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.
Adaptive exterior lighting products are entering the marketplace at a rapid rate. By coupling features such as occupancy-based lighting controls with efficacious, dimmable sources, these solutions offer 30 – 75% energy savings over traditional systems.
This business case describes four adaptive lighting systems. All four cut energy use and electricity costs by over 70%. Large-scale upgrades generally yield the best results, and they qualify for the biggest incentives.
In the summer of 2010 the California Lighting Technology Center (CLTC) and Philips Hadco produced an adaptive solution that combined a dimmable LED source and a mounting collar equipped with occupancy sensors. The collar provides 360-degree occupancy sensor coverage. This demonstration involved whole-head replacement of the existing luminaires, but results could also be achieved with a retrofit kit. The new luminaires feature good color quality, improved efficiency and a longer lifespan.
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.
