LD+A Research Matters: Performance Evaluation of a Solar Tracking Lighting System
06/07/2022
CLTC recently partnered with the California Energy Commission, Sonoma Clean Power Authority, and Frontier Energy Inc. to evaluate opportunities in emerging daylighting technologies. One such technology is a solar-tracking lighting system, which delivers daylight via optical fibers to core building areas that otherwise do not have access to daylight.
LD+A Research Matters: Integral Metering & Reporting Capabilities of Networked Lighting Controls
03/29/2022
Networked lighting control (NLC) systems have proven they can successfully reduce demand and save energy in real-world applications through a combination of basic and advanced control strategies. However, the potential of NLCs’ integral metering and reporting capabilities to provide cost effective energy-use data for incentive programs
and outcome-based code opportunities has not been fully realized. This is, in part, due to the variety of metering and reporting approaches used by today’s NLCs.
Adaptive Lighting in Outdoor Security Applications
11/16/2021
Today, adaptive lighting, which is lighting controlled by occupancy sensors or schedules that adjust light levels based on actual site conditions, is considered best practice for numerous outdoor applications. Adaptive lighting has been adopted as part of some commercial energy standards and the strategy is now included in many outdoor lighting specifications and design guides. Outdoor areas with heightened security requirements, however, are often excluded from adaptive lighting control requirements and these areas remain lit with high, uniform levels of static illumination.
LD+A Research Matters: A New R&D Center for Mexico's Lighting Industry
08/09/2021
In the fall of 2017, the Mexican Ministry of Energy awarded funding to the Universidad Autónoma de Guadalajara in collaboration with the University of California Davis to establish a lighting technology and design research center known as the Centro de Tecnología en Iluminación (CTI). This is a multi-year, public-private investment focused on addressing growing climate change concerns through translational research committed to clean energy and sustainability in Mexico.
LD+A Research Matters: Outcome-Based Codes Offer a New Path
05/18/2021
Outcome-based energy codes are relatively new. They incorporate strategies that quantify a building’s actual energy performance over time to demonstrate code compliance. The term "outcome-based" refers to the fact that compliance is linked with a building’s actual energy “outcome” which may be measured post-occupancy.
Daylight Harvesting for Commercial Buildings
04/13/2021
CLTC is excited to announce an update to the Daylight Harvesting for Commercial Buildings publication! This in-depth tool provides guidance towards meeting and exceeding California's 2019 Energy Code for daylight harvesting.
Daylight design guidance and associated Energy Code are provided in an easy to read, side-by-side layout, organized into sections for each building-related discipline that impacts daylight performance from building siting, through architectural and interior design, to construction, commissioning and operation.
Educational Video: 2019 High-Efficacy Lighting for Residential Applications
11/30/2020
The California Lighting Technology Center (CLTC) at the University of California Davis collaborated with Southern California Edison, RMS Energy Consulting, LLC and the California Energy Commission to provide this educational video in support of the 2019 Building Energy Efficiency Standards (Title 24). California’s new Building Energy Efficiency Standards took effect on January 1, 2020.
