About The Consortium - Background

• Created by the U.S. Department of Energy (DOE) in March 2010 using American Recovery and Reinvestment Act (ARRA) funding

• Supported by the DOE GATEWAY program

• Intended to be an educational resource on Solid-State street lighting and associated technology for those involved in lighting streets and other outdoor public areas.

As an independent resource, the Consortium is available to help those unfamiliar with LED technology identify important issues and how to how to begin the evaluation process

• …and to help accelerate adoption of SSL technology in the nations street lighting systems

MSSLC@Seattle.gov | www ssl.energy.gov/consortium.html

• Accelerate the adoption of high performance solid-state street and area lighting by leading end-user collaboration in the areas of performance, evaluation, application, and standardization.

Our Mission • Increase KNOWLEDGE around the performance, quality, and

application of SS Street Lighting. • Develop a national STRUCTURE to provide oversight and guidance

on the evaluation of SSL for public areas. • Influence national STANDARDIZATION of benchmarks,

classification, design, and performance criteria. Set standard benchmarks.

CLTC Mission & Activities

• To stimulate, facilitate & accelerate the development, application & commercialization of energy-efficient lighting and daylighting technologies.

• Mission-driven Activities – Research & Development – Field Testing & Demonstration – Outreach, Education & Training

• In partnership with utilities, manufacturers, end users, builders, designers, researchers, academicians, and governmental agencies

Huffman Bill (AB 1109) Signed 2007

Reduce average statewide lighting energy consumption by 2018 • Indoor Residential Lighting

not less than 50% from the 2007 levels

• Indoor Commercial Lighting

not less than 25% from the 2007 levels

• Outdoor Lighting

not less than 25% from the 2007 levels

Lighting Energy-Efficiency Strategy

Provide Right Light Right Source Where Right Luminaire & When Right Controls Needed Focus on retrofits

Adaptive Lighting Systems

Automatically adjust their light output… – Total Luminous Flux – Candle Power Distribution – Spectral Power Distribution

…based on sensor input from the space they serve – Occupancy / Vacancy – Daylight – DR Signals

…to optimize space and building performance – Comfort – Energy Savings – Peak Demand Reduction

All TAPS parking structures and lots were converted to bi-level induction (and some LED) saving 60–80%.

UC Davis LED Networked Outdoor Lighting

• 1500+ connected points of exterior lighting

• Direct monitoring and control of individual luminaires

• Automatic adaptation to environmental changes

– Daylight levels – Occupancy / vacancy – Direction of travel – Street surface reflectance – Fixture case temperature

• Multiple exterior applications – Street – Pathway – Post top – Wall packs

Technology Package: RF Control Network Profiles & interfaces Power to fixture on/off Bi-level with OFF 0-10V dimming control with 0V turning fixture power Off Dimming control in 5% increments
