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.
Many of the emerging light sources used for exterior lighting, namely light-emitting diode (LED) and advanced ceramic metal halide (CMH) lamps, provide full-range dimming. Occupancy sensors have provided adaptive lighting controls in exterior parking and area lighting applications, but some applications are not compatible with sensor coverage patterns. In these scenarios, combining dimmable sources with a controller that dims based on time of day can achieve comparable energy savings to utilizing occupancy sensors.
The UC Davis Smart Lighting Initiative was established in 2010 to improve the quality and efficiency of both indoor and outdoor lighting on campus. The initiative's primary goal is to reduce UC Davis's electricity use for lighting by 60 percent, based on 2007 levels of energy use. The effort was inspired by the California Public Utilities Commission (CPUC) and its call to reduce statewide electricity consumption for lighting by 60 percent or more by 2020.
LD+A – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country this past June. Dubbed the Adaptive Campus Control System, it integrates over 1,600 individually addressed, dimmable LED luminaires with various applications – streetlights, wall packs, area lights, and post tops – into an advanced, wireless lighting controls network.
High Performing Buildings – The drive for building efficiency is creating innovative technologies that are finding their way into marketplace. This new feature in HPB magazine showcases the applications and capabilities of technologies in real projects, and also recognizes the providers of some of the innovative products.
UCTV – Presentations from winners of the Energy Efficiency Partnership Best Practice awards competition for projects that demonstrate successful Lighting Design/Retrofit and Monitoring Based Commissioning (MBCx) projects. Cal Poly San Luis Obispo, UC Davis, and San Diego CC present on projects that implemented emerging technology solutions to lighting applications in areas such as stairwells, parking lots, classrooms, and gymnasiums. CSU San Bernardino and UC Berkeley present MBCx projects that were implemented on their campuses.
Smart Planet – What types of smart lights will power our homes and offices in the next five to ten years? At the California Lighting Institute at UC Davis, Professor Michael Siminovitch shows us a giant integrated sphere that acts as an advanced light meter. He also discusses an array of LED and fluorescent lighting technologies including, down lighting systems for residential use, and exterior LED lighting for garages and parking lots.
On Wednesday, June 12, CLTC Director Michael Siminovitch received EverLast Lighting's first Energy Innovation Award for CLTC’s research and development of adaptive lighting controls. The award also recognized CLTC’s use of induction lighting in energy efficiency projects and the center’s commitment to reducing energy use for lighting on University of California campuses. CLTC has helped reduce exterior lighting energy consumption by over 60 percent at UC Davis alone through the university’s Smart Lighting Initiative.
CLTC and the Energy Efficiency Center at UC Davis partnered with Chevron Energy Solutions to map out California's current streetlight infrastructure. Researchers gathered data on 1.1 million streetlights from 212 cities throughout the state.
