This study uses validated Large-eddy simulations to investigate the impact of the building exposure on the flow field around the principal building placed in the turbulent atmospheric boundary layer. The prismatic 1:3 square high-rise building model is analysed, considering three configurations: one isolated building model and two group arrangements of five geometrically identical buildings. Four exposure cases are singled out: model directly exposed to the wind, in single and group arrangement, partly exposed model placed in the channel between four buildings and completely shaded one by the building in front. Flow visualisation above the roof shows a strong dependency on the size of the separation zone and the exposure level. The results will be further used to predict the wind energy potential around buildings as well as the pedestrian level winds.
