Widespread adoption of LED lighting for general illumination applications is poised to be the single, largest advancement in lighting efficiency during the 21st century. Due to its potential, a variety of market actors have introduced LED products and made associated performance claims that have set the technology up with somewhat unrealistic expectations regarding system efficacy and longevity. To compete in this market, LED manufacturers have focused on research to improve efficacy and reduce product costs, often at the expense of product quality and feature optimization.
CLTC, in partnership with Southern California Edison, recently kicked off a new project portfolio to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The new projects will have elements of market assessment, EM&V, and selected demonstrations.
The project focus is on evaluating the following technologies:
Advanced lighting control systems (ALCS) provide networked control and monitoring capabilities of connected luminaires via onboard metering and system reporting features. These advanced features allow system owners to dynamically balance visual comfort and lighting energy use. CLTC, in collaboration with SDG&E, developed a technology validation program to determine the accuracy and reliability of onboard metering and system reporting features of advanced lighting control systems.
The California Community Colleges (CCC) and the project team at the University of California collaborated on a shared initiative to improve and advance energy efficiency workforce development to meet industry standards and employer needs in the clean energy economy. The project team will assess and improve existing CCC training programs over the course of this project.
CLTC is partnering with Bosch to demonstrate the Bosch Direct Current Building-Scale Microgrid Platform (DCBMP) at an American Honda Motor Co., Inc. warehouse facility. Bosch will demonstrate the effectiveness of the DCBMP, a commercial-scale DC building microgrid that integrates advanced technologies to provide reliable power to the connected loads, resilience during grid outages, increased building energy efficiency and renewable energy utilization.
Each year, California schools spend approximately as much money on energy—$700 million—as they do on books and supplies.1 Education spending is a frequent point of debate among politicians and citizens, and maximizing the implementation of energy efficient technologies in school facilities could act as a way to increase education budgets without allocating additional public funds.
CLTC researchers are developing a standard methodology for conducting field demonstrations to better inform energy codes and standards enhancement.
The California Lighting Technology Center partnered with San Diego Gas & Electric and two Southern California cities on a project to help accelerate the adoption of energy-efficient advanced outdoor lighting control systems.
The project evaluated outdoor wireless lighting control systems that allows for remote operation and monitoring of fixtures using a web-enabled central management system. Laboratory and field assessments were conducted for separate systems installed as part of citywide retrofit projects in San Diego and Chula Vista.
