摘　　要：我国南海处于极端热湿气候区,为顺应岛礁开发建设与可持续发展,建筑应更多地采取被动式策略以降低能耗。虽然南海岛礁常年高温、高湿,但气温日较差与年较差小、风力大,建筑具有潜在的自然通风能力。应用建筑气候学相关原理,以标准有效温度SET作为评价指标与方法,综合温度、湿度、风速等因素,全面评价岛礁的自然通风潜力。选取南海地区6座典型位置的岛礁,采用参数化方法对标准有效温度进行计算分析,得出满足热舒适要求的标准有效温度全年时间占比,并评价其自然通风潜力。同时研究了温度、风速对标准有效温度的影响。South China Sea is in extreme hot-humid climate.In order to meet the sustainable development demands of building on the Islands of South China Sea,more passive methods should be adopted.Buildings on the islands of South China Sea have potential of natural ventilation because of extreme hot-humid climate has steady temperature and strong wind,even though the local climate is high temperature and high humidity.Using the theory of Bioclimatic Architecture and Standard Effective Temperature(SET)as the assessment index,integrating the temperature,humidity and velocity,the potential of natural ventilation is evaluated.Six typical islands in typical locations in the South China Sea are selected,a parameterized method is used to calculate and analyze Standard Effective Temperature.The percentage of SET that meets the thermal comfort requirements is obtained throughout the year,and its natural ventilation potential is evaluated.The influence of temperature and wind speed on the SET is studied.
