[en] A method based upon a calibrated model of building is proposed here to evaluate the performance in terms of thermal comfort during summer in a passive house. A model of the house was developed and this model was used to determine optimal solutions (cost and efficiency) to reduce or avoid the overheating that could occur in the building. The first step of this work consisted in the calibration of the thermal response of the simulation building model by comparison with the internal temperatures measured in the passive house during summer period. The simulations took into account the occupancy in the house and several other parameters in order to match the temperature sensors data of the house. These parameters were adjusted thanks to sensitivity analysis. An assessment of the accuracy of the simulated model was conducted by computation of sensitivity indicators. When the results of calibration showed a good matching between reference and simulated buildings the simulations were used to assess the best solution to reduce the overheating in passive house rooms which is occurring when the percentage of overheating time is over 5% (Passive House Platform standard in Belgium).
