Computational evaluation of pedestrian wind comfort and wind safety around a high-rise building in an urban area

Pedestrian wind comfort is analyzed for a new shopping street area in Eindhoven city center. Wind nuisance is especially perceived around a tower of 105 m high, at an intersection of two streets. The Dutch wind nuisance standard NEN 8100 combined with CFD (Computational Fluid Dynamics) simulations is used to assess the pedestrian wind comfort. Special care is given to the grid generation and comparison of the CFD simulations with on-site wind speed measurements. The effectiveness of a series of incremental remedial measures is analyzed. A large canopy is shown to be successful in bringing the wind comfort to an acceptable level.
