Abstract: This contribution describes a simulation-based method for the design and evaluation of building control strategies for new planned buildings. The approach consists of a combination of a digital twin of the real building and its HVAC system, modelled as a physical Modelica model and the openHAB software package, for the implementation of correspondent building control strategies. For this purpose, openHAB and the Modelica model is bi-directional coupled in real-time. In this way, new control strategies can be tested and improved under consideration of the dynamic system behavior in the building design phase. If the system behavior of the building simulation model is close enough to the real system, the digital twin can be substituted afterwards by the built building and the control strategy will behave during the operation of the real system almost unchanged.
