Abstract
Commercial daylighting systems have been shown to save up to 45 percent in electricity consumption when properly commissioned, and installed in areas with significant amounts of daylight. In practice however, these systems are greatly under leveraged. This paper details the development of an intelligent commercial lighting system designed to overcome user dissatisfaction, lost energy savings due to simple control algorithms, and high retrofit costs. An influence diagram decision framework is used to optimize demand responsive actuation decisions, resulting in improvements in user satisfaction and energy efficiency compared to existing daylighting systems. Further, the system utilizes wireless sensing and actuating technology to relieve much of the expense associated with retrofitting.
