This paper describes a comparison of two different solutions of a standard problem in building aerodynamics, i.e. the load of a cube-shaped object exposed to the effects of an air flow field. Two problems are discussed in this article. First is the solution of the flow field with the constant wind velocity and low turbulence intensity, while the second problem is about the flow in the simulated atmospheric boundary layer, i.e. the flow field with the high intensity of the turbulence and with the gradient velocity. Physical modelling takes place in the climatic wind tunnel of the Institute of Theoretic and Applied Mechanics AS CR in Telč and numerical modelling is solved using the Ansys Fluent software at the Faculty of Civil Engineering of VŠB – Technical University of Ostrava.
