摘　　要：自然通风是一种健康及高效的绿色建筑技术手段。文章基于绿色建筑理念,利用PHOENICS软件,对某典型建筑大厅门斗的自然通风情况进行了定量分析,通过改变门斗长宽比,对比厅内自然通风效果情况。结果表明:杭州地区过渡季节,建筑大厅不同长宽比的门斗会对厅内自然通风效果产生影响,且当门斗采用长宽比为4:1时室内通风情况最佳;当采用长宽比为2:1时,则不利于室内自然通风,从而为今后建筑入口设计提供一些理论参考。Natural ventilation is a healthy and efficient means of green building technology.Based on the concept of green building,this paper uses PHOENICS software to simulate and analyze the natural ventilation of the door bucket in a typical building hall,and compares the natural ventilation effect in the hall by changing the length to width ratio of the door bucket.The results show that in the transitional season in Hangzhou,the door bucket with different length to width ratio will affect the natural ventilation effect in the hall,and the indoor ventilation is the best when the length to width ratio is 4:1;When the ratio is 2:1,it is not suitable for natural ventilation.So as to provide some theoretical references for the design of building entrance in the future.
