This paper presents the architecture and a prototypical implementation of a daylight-responsive illumination systems control in buildings that makes use of real-time sensing and lighting simulation. To arrive at control decisions, the controller application possesses an internal digital representation involving models of the room, the sky (context) and the occupancy. The room model is updated dynamically using an optically-based location-sensing system. The sky model is generated on a real-time basis using calibrated digital photography. The controller application predicts, compares, and ranks the implications of these alternative control actions based on preferences set by the users and/or facility manager. The alternative control option with the most desirable performance is selected and can be then realized either via direct instruction to the relevant actuator or communicated to the user as a control action recommendation.
