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

NorthBay VacaValley Hospital networked adaptive exterior lighting post-retrofit
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.

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 Initiative: Phase 2

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.
