation time, averages LED color variations and improves thermal management.
Lighting California's Future – Lighting controls systems are readily available in the market that turn lights off when spaces are unoccupied or when sufficient daylight is available. However, installing these systems involves new wiring or rewiring and can be an expensive proposition to retrofit existing buildings. Adura Technologies, in partnership with the California Lighting Technology Center, developed a wireless integrated photosensor and motion sensor system that communicates wirelessly through radio frequency to circumvent this issue.
The UC Davis Smart Lighting Initiative was established in 2010 to improve the quality and efficiency of both indoor and outdoor lighting on campus. The initiative's primary goal is to reduce UC Davis's electricity use for lighting by 60 percent, based on 2007 levels of energy use. The effort was inspired by the California Public Utilities Commission (CPUC) and its call to reduce statewide electricity consumption for lighting by 60 percent or more by 2020.
