Research led by Skumatz Economic Research Associates Inc. and published by the DesignLights Consortium (DLC), Med-ford, Mass., shows the nonenergy benefits (NEBs) of networked lighting controls and a methodology for quantifying them. Designed for communication, networked lighting controls (NLCs) receive input from sensors, which is conveyed to lighting controllers that in turn send commands to the power controls. Because NLCs often interface with other building systems, they can perform other duties, such as monitoring for maintenance purposes, improving lighting quality-which benefits worker health and safety-and integrating with the demand-response server to reduce peak load. "Networked Lighting Controls, which already support direct energy savings through automated switching and dimming of light fixtures, can further improve their payback by taking into account non-energy benefits enabled by the sys- tem through productivity gains, safety and security enhancements, extended equipment life cycles, and more in cost-benefit calculations," said Stuart Ber-jansky, technical director for DLC.
