Data needs for the purpose of air infiltration computer code validation.

A simplified model of air infiltration has been developed at Lawrence Berkeley Laboratory, in order to expand the use of air flow calculation techniques outside the field of research. The validity of the programme must be checked. Benefit has been gained from work dedicated to the same problem in the field of building thermal analysis. Following this idea, a detailed validation methodology is proposed. Progression in the complexity of the modelled structures, use of high accuracy data are sine qua non to this task. Moreover, for a simplified model, an approach based on Monte-Carlo techniques appears necessary. The validation of the developed simplified model will be carried out by way of a joint research project between EPFL and LBL. It is hoped that the validation procedure, proposed in this paper, will be used to validate other air infiltration calculation techniques.
