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%.

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. 

Adaptive Corridor Lighting, UC San Francisco

Adaptive Corridor Lighting Demonstration at UCSF
05/28/2014

In 2013 the SPEED team collaborated with UC San Francisco to demonstrate three lighting retrofits of fluorescent fixtures. Three control systems, each with different system architectures, were installed in three different UCSF corridors. All three systems utilize occupancy controls, but each one provides a different level of control, different programming capabilities, and energy and maintenance monitoring features. The demonstrations produced energy savings of 53–68%, based on occupancy rates of 12–16%.

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.

LED Linear Retrofit Solutions and Advanced Lighting Control Systems for Small Commercial Retail Applications

Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving 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. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.

Solar panels, special lighting could save Woodland schools big money

01/28/2014

KCRA— Woodland Joint Unified School District has installed solar canopies with energy-efficient adaptive lighting at 10 sites throughout the district. The project is expected to save the district thousands of dollars annually in electricity costs while drastically reducing carbon emissions and serving as an example for other school districts focused on improving sustainability and the cost-effectiveness of district operations.
