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 Integrated Classroom Lighting System (ICLS) delivers flexible, high-quality, energy-efficient lighting that is easy to use and maintain. ICLS system retrofits can either utilize existing fixture housings, only replacing lamps and ballasts, or the existing fixtures can be entirely replaced with a one-to-one retrofit. ICLS fixture controls, with features such as scene control, dimming, daylight harvesting, and occupancy sensing, automatically maximize energy savings while giving teachers optimal control of their classroom lighting.
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.
Smart Planet – At the California Lighting Technology Center at UC Davis, Professor Michael Siminovitch 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.
EMerge Alliance – The EMerge Alliance is an open industry association leading the rapid adoption of safe, low-voltage direct-current (DC) power distribution and use in commercial building interiors announced it has added 15 more companies to its coalition. Now more than 60-members strong, the Alliance continues to gain the support of building industry and technology leaders in a collaborative effort to bring greater energy efficiency and sustainability to new and existing facilities.
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.
The New York Times – Parking garages are the third most frequent place for crime in the U.S. Security professionals agree that parking garage design influences the level of crime significantly. The easiest way to deter criminal activity in preexisting structures is by installing bright, white lights, coupled with occupancy sensor controls.
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.
