With the worsening global energy situation and climate environment, sustainable development and energy conservation have become the focus of worldwide attention. Using science and technology to promote green development has become a global consensus. In the context of sustainable green buildings, this study conducts a numerical simulation of stack ventilation for hospital street buildings based on Fluent software. First, the external-type hospital street standard model is simulated, analyzed, and validated. Then, the wind speed and temperature distribution patterns of the building are analyzed and compared with the green building design standards in China. Finally, a modified opening area method is applied to adjust the size and variations to achieve a more suitable ventilation volume. The results show that, as the building height increases in the external-type hospital street, the average indoor wind speed decreases, and the indoor temperature exhibits an upward trend in the vertical direction. After applying the modification method, the ventilation volume on each floor of the building under design conditions is nearly consistent, with an absolute value of relative error in the ventilation volume within 5.0%. This indicates that the modified building operates well under design conditions and can overcome the issue of varying indoor ventilation volumes due to height differences. %K 医院街， %K Fluent， %K 绿色建筑
