Abstract: This paper presents a method to incorporate personalized visual preferences in real-time optimal daylighting control. A personalized shading control framework is developed to maximize occupant satisfaction while minimizing lighting energy use in daylit offices with automated shading systems. Personalized visual satisfaction utility functions were used along with modelpredicted lighting energy use to form an optimization framework with two schemes. Variation of results is presented as a function of preference profiles, occupant sensitivity to utility function, and exterior conditions. Finally, we present a new application and an interface to allow occupants to be the final decision makers in realtime balancing between their personalized visual satisfaction and energy use considerations, within dynamic optimal bounds.
