In this research, a new numerical approach which is capable of modifying the shape of three dimensional massive bodies like tall buildings respect to aerodynamic loads is presented; therefore, the aerodynamic forces are improved; consequently, the comfortability of the buildings is increased. This method is drawn into 2 parts; a numerical simulation of fluid flow and Adjoint method. As a result of it, some modifications are performed in the different parts of the building. In the primarily step, the building shape and its setting position are investigated in different flow conditions as effective parameters on the aerodynamic of buildings. Subsequently, the sensitivity level of each variable is studied on aerodynamic loads. The results illustrate that the building pattern has the highest impressments (76%) on the excited forces. In the next step, the amount of sensitivity of the fluid flow on the various areas of the tower is assessed by solving Adjoint equation in the whole fluid domain. As a result of that, some aerodynamic modifications are performed and it has been proved that the imposed loads on the tower have been declined around 31% whereas this amount of improvement is interested for designing of tall buildings.
