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 Outdoor Lighting for the Health Care Sector

07/14/2014

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install a network-controlled adaptive outdoor LED lighting system. The hospital already had up-to-date, energy-efficient outdoor lighting installed, yet this award-winning installation reduced the hospital's outdoor lighting energy use 66.4%. Energy savings correspond to occupancy rates of 35–55% observed at different areas of the site.

 

SPEED Business Case: Adaptive Street and Area Lighting

06/13/2014

This business case explores various lighting control options for LED retrofits of street and area lighting, along with funding and financing sources. It provides a general economic analysis of the costs and benefits associated with street/area retrofits and new-construction installations of post-top luminaires. The scenarios presented in this business case analysis have the potential to reduce lighting energy use and carbon emissions 72–93%, in areas with an average occupancy rate of 20%.
 

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. 

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.

UC Davis Institutional-Level Adaptive Controls for Exterior Lighting

02/24/2014

The Institutional-level Adaptive Controls for Exterior Lighting system incorporates exterior light points — pathways, building perimeters, parking lots, and roadways — into one smart, wireless system.

Originally launched as a pilot study, this system has since been installed for over 1,600 luminaires at the University of California, Davis.
