The CLTC is excited to announce a new publication in our Lighting Best Practices series, the Daylight Harvesting for Commercial Buildings Guide! This publication provides guidance towards meeting and exceeding California's Building Energy Efficiency Standards for daylight harvesting.
So cool, so green! That’s what Sierra magazine says about the University of California, Davis — ranked No. 2 in the magazine’s 2015 “Cool Schools” report, released on Aug. 11.
This makes four out of the past five years that UC Davis has been among the top five in the environmental magazine’s evaluation of sustainability efforts at U.S. colleges and universities. UC Davis was the No. 1 “Cool School” in 2012.
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.
The Institutional-level Adaptive Controls for Exterior Lighting system incorporates exterior light points — pathways, building perimeters, parking lots, and roadways — into one smart, wireless system.
Originally launched as a pilot study, this system has since been installed for over 1,600 luminaires at the University of California, Davis.
Smart Lighting Phase 2 is coming to 43 buildings — and everyone in the campus community, even if you don’t work in one of them, is invited to town halls next week to learn more about the retrofit work.
Phase 2 of the UC Davis Smart Lighting Initiative will upgrade lighting in offices, labs, classrooms, corridors, and other spaces in selected buildings built in 1985 or later. Implementation of energy-efficient light sources, vacancy sensors and lighting control systems will reduce energy use by an estimated 5.5 million kilowatt-hours annually, saving the campus about $475,000, according to Scott Arntzen, senior project manager with Design and Construction Management.
Presentations from the Smart Schools Symposium 2013.
Many thanks to the attendees and exhibitors at the 2013 Smart Schools Symposium. CLTC and the team at Greenwise Joint Venture will be in touch in the days and weeks to come, sharing highlights from presentations, contact information for follow-up meetings and more tools and strategies for moving efficiency upgrades forward!
Most parking garages use high intensity discharge light sources that operate continuously regardless of lighting needs. These facilities typically do not employ energy-saving control strategies such as daylighting or time clock scheduling, and no considerations are made for lighting control based on occupancy. Garage lighting, designed to only a single static level, wastes energy and contributes to peak demand during the day and light pollution at night.
