For about ten years several research groups at ETH have been investigating the design and implementation of advanced techniques for the control of indoor climate and their impact on energy use and comfort. In my talk I will summarize these efforts on building modeling and identification, and the use of weather, occupancy and utility price forecasts for control, including information on the uncertainty (stochastic and robust control). I will also describe an on-going project on implementing and testing a predictive control scheme on a large office building in Basel.
