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.

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 Retrofit Options for Linear Fluorescent Luminaires

Fluorescent lamps currently constitute 80 percent of lamps installed in the U.S. commercial sector, according to the Department of Energy's latest Lighting Market Characterization report. LED lighting products are receiving a great deal of 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.

Strategies for Successful Deployment of LED Streetlight Upgrades

11/20/2013

Public works staff, transportation directors and engineers, and municipal sustainability leaders are encouraged to attend this in-depth workshop on strategies for successful LED retrofit projects. Over 50 representatives from local agencies, including the City of Oakland, Foster City, San Bruno, and San Jose, will share their insights and experiences. Topics covered will include financing options, ways to engage stakeholders, and factors to consider when purchasing products. A roundtable discussion of best practices for timely action will also be on the agenda.

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.

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.
