DOE is focused on identifying opportunities for the optimi­zation of tunable lighting systems -- from analyzing data collected by the lighting system, to furthering understanding of how occupants use tunable lighting controls -- and making sure that LED technology reaches its full potential for energy savings and other benefits, such as improved control and quality. At the same time, growing interest in human health in the built environment is leading building owners and occupants to seek healthier buildings. This trend has aligned with rapid advances in LED technology, allowing for more control of light in the built environment than ever before. DOE is engaging with the researchers investigating biological response to light, to advance our understanding of the visual and nonvisual response of building occupants to various aspects of advanced lighting systems. Much of the existing research has occurred in controlled laboratory environments, and DOE seeks to better understand this relationship in realistic settings using the GATEWAY precedent for field evaluations.
