The research presented in this paper focuses on the implementation and testing of an innovative
(integrated and intelligent) model-based (simulation-assisted) strategy for effective passive room cooling in
buildings. 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 is applied. To enhance the prediction capability of the simulation
model, it was subjected to a systematic calibration effort. Thereby, initial model input assumptions were modified
based on the results of a comparison between the model´s initial predictions with the respective measured
performance indicators. Results suggest that a predictive control approach that uses a calibrated simulation
engine can optimize the operation of windows toward reducing overheating tendencies in buildings.
