CLTC at UC Davis is on a mission to get energy-efficient lighting into offices and homes.
Business Wire – Adaptive LED parking structure lighting is unveiled at the South Entry Parking Lot top deck at the University of California, Davis.
PIER-sponsored research, development and demonstration (RD&D) has focused on development of integrated lighting systems for shared occupant spaces such as classrooms and conference rooms. These systems combine energy-efficient luminaires, multi-level scene control, occupancy sensors and daylight harvesting to create optimized lighting systems tailored for the modern learning space.
PIER sponsored research, development, and demonstration (RD&D) has focused on the combination of occupancy-based lighting controls and dynamically turnable light sources to create intelligent, bi-level luminaires for parking area applications.
The State Partnership for Energy Efficient Demonstrations (SPEED) program drives the market adoption of energy efficient technologies. Managed through the California Institute for Energy and Environment (CIEE), SPEED has conducted more than 100 demonstrations and other technology-transfer projects across the state, showcasing the benefits of best practices and state-of-the-art solutions.
Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.
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.
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.
