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 collaboration with the Office of Naval Research, developed new, improved strategies and technologies for occupancy sensing in outdoor applications that address the shortcomings of existing strategies and technologies. The project approach included the systematic identification of the pros and cons of existing strategies and technologies, formulation of new strategies and/or technologies, and implementation of new approaches in the form of laboratory prototypes that will be tested and demonstrated in the laboratory and in the field.
The potential to reduce energy consumption in existing and commercial buildings is enormous. On average, 30% of the energy used in commercial buildings is wasted, according to the U.S. Environmental Protection Agency. Lighting has a large potential for energy savings for any U.S. building end use, with a significant fraction of that potential coming from lighting controls.
One of the features of networked lighting controls is the ability to monitor lighting energy use over time and adjust the system to achieve the best possible performance. Facility managers can match system use to expectations and adjust system settings to result in optimized user comfort while maximizing savings. Real-time energy monitoring offered by some control systems has also piqued the interest of utility program managers in locations in the U.S. where rebates assist with the accelerated adoption of emerging technologies.
CLTC, in partnership with Southern California Edison, completed a project portfolio from 2014-2018 to assess controls, lighting, and daylighting technologies and their potential for commercial applications. The projects 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.

CLTC, in partnership with the Center for Sustainable Energy (CSE) and the California IBEW-NECA Labor Management Cooperation Committee (CA LMCC) is working to expand career pathways in the electrical industry. With new funding from the California Energy Commission, CLTC will develop training resources to increase workforce development opportunities in disadvantaged communities.
