Eight possible confined outdoor spaces are defined accordingto their position with regard to the built elements, laterally delimited by the envelope surfaces of theneighbouring buildings. This work focuses on the definition of a procedure capable of analysingoutdoor air change quality according to the age-of-the-air concept. The obtained results show thatthe confined outdoor spaces that are exposed to the wind action are more predisposed to reduce themean age-of-the-air that they contain. For the analysed cases, a considerable improvement of up to78.68% in the air change quality can be obtained by taking into account wind exposure criteria inrelation to its shape and urban density, which is classified for this purpose.
