Résumé
An experimentally validated numerical method for evaluating the suitability of an urban
design with regard to its capacity to provide the optimum air quality for its occupants through the
confined outdoor spaces is proposed. Eight possible confined outdoor spaces are defined according
to their position with regard to the built elements, laterally delimited by the envelope surfaces of the
neighbouring buildings. This work focuses on the definition of a procedure capable of analysing
outdoor air change quality according to the age-of-the-air concept. The obtained results show that
the confined outdoor spaces that are exposed to the wind action are more predisposed to reduce the
mean age-of-the-air that they contain. For the analysed cases, a considerable improvement of up to
78.68% in the air change quality can be obtained by taking into account wind exposure criteria in
relation to its shape and urban density, which is classified for this purpose.
