Hospital Uses Networked Adaptive Outdoor Lighting System for Energy Savings

University of California, Davis teams up with VacaValley Hospital for ultrasmart lighting system

The Reporter, September 13, 2014

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.

The project is the first comprehensive study of “networked adaptive” outdoor lighting for the health care sector and could lead the way to more efficient lighting at other hospitals. Adaptive lighting uses tools such as occupancy sensors to adjust lighting to suit activity levels.
