较之于其他公共建筑，医用建筑对室内空气品质和新风量要求较高，如果仅通过 机械通风，往往能耗需求量大． 利用竖井空间改善医用建筑的室内自然通风，对岭南地区 而言，这种方式无论在环境卫生还是在生态节能方面均具有潜力． 本研究以岭南地区的医 用建筑为样本对象，根据竖井空间的布局建立计算模型，采用 CFD 技术对其过渡季节的 风环境作出模拟分析． 结果表明:竖井空间方位和相对位置的合理设置可以改善医用建筑 通风的舒适性和均匀性，从而在不借助机械通风的情况下使通风环境达到人体舒适范围; 竖井空间的合理设置能在满足建筑布局舒展性的同时有效地缩短医疗流线，充分利用建 筑用地;竖井空间的合理植入还有利于遮阳，是解决扩容过程中新老建筑之间通风采光问 题的有效手段． 

Hospital buildings require better indoor air quality and greater fresh air volume compared to other types of public buildings． Andmechanical ventilation needs large energy consumption． For Lingnan area，the indoor natural ventilation of shaft space can be well utilized by hospital buildings． The method is both environmental and energy saving． Taking hospital buildings in Lingnan for example，a computing model based on the layout of the shaft space set was built，and the wind environment during transitional seasons was analyzed by using CFD technology． The results show that the rational spatial orientation and the relative position relations of the shaft setting can improve the ventilation comfort and uniformity of hospital buildings． Even without mechanical ventilation，it can help keep human body comfortable in ventilated environment． Proper shaft space setting can effectively shorten the medical streamline，and make full use of the building land． The reasonable implantation of shaft space is also conducive to shading，which is an effective means to solve the ventilation and lighting problems between new and old buildings in the process of expansion．
