English abstract:
The research presented in this paper focuses on the virtual implementation and testing of an
innovative (integrated and intelligent) model-based (simulation-assisted) strategy for effective
passive room cooling in buildings. To test this strategy, we generated simulation models of an
office and a residential building in Austria. A control scheme was conceived as follows: at a
specific point in time in a typical summer day, the control unit applies simulation to predict
how various window operation regimes would affect the indoor temperature over the course
of the following day. Thereby, as microclimatic boundary conditions necessary for simulation
runs, weather forecast data were applied. Results show that optimized operation of windows
can significantly reduce the overheating tendency in buildings. To address the implications of
weather forecast errors, predicted and measured external data were compared.
