南海岛屿气象参数与建筑能耗分析

Meteorological parameters and building energy consumption analysis of South China Sea islands

分析了海洋气候下东沙群岛、西沙群岛和南沙群岛中部分岛屿的温湿度、风速风向和太阳辐射等气象参数特征,并与临近陆地城市(广州、三亚)进行对比;通过DeST软件模拟比较了典型居住建筑和办公建筑在陆地站点和岛礁站点的能耗差异。结果表明,岛礁温湿度较高且年较差小,全年保持相对高温高湿,年平均风速高于陆地站点,太阳辐射多分布在强辐射范围,对于居住建筑和办公建筑岛礁建筑能耗均远高于陆地。

The meteorological parameters such as temperature,humidity,wind speed,wind direction and solar radiation in the Dongsha Islands,Xisha Islands and Nansha Islands were analyzed and compared with the neighboring land cities（Guangzhou and Sanya）.The difference of energy consumption between typical residential and office buildings at land and island reef sites were compared by DeST.The results indicated that the islands are relatively in high temperature and humidity all the year round.The annual average wind speed is higher than that of the land site.The solar radiation is mostly intense radiation.The energy consumption of islands are much higher than land sites for both residential and the office buildings.
