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.
Photosensor control systems have been available for more than two decades, but they have struggled to gain widespread use due to issues with reliability. To address these issues, CLTC partnered with WattStopper, Walmart, Sacramento Municipal Utility District, Southern California Edison, and San Diego Gas & Electric Company to develop a more reliable, more effective daylighting control system capable of sensing changes in daylight levels with increased accuracy and responding with more appropriate adjustments in electric light levels.
This document provides overviews of state-of-the-art commercial, residential, and exterior lighting strategies and technologies followed by detailed analysis that demonstrates the significant energy or electricity savings potential of several of these best-practice alternatives.
Lighting accounts for approximately 25 percent of California’s energy use, making energy-efficient lighting technologies a vital part of the state’s strategy for meeting its legislated climate goals. The Lighting Action Plan details the lighting portion of the California Energy Efficiency Strategic Plan, a comprehensive roadmap outlining solutions for reducing California’s energy consumption.
Changes to the lighting requirements under Title 24, Part 6 took effect July 1, 2014. This brief guide offers an overview of important requirements and major updates to these lighting codes and standards.
To address California’s critical need for targeted, practical technology improvements that reduce lighting energy use and advance building energy-efficiency, in 2009, the California Energy Commission initiated a comprehensive lighting research, development, demonstration and outreach program in partnership with the California Lighting Technology Center.
