CLTC – The California Lighting Technology Center (CLTC), a research, development, and demonstration facility at the University of California, Davis, has installed more than 100 demonstrations of energy-efficient lighting since the Center’s inception in 2004. The wide range of demonstrations has been installed at University of California, California State University, California Community College campuses, and state and federal buildings throughout California in an effort to prove energy-efficient technology and report the findings to the public through case studies.
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.
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.
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.
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.
Last June UC Davis replaced 101 static HPS and MH wall packs with adaptive LED wall packs by Philips, equipping them with outdoor motion sensors by WattStopper and networked controls from Lumewave. Along with streetlights and post-top luminaires, the wall packs were incorporated into the Adaptive Campus Control System at UC Davis, via an RF network that provides campus-wide lighting control.
Wall packs offer an effective means of illuminating building perimeters, bolstering security and aiding wayfinding, but many are limited in terms of their efficiency, with minimal or nonexistent cutoff. Moreover, because wall packs typically operate in areas with low occupancy rates, they often waste energy fully illuminating vacant spaces for hours at a time every night.
In 2012, UC Davis upgraded its exterior lighting as part of the university’s Smart Lighting Initiative. Wall packs on campus, like other exterior lighting fixtures, were retrofitted with dimmable LED sources, motion sensors, and wireless controls. This allowed the units to be incorporated into an adaptive campuswide lighting control system. The system offers an intelligent, networked approach to lighting and energy management, with improved lighting quality and optimal energy efficiency.
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.
