Case Study

Integrated Office Lighting System at UC Davis

11/01/2011

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. 

Integrated Office Lighting System at the California Army National Guard

11/01/2011

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%. 

Adaptive Corridors at UC Davis

07/01/2011

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. 

Adaptive Fluorescent Parking Garage Luminaires at UC Santa Barbara

04/01/2011

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. 

Adaptive HID Wall Packs at CSU Chico

06/01/2010

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. 

Adaptive LED Bollards

08/01/2010

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.

Integrated Office Lighting System at the Department of Motor Vehicles in Sacramento, CA

05/01/2010

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. 

Integrated Office Lighting System at UC Office of the President

05/01/2010

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.

Wireless Integrated Photosensor and Motion Sensor at UC Santa Barbara

08/01/2010

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.
