Daylighting has the potential to significantly reduce electrical demands created by lighting in commercial buildings. Current interior lighting systems that attempt to utilize available outdoor light do not readily adapt to changes in the external and internal environments. Not only do these systems adversely impact the occupants and lead to reduced user satisfaction; they also require extensive maintenance and upkeep. This project will develop an adaptive daylighting control system that will eliminate many of the negative characteristics of current daylighting technology. This system will be capable of adapting to the changing occupancy configuration as well as to seasonal and other external lighting variations. Phase I will develop and field a robust, adaptive daylighting control system. It will use a computer-based communication and control system and a novel sensor system to maximize both occupant comfort and energy efficiency.
Commercial Applications and Other Benefits as described by the awardee: This system should have application to both commercial and residential buildings. The technology will lead to a daylighting control system that will facilitate the penetration and market acceptance of energy efficient systems.
