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.
PIER sponsored research, development, and demonstration (RD&D) has focused on the combination of occupancy-based lighting controls and dynamically turnable light sources to create intelligent, bi-level luminaires for parking area applications.
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.
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.
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 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.
Six private offices and 44 open cubicle spaces on the ninth floor of the University of California Office of the President Franklin Building in Oakland, CA, received an IOLS retrofit in 2009. This site was selected because it provided a large, open office space, a high-occupant density, and expected long-term employee occupancy in the space.
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.
