An example of model evaluation by experimental comparison: pollutant spread in an apartment

Within Annex 23 ('Multizone Air Flow Modelling') of the LEA (International Energy Agency), a large part of the effort went to the evaluation of the de veloped simulation tool COMIS [J.-M. Furbringer, C.-A. Roulet, R. Borchiell ini, Evaluation of COMIS, IEA Annex 23: Multizone Air Flow Modelling, LESO- EPFL, Lausanne, 1996; J.-M. Furbringer, C.-A. Roulet, R. Borchiellini, Eval uation of COMIS -appendices, IEA Annex 23: Multizone Air Flow Modelling, LE SO-EPFL, Lausanne, 1996]. The purpose of this work was to examine the relia bility of the output of the program and also the impact of the input parame ters on the simulation result. Therefore, the program was tested in differe nt ways, for several cases with sometimes strongly different input paramete rs. Two cases were examined in detail by the BBRI. (Belgian Building Resear ch Institute): Spread of contaminants in an apartment with natural ventilation: this case will be discussed in this text. Single-sided ventilation in a PASSYS-test cell. Thanks to all these different simulations, one can have an increased confid ence in the simulation tool COMIS. More exactly, it gives an idea of the po ssibilities and limitations of the tool.
