UC Davis – The University of California, Davis, turns on a new Smart Lighting Initiative to slash the amount of electricity it uses to illuminate its buildings and grounds. UC Davis is the first large institution in California to act on a September state mandate to reduce lighting energy use by 60 percent or more by 2020.
CLTC – California cities could save more than $675 million over the next 15 years through streetlight upgrades, based on research conducted by the California Lighting Technology Center (CLTC) at UC Davis. Sponsored by Chevron Energy Solutions, the new research findings on the state of street lighting in California will be presented in a free webinar, "Lighting the Way to Safety, Savings and Innovation," 10:00 a.m., Wednesday, Feb. 29.
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.
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.
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.
This document provides overviews of exterior lighting technologies that would best be integrated into national parks as retrofits or new designs, as well as tips for evaluating light sources, performing a lighting audit, and pairing lamps with lighting controls. The key issues to consider when performing a retrofit or new lighting design are energy, cost, and maintenance savings, and this guide is intended to help make these decisions easier.
This study focuses on controls systems designed for street and parking lot lighting applications. These systems provide tools to manage and monitor city-wide streetlight assets remotely, including the potential to meter actual street lighting energy use. Networked controls that offer dimming capability can also provide energy savings through adaptive street lighting management, the practice of reducing lighting power and output as conditions change over time.
Representatives from 212 cities participated in the survey, reporting data on over 1 million municipal street lights. Results of the survey were analyzed and compiled in “The State of Street Lighting in California, 2012.”
