Contemporary facades represent lightweight, most frequently transparent membranes whose design and construction is a complex and demanding task. The research subject of this dissertation are curtain walls and their complex analysis in actual conditions. Wind, as a dominant load, was considered as dynamic, and it was modeled with the aid of numerical fluid dynamics. Regarding the variation of wind velocity with the height, the roughness of terrain was taken into consideration by modeling the atmospheric boundary layer. A building model was created, with the b:d:h ≈ 1:1:2.5 dimensional ratio. This building was analyzed through four groups of models. Model A, B, C and D group comprised wind action at the angle of 00, 150, 300 and 450, respectively. Two turbulent models were used, RNG k-ε and SST k-ω. The obtained results were presented through dimensionless coefficients of pressure and compared with the standing standards and results of experimental research. Recommendations for creation of
