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%.
A basic adaptive lighting system is composed of occupancy sensors, dimmable ballasts and sources, and a communication platform for the system components. By combining commercially-available components, multiple solutions may be implemented to deliver occupancy-based, adaptive corridor lighting. Three of these solutions were demonstrated and evaluated in corridor applications in a multi-use building at the University of California, Davis.
The California Energy Commission’s Public Interest Energy Research (PIER) Program funded the demonstration of bi-level fluorescent parking garage luminaires that combine mature fluorescent sources with occupancy-based dimming controls. The Philips Day-Brite Vaporlume fluorescent strip fixture, equipped with an optional occupancy sensor and step-dimming ballast, automatically reduces power consumption upon vacancy and increases to full power upon occupancy. Bi-level products may be combined with traditional photocontrols to maximize energy savings.
Philips Day-Brite and CLTC partnered on this SPEED-sponsored project to demonstrate a adaptive high intensity discharge (HID) wall pack from Philips Day-Brite’s established NiteBrites product line. The product provides dynamic light levels to surrounding areas based on occupancy using a single HID lamp and fixture-integrated occupancy sensor.
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.
