Advanced Lighting Control Systems Bench Testing - Plug Load Controls

Advanced Lighting Control Systems (ALCS) Bench Testing – Plug Load Controls aims to revisit and refine the technology validation program developed in Phase I. ALCS Bench Testing - Plug Load Controls focuses on the plug load specific additions that are available with select ALCS and evaluates whether these advanced plug loads controllers (APLC) can accurately report the energy use of the connected plug loads consistent with utility requirements/needs.

LD+A Research Matters: Integral Metering & Reporting Capabilities of Networked Lighting Controls

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

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


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.

Daylight Harvesting for Commercial Buildings

Daylight Harvesting for Commercial Buildings for 2019 Building Energy Efficiency Standards

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


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.
