English abstract:
This paper presents the results of a recent effort to prototypically implement a new model-based approach to lighting systems control in buildings. Using real-time sensing and numeric lighting simulation, this system can dynamically control the position of window blinds and the status (on/off, dimming level) of the luminaires. The control system possesses an internal digital representation consisting of room, sky, and occupancy models. The room model entails information about geometry, furniture, location and size of windows, reflectance and transmittance properties of surfaces, as well as the position of virtual sensors, that monitor pertinent performance parameters such as illuminance levels, light distribution and is updated dynamically using an optically-based location-sensing system. The sky model can be generated on a real-time basis using calibrated digital photography.
