Thermal behaviour of buildings: modelling the impact of urban heat island
The development of air conditioning systems for summertime thermal comfort participates in an increasing proportion in the building energy demand. The objective of this study is to define the interactions between the urban microclimate, buildings and their air conditioning energy demand by the simulation of heat and mass transfer in the typical case of an urban street canyon. A zonal model is chosen for heat and mass transfer modelling. This approach, midway between accurate fluid dynamics codes and simple nodal models, allows us to describe, accurately enough for building energy study, thermal and wind speed parameters in the street. A coupled study of wind and natural convection in a street canyon is completed on a 28 days period. The consequences of heat and mass transfer in the canyon on the heat island evolution are discussed, as on the building energy demand.
