Exploring model-based reasoning in lighting systems control

Computational lighting modeling has traditionally concentrated on the build ing design phase. We argue that lighting simulation can also effectively ap ply to the building operation phase. To demonstrate this potential, we expl ore a simulation-assisted lighting control strategy. We specifically demons trate how a daylight simulation tool is applied to predict task illuminance and luminance levels in lieu of an extended sensing system, thus providing the necessary input information for algorithms towards real-time control o f buildings' lighting systems.
