# How to Calculate Wind Load on a Building. BlogAECHow to Calculate Wind Load on a Building. In this challenging environment, computational fluid dynamics (CFD) has become an effective tool that helps architects and civil engineers reduce uncertainty and make informed decisions early in the design process, by allowing them to predict the physical performance of their buildings under different conditions. Wind analysis is the evaluation of the dynamic effect of wind on a structure and is used for optimizing designs to best mitigate these effects. It is the task of architects and design engineers to ensure a safe, sustainable, and cost-efficient design by utilizing wind engineering studies and taking into account building aerodynamics. ## Wind Load Design. In this case, we investigated the wind load effects and discussed the importance of mitigating vortex shedding in tall buildings. The results show the pressure loading and velocity contours for the initial design and the comparison of the dynamic wind load effects of vortex shedding for the modified design.

Journal of Energy and Power Technology. *Journal of Energy and Power Technology* focuses on all aspects of energy and power. *Journal of Energy and Power Technology (JEPT)* is an international peer-reviewed **Open Access** journal published quarterly online by LIDSEN Publishing Inc. This periodical is dedicated to providing a unique, peer-reviewed, multi-disciplinary platform for researchers, scientists and engineers in academia, research institutions, government agencies and industry. The inlet velocity boundary condition was defined as a uniform inlet wind speed and then as a Normal Wind Profile (NWP). Three large wind speeds of 25 m/s, 40 m/s and 50 m/s were tested with the aid of the RANS equations and the Shear Stress Transport (SST) turbulence model. Overall, the NWP method was found to produce larger wind forces and moments in comparison with the uniform wind speed conditions (on average 52% and 63% higher, respectively), and its predictions were consistent with the estimations obtained using the simplified drag formula recommended by offshore standards (within approx.
