Lighting Retrofit: hospital secures 66% energy savings

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.

Prior to installing the networked LED system, NorthBay VacaValley Hospital’s  exterior lighting consisted of 40 induction luminaires, 13 high-pressure sodium  (HPS) luminaires, and 7 metal halide luminaires, all operating at full lighting power  throughout the night.

A total of 57 luminaires were installed with dimmable LED technology for the  lighting demonstration. Motion sensors were installed to provide maximum  coverage of the site, ensuring lights operate at sufficient levels when occupants  are detected and use less energy when areas are vacant. An “ultra-smart” lighting  control network was also put in place, giving facility managers the ability to adjust  lighting schedules, light levels and time-out settings, monitor the system’s  energy use, and receive automated alerts when luminaires require maintenance.

UC Davis’s California Lighting Technology Center (CLTC) customized the lighting  components to integrate them into a single, fully functional system and worked  with hospital personnel to ensure system settings meet the site’s lighting needs.  The retrofit reduced the site’s exterior lighting energy use by 66.4%, dramatically reduced lighting maintenance needs, and received positive reviews from about 88% of end-users surveyed for feedback.
