In 2013 the SPEED team collaborated with UC San Francisco to demonstrate three lighting retrofits of fluorescent fixtures. Three control systems, each with different system architectures, were installed in three different UCSF corridors. All three systems utilize occupancy controls, but each one provides a different level of control, different programming capabilities, and energy and maintenance monitoring features. The demonstrations produced energy savings of 53–68%, based on occupancy rates of 12–16%.
Phase 2 of the UC Davis Smart Lighting Initiative will upgrade lighting in offices, labs, classrooms, corridors, and other spaces in selected buildings built in 1985 or later. Implementation of energy-efficient light sources, vacancy sensors and lighting control systems will reduce energy use by an estimated 5.5 million kilowatt-hours annually, saving the campus about $475,000, according to Scott Arntzen, senior project manager with Design and Construction Management.
Join UC Davis representatives, including staff from CLTC and WCEC, at this year's CHESC event hosted by UC Santa Barbara. Visit booth #203 to learn about lighting and HVAC innovations tested through the State Partnership for Energy Efficient Demonstrations (SPEED). Information on incentives and project financing options will also be available.
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.
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.
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.
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.
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.
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.
