Outdoor "Smart" Lighting System to Save Energy, Enhance Safety


UC Davis – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country, a roughly $1 million network of “smart” lights that talk to each other and adapt to their environment. The $950,000 project is part of the university’s Smart Lighting Initiative, established in 2010 to reduce campus lighting electrical use by 30 million kilowatt hours -- or to 60 percent of 2007 levels -- by 2015.

UC Davis Wins Best-Practice Award for Lighting


CLTC ​– The University of California, Davis, will receive a best-practice award for its adaptive exterior lighting system at this year's California Higher Education Sustainability Conference (CHESC), June 23–27, 2013 at UC Santa Barbara. The smart lighting network consists of more than 1,500 dimmable LED luminaires, occupancy sensors, and a radio-frequency network control system. The project is saving UC Davis an estimated 1 million kilowatt hours and $100,000 annually.

CLTC affiliate American Honda Motor Co., Inc., celebrated completion of the Honda Smart Home US project with an open house event on March 25, 2014 at UC Davis West Village. The zero net energy (ZNE) home is a model for residential sustainability, demonstrating best-practice solutions. CLTC has partnered with Honda to develop a forward-thinking lighting design for the project.

DOE Releases Model Specification for Adaptive Roadway Lighting Control Systems

Published: Tue, 05/28/2013

The U.S. Department of Energy's Municipal Solid-State Street Lighting Consortium (MSSLC) has released its Model Specification for Adaptive Control and Remote Monitoring of LED Roadway Luminaires, Version 1.0. The specification was prepared by the MSSLC Adaptive Control and Remote Monitoring Committee. It is intended to help those cities and utilities adopting LED street lighting select control systems appropriate to their varied needs.

SPEED Program

State Partnership for Energy Efficient Demonstrations (SPEED) Program

The California Energy Commission sponsors the development and demonstration of energy-efficient, environmentally safe building technologies. It does this, in part, through the State Partnership for Energy Efficient Demonstrations (SPEED), a program that demonstrates innovative lighting and HVAC technologies. The SPEED program is managed by the California Institute for Energy and Environment (CIEE), which is a branch of the University of California. The California Lighting Technology Center (CLTC) is subcontracted by CIEE to develop and implement lighting technology demonstrations.

Ubiquitous Communication by Light

Ubiquitous Communication by Light

Ubiquitous Communication by Light (UC-Light) is an emerging technology that uses visible light to perform wireless machine-to-machine communication. The mechanism at work with UC-Light is similar to the infrared technology used in TV remote controls, but UC-Light uses visible white light from modulated light emitting diodes (LEDs). Visible light communication (VLC) is potentially cheaper than conventional wireless communications because VLC can use pre-existing LED luminaires for communication purposes.

Adaptive Envelope Systems for Retail & Agriculture

Adaptive Envelope Systems for Retail & Agriculture

CLTC collaborated with the California Energy Commission and the California Institute for Energy and Environment (CIEE) to develop adaptive envelope technologies for retail and agricultural buildings. The objective was to develop systems that optimize both lighting and thermal efficiency in these facilities, using advanced fenestration materials, daylighting technologies and lighting controls.

Networked LED Streetlights with Intelligent Controls

Networked LED Streetlights with Intelligent Controls

CLTC has collaborated with the City of Davis to field-test a network-controlled LED street lighting system along Second Street in Davis, CA. The project team will demonstrate and measure the effects of various sensor technologies and communication protocols for adaptive street lighting, in terms of performance characteristics and energy savings. The demonstration involved replacing 12 high-pressure sodium (HPS) fixtures with LED streetlights and retrofitting 14 existing LED fixtures with dimming capabilities and controls.

Adaptive Corridors

CLTC research, demonstrations and case studies have shown adaptive corridor and stairwell lighting systems are a cost-effective strategy for achieving lighting energy savings of 40–50%. This is because many stairwells and corridors are illuminated continuously, despite low occupancy rates, and are usually equipped with standard, non-dimmable ballasts and operated with wall switches or from a panel box.

Parking Today, "DC Complex Installs New Lighting in Garage to Reduce Crime Threat"


In early summer 2011, Capitol Park Plaza in Washington, DC, began the initial stages of a major lighting overhaul at its parking garage for apartment tenants. By working directly with research partners and testing facilities, such as CLTC at UC Davis, EverLast Lighting has been able to bring an innovative lighting solution to the market.
