Wind environmental conditions between two long narrow perpendicular buildings

This paper presents wind tunnel measurements of pedestrian wind conditions in passages between various configurations of two long narrow perpendicular buildings in open country exposure. The investigated parameters include passage width, building height and wind direction. The measurements were made along the passage centerline. The aim of the paper is to provide more insight in the pedestrian wind conditions in these basic building configurations, to address some contradictory statements reported in the literature and to provide experimental data for CFD validation. The results show that, for the cases investigated, the amplification factors in diverging passages are generally larger than in converging passages. It is also shown that the maximum amplification factors increase monotonically with decreasing passage width, contrary to some general building design guidelines proposed in the past for all building configurations.
