Résumé : |
In order to select the most influential parameters of a building thermal model involving 390 parameters, an exact differential screening analysis is performed. After one single run of the model, only 23 parameters are retained. For the analysed configuration, results show that : (1) prominent parameter effects are found to be strongly influenced by the exchanged heat flows ; (2) depending on the nature of the materials and their thermal properties (thermal resistivity, storage capabilities…) thermophysical parameter effects have characteristic time evolutions ; (3) the influential parameters ( with respect to the inner air temperature) are all related to the building components hanving the largest heat exchange with the air cell. In addition, exact differential analysis has demonstrated its efficiency in predicting model output uncertainty band. |
