In this context, the simplicity and accuracy trade-off is particularly important. The computing time is also a strong constraint. The methodology involves physical simplifications and model order reduction. The physical simplications ensure to keep most relevant physical phenomena and sollicitations whereas the order reduction eliminates the non-significant state variables. Both steps are justified and compared to a reference model described in a one-dimensional detailed thermal model. The final model is reduced, linear and timeinvariant and described in a state-space form. The results show the accuracy of the heating and cooling load estimation (less than 2% in error) and a computing time decrease. Pages: 3490 - 3497 Paper:
