On the other hand, pedestrian comfort depends also from the wind conditions which are strongly guided by these man-and high-rise buildings in a dense urban context. A 3D model was used to perform simulation analysis in order to evaluate the effect of wind around the simulation domain. For this simulation was used a Computational Fluid Dynamics software which was compatible with the 3D model. Results show that high rise buildings can prevent at large the ventilation. Also, high rise structures with considerable straight surfaces should be analyzed otherwise they can turn in extremely unfavorable to natural ventilation. Architectural forms and urban corridors should be examined considering comfort ventilation perspective, otherwise, they can turn to an unpleasant experience, especially to people in the ground level. The prediction of wind effects should be assessed during the design phases, where changes in projects are frequent.
