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 objective of this project is to develop and commercialize LED-based lighting kits for ceiling and exhaust fans in residential applications. Additionally, the project explores the integration of control systems to the LED fan systems to determine if additional energy savings can be achieved in a cost-effective manner.
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.
PIER-sponsored research, development, and demonstration has focused on the combination of occupancy-based lighting controls and broad-spectrum light sources to create intelligent, bi-level luminaires designed for street and parking area applications. These products achieve 30 – 75% energy savings compared to traditional street and area luminaires, meet stringent energy-efficiency standards, and provide excellent light distribution for reduced night sky pollution.
The Integrated Classroom Lighting System (ICLS) delivers flexible, high-quality, energy-efficient lighting that is easy to use and maintain. ICLS system retrofits can either utilize existing fixture housings, only replacing lamps and ballasts, or the existing fixtures can be entirely replaced with a one-to-one retrofit. ICLS fixture controls, with features such as scene control, dimming, daylight harvesting, and occupancy sensing, automatically maximize energy savings while giving teachers optimal control of their classroom lighting.
Energy savings can be achieved in corridors and other secondary spaces with an occupancy-based adaptive lighting system. The adaptive lighting system installed at the Latham Square office building is based on Lutron's Energi TriPak solution, a stand-alone platform for adaptive lighting that employs cost-effective wireless control devices and programmable dimming ballasts.
Smart Planet – At the California Lighting Technology Center at UC Davis, Professor Michael Siminovitch discusses an array of LED and fluorescent lighting technologies including, down lighting systems for residential use, and exterior LED lighting for garages and parking lots.
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.
The New York Times – Parking garages are the third most frequent place for crime in the U.S. Security professionals agree that parking garage design influences the level of crime significantly. The easiest way to deter criminal activity in preexisting structures is by installing bright, white lights, coupled with occupancy sensor controls.
The Parking Professional – Michigan State University (MSU) has adopted a strong on-campus sustainability initiative. Adopting these standards for energy savings requires a challenging operating specification to follow, and MSU launched a major lighting overhaul in the parking garage at the Wharton Center last fall.
