The wind-induced pressure loads are affected by a broad spectrum of elements involving flow conditions, buildings geometry, or neighbourhoods. Computational fluid dynamics is a useful device used to estimate pressure distribution. The aim of this research is a detailed assessment of the use of numerical calculation (RANS) for forecasting wind-induced pressure loads on buildings arranged in tandem located in the built-up area. The approach of this work was to determine the pressure loads on the walls of rectangular objects, which were the simplified models of buildings located in the ground-level zone. The important task was to estimate the impact of distance between obstacles on the pressure loads on their surfaces. It was found that when changing the distance between buildings the pressure distribution on the downstream object varies significantly. Additionally, for defined geometrical parameters, the influence of inflow angle was analysed. The obtained results demonstrate and confirm that RANS numerical calculations, in spite of all their limits, can accurately modeling the pressure distribution on buildings.
