摘　　要：在方案设计阶段,合理的建筑设计可充分挖掘自然通风潜力,最大限度地利用当地气候资源,对实现低碳建筑设计具有重要意义。针对重庆市某拟建节能办公建筑,应用PHOENICS软件重点对该建筑不同外墙开口和内部隔断方案进行自然通风的数值模拟。通过模拟结果的对比分析,得出了较优的隔断、进风和出风口方式方案,使室内绝大部分区域的空气龄低于5 min,为该建筑的自然通风设计提供了参考方案和技术支持。Reasonable design Of a building in the conceptual phase can fully exploit the potential of natural ventilation and make maximal use of local climatic resources. It is meaningful for design of low-carbon architecture. With one office building to be built as an example, the influence of the external openings and internal partitions on the indoor natural ventilation effect was numerically simulated. It was found that the mean wind velocity and impact factor of nature wind were larger by adopted the optimized scheme. The age of air indoor was mostly less than 5 min. And the effect of natural ventilation was well, which provided reference and technical basis for the natural ventilation design of the building.
