Due to the importance of natural phenomena in human life, investigation and study of these phenomena has always been of interest. The aim of this study is to investigate the stack effect that occurs in all buildings, although it is more noticeable in high-rise buildings. Due to the importance of this phenomenon in the energy consumption of high-rise buildings, in this research, these types of buildings have been studied. Due to the importance of the influence of the cross-section of buildings on the occurrence and behavior of this phenomenon, therefore, elliptical, triangular and rectangular cross-sections with the same surface have been examined and by comparing the results, different cross-sections have been evaluated and compared. The simulation of this phenomenon has been done in Fluent software and the analytical results have been compared, which shows a good match. The results show that the elliptical cross-section, according to its geometry and aerodynamic conditions, has the best performance in terms of the amount of additional pressure required to create positive pressure and energy consumption.
