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.

Performance Testing Report: Omni-directional LED Replacement Lamps

08/07/2014

A number of lighting manufacturers now produce LED replacement lamps for traditional 60W incandescent lamps, and stakeholders at the state and national levels face decisions regarding quality standards for this product category. To assist these stakeholders and assess the current state of this segment of the lighting market, CLTC performed photometric and electrical tests on samples of 26 commercially available A19 and A21 omnidirectional LED replacement products.

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. 

Networked Adaptive Exterior Lighting for the Health Care Sector

05/28/2014

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install an energy-efficient, ultra-smart outdoor LED lighting system. The award-winning project was so successful that the NorthBay Healthcare group is now considering expanding the VacaValley system and retrofitting the outdoor lighting at other sites. 

LED Lamp Project Lights the Way to Flicker-Free Replacement

05/15/2014

Jade Sky Technologies (“JST”) collaborated with UC Davis's California Lighting Technology Center (CLTC) on a project designed to further the development of replacement lamps that meet the Voluntary California Quality LED Lamp Specification. Lab testing and characterization at CLTC showed that lamps incorporating JST's driver architecture met, or exceeded, the California Quality specification, using cost-effective and easily accessible components.

California Quality Standard and the LED Performance Database

05/14/2014

The Voluntary California Quality LED Lamp Specification requires that LED lamps meet certain product performance criteria. This “California Quality” specification was developed by the California Energy Commission in collaboration with the California Public Utilities Commission (CPUC) to accelerate consumer adoption of LED lamps. Many California utilities are using the California Quality Specification to determine which lamps they will include in their rebate and incentive programs.
