Abstract: In this paper, we identify and validate multi-zone grey box models with real-world temperature measurements. We obtain the temperature measurements from temperature sensors in each room of an experimental building, designed as a single-family home. The number of thermal zones determines the complexity of the model. The investigation of complex models is beneficial for advanced control scenarios. These complex models allow different heating scenarios in different rooms, e.g. in the case of residential buildings: living room, bedroom, or bathroom. Moreover, the different heating scenarios can also consider different influences of solar radiation, depending on the sun-orientation of the rooms. Finally, we analyze the performance of the different models to recommend the model complexity for occupants' requirements on the thermal environment and Demand-Response (DR) with Model Predictive Control (MPC).
