In this study, London The Shard skyscraper structure was examined under the concepts of sustainability and wind engineering dynamics. The aerodynamic examination of the building in accordance with the wind dynamics principles and the relevant CFD simulations as proof, created. In the simulations carried out in the Matlab CFD environment, the Navier Stokes equation principles with k-omega turbulance model were followed. The skyscraper model 1-1 was created in its original form and simulated under real wind data at its location in London. In the results obtained after the simulations, the velocity increased by V-3V in the first 600-800 meters distance range, in the x direction of the model, created a vortex around the structure. While the speed-vortex effects mechanisms were examined on the model by V-3V, the pressure load P within the first 25 meters in the z direction (structure height) of the model was reached to 5P, up to the limit of 280-300 meters. When it is reached to 300 meters height, a 5-fold increase in pressure was detected. In the x-direction, pressure change of the model tested. The variation of the pressure load at the rate of P - 2P was determined in the first 800-1000 meters of the model in the x-direction, and the pressure exerts a double effect in the first 800-1000 meters of the model. In addition to the norms and regulations of supertall design principles, all risk scenarios of wind, under the effect of velocity and pressure need to be simulated before safe construction.
