2015 Intelligent Lighting Review


Lighting is a load which every facility manager and operator must consider from an energy and maintenance perspective. In most commercial buildings, lighting is approximately 30 percent of building load. Consequently, ongoing energy and maintenance cost, not just initial fixture cost, must become a consideration.


In addition, operators should evaluate how maintenance and energy costs compare with the benefits of energy efficiency (EE) and demand response (DR), as well as the grid impact of lighting and lighting controls before making a purchase decision. However, sometimes these decisions and evaluations are tricky and expensive for operators or utilities to conduct on their own. For more than 15 years, the Electric Power Research Institute (EPRI) has been researching the real-world operation and performance of lighting, as well as the necessity to resolve power quality and emissions problems that can result from the use of electronic devices. Consequently, EPRI has become a known resource for independent lighting research.
