Abstract

Building-downwash has recently captured the attention of environmental researchers since it may represent an undervalued danger in urban environments. Especially in certain meteorological conditions, buildings act as barriers triggering pollutant accumulation that will then increase concentration values. One of the main fostering conditions is the source altitude with respect to buildings while main roads represent important linear sources below building levels. In this work we highlight the influence of the building-downwash effect on pollution dispersion in an urban environment. In order to do this, we have run several simulations by the Aermod model coupled with the BPIP sub-model for building down-wash boundary conditions. The simulation area is an important street in the centre of Ancona, Italy. The period we
