A simplified coupled model for thermal behaviour and air flows simulation in urban spaces

The studies presented here aim at defining and setting out a calculation code allowing the prediction of outdoor ambient thermal quality. Designers of urban spaces are expecting more specialized information such as skilled rules which may be achieved by the presented code, at present in process of development. The physical system is identified as being representative of the urban network of an average town like Saint-Denis, Reunion Island (about 60 000 inhabitants). The calculation code, made up by assembling different models, describes the thermal behaviour of the physical system.
