The California Energy Commission’s Public Interest Energy Research (PIER) Program through the California Lighting Technology Center funded development of a bi-level parking garage luminaire that integrates state-of-the-art induction sources and occupancy-based dimming controls.
The PIER Program sponsored development of the adaptive LED bollard, an innovative technology designed to combat the energy wasted on overlighting unoccupied urban spaces. To successfully reduce energy consumption and provide dynamic light levels to the surrounding environment, project partners selected long-life light emitting diodes (LED) and fixture-integrated occupancy sensors to create a unique adaptive bollard. This combination delivers long life, low-energy consumption, and dynamic light output based on occupancy.
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.
Adura Technologies in partnership with the California Lighting Technology Center (CLTC) developed a wireless integrated photosensor and motion sensor (WIPAM) system that uses wireless communications to circumvent the complicated wiring issue, thus increasing the pool of buildings that could cost effectively benefit from lighting controls.
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.
California's Public Interest Energy Research (PIER) program sponsored the development of adaptive parking garage luminaires that integrate intelligent controls with adaptive electronic drivers or ballasts to control light output based on garage occupancy. CLTC partnered with PIER on three demonstrations of the technology in parking garages at CSU Sacramento, CSU Long Beach and the San Marcos Civic Center Parking Garage. Luminaires operate at a reduced power during vacancy and switch to full output when occupants approach the area.
Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors.
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.
