University lights the way for hospital energy savings

University lights the way for hospital energy savings
09/11/2014

UC Davis News and Information—As ambulances at a Vacaville hospital speed off to their next patient, an ultrasmart, energy-efficient system is lighting the way. Installed in partnership with the University of California, Davis, the lighting system now illuminates the emergency vehicle routes, parking lots and outdoor walkways of the NorthBay VacaValley Hospital. The system is reducing outdoor lighting energy use at the 24-hour site by 66 percent, saving about 29,000 kilowatt-hours annually -- enough to offset the greenhouse gas emissions of 7.2 tons of waste.

Adaptive Exterior Lighting, UC Santa Barbara

In 2013, UC Santa Barbara partnered with the SPEED team to demonstrate network controlled LED lighting for streetlights and post-top fixtures. These exterior fixtures were purchased with dimming power supplies and equipped with radio frequency (RF) control modules. The post-top fixtures were also equipped with occupancy sensors. These lighting controls allowed all the units to be incorporated into an adaptive mesh network control system that optimized the fixtures’ energy efficiency and gave the campus unprecedented control of its lighting. 

Bi-level Induction Area Luminaires

03/21/2011

The combination of occupancy controls, a bi-level generator, and an induction source produces an energy-efficient luminaire with exceptionally long life, good color quality, and dynamic light level response based on actual usage. The bi-level controls contribute additional savings that are directly proportional to automotive and pedestrian traffic patterns. Bi-level luminaires reduce to 50% power on vacancy and increase to 100% power on occupancy.

LED Linear Retrofit Solutions and Advanced Lighting Control Systems for Small Commercial Retail Applications

Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.

Smart Lighting Initiative: Phase 2

Smart Lighting Phase 2 in 43 buildings

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.

Singapore to Launch Lighting Technology Center in Collaboration with UC Davis

CLTC Inspires Sister Center in Singapore

The University of California, Davis, is collaborating with the Singapore Green Building Council (SGBC) and Singapore’s Building and Construction Authority (BCA) to develop a lighting efficiency demonstration and training center in Singapore. Leaders from the three institutions signed a Memorandum of Understanding (MOU) on September 12 stating goals and strategies for fostering sustainable lighting solutions through the new center.

LD+A Research Matters: Eyes on the Road

08/01/2013

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.

Case Study: UC Davis Exterior Lighting Retrofit

06/01/2009

Most parking garages use high intensity discharge light sources that operate continuously regardless of lighting needs. These facilities typically do not employ energy-saving control strategies such as daylighting or time clock scheduling, and no considerations are made for lighting control based on occupancy. Garage lighting, designed to only a single static level, wastes energy and contributes to peak demand during the day and light pollution at night.
