Summary

Indoor thermal discomfort in summertime is amplified in city centre by the urban heat island (UHI) effect. Traditional buildings in Mediterranean cities are organized according to some typical patterns enhancing the thermal comfort. Narrow streets, like urban canyons, are confined and can be valuable for better solar protections and lower temperature levels. Meanwhile, air conditioning systems are developing and participate with others anthropogenic sources to the UHI effect emphasize. The objective of this study is to define the interactions between urban microclimate, buildings and its air conditioning energy demand, by simulation of heat and mass transfer in the case of an urban canyon street in Athens. Heat and mass transfers are assessed with empirical and zonal models which are coupled with the functioning of the air conditioning system. The simulations are computed on a one month period during summer so the dynamical behaviour of the system can be assessed, and compared with experimental data. The obtained results highlight a strong interaction between the urban microclimate and the air conditioning system.
