LD+A – CLTC and Berkeley Lab partnered to test the ADR-readiness of commercially available networked lighting control systems. All three systems tested were configured for automated demand response (ADR) communications, and all three successfully accessed the demand response automation server (DRAS) to retrieve DR events.
LD+A – CLTC researchers incorporated passive infrared (PIR) occupancy sensors and networked controls into a test set of dimmable LED roadway fixtures. The adaptive street lighting system yielded energy savings 27 to 42 percent greater than when the fixtures operated at a static level. All occupants, 100 percent, were detected by the PIR occupancy sensor selected for field testing, whether they were traveling on foot, by bicycle, on a motorcycle, or in an automobile.
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 – As retail stores make efforts to improve their sustainability and energy efficiency, a growing number are considering making the switch to directional LED replacement lamps. Compared to traditional halogen or incandescent sources, LED alternatives are about 75 percent more energy efficient, on average, and they last up to 25 times longer, but efficiency and long life are not enough.
The Parking Professional – Michigan State University (MSU) has adopted a strong on-campus sustainability initiative. Adopting these standards for energy savings requires a challenging operating specification to follow, and MSU launched a major lighting overhaul in the parking garage at the Wharton Center last fall.
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.
Lighting.com – The California Energy Commission recently updated its Title 24 Energy Efficiency Standards, improving what “up to code” means by 25 percent for residential buildings and 30 percent for commercial buildings. The new standards, now set to take effect July 1, 2014, introduce requirements for photosensors, occupancy sensors and multi-level lighting controls, both indoors and out, making adaptive lighting the new standard in California.
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.
NEMA ElectroIndustry Magazine— Professor Siminovitch’s push to “do more” is a common refrain heard around the halls at the CLTC — in fact, throughout the lighting industry and among energy efficiency regulators in California and beyond. It is perhaps why he has become one of the most influential voices in both lighting design and energy efficiency.
The Sacramento Bee – Representatives from more than 70 universities will gather at the UC Davis campus this week to discuss the latest practices in "greening" college campuses.
