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%.
 

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.

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%.

Adaptive Exterior Lighting, UC Santa Barbara

Post-top fixtures at Kirby Crossing in the University of California, Santa Barbara (UCSB).

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. 

LED Lamp Project Lights the Way to Flicker-Free Replacement

05/15/2014

Jade Sky Technologies (“JST”) collaborated with UC Davis's California Lighting Technology Center (CLTC) on a project designed to further the development of replacement lamps that meet the Voluntary California Quality LED Lamp Specification. Lab testing and characterization at CLTC showed that lamps incorporating JST's driver architecture met, or exceeded, the California Quality specification, using cost-effective and easily accessible components.

California Quality Standard and the LED Performance Database

05/14/2014

The Voluntary California Quality LED Lamp Specification requires that LED lamps meet certain product performance criteria. This “California Quality” specification was developed by the California Energy Commission in collaboration with the California Public Utilities Commission (CPUC) to accelerate consumer adoption of LED lamps. Many California utilities are using the California Quality Specification to determine which lamps they will include in their rebate and incentive programs.

Semico IMPACT Smart Lighting 2014: Brilliant Opportunities for Building Automation, Santa Clara
Presented by Konstantinos Papamichael

On April 23, 2014, CLTC Co-director Konstantinos Papamichael presented at Semico IMPACT Smart Lighting 2014: Brilliant Opportunities for Building Automation. He discussed lighting control strategies and emerging technologies that maximize the energy-efficiency and functionality of both electric lighting and daylighting systems.
