【摘要】 夏热冬暖地区夏季能耗较高,其建筑节能的重点是降低夏季的空调能耗。自然通风可以为居住建筑改善空气品质,并最大限度的减少空调使用时间,改善室内热环境;而建筑外遮阳技术也可以有效降低空调能耗,同样可以减少空调使用时间。在夏热冬暖地区自然通风和建筑外遮阳技术是建筑节能的关键技术和重要组成部分。更多还原

【Abstract】 Buildings energy consumption is very high in summer of hot summer and warm winter zone, so it is the emphases to reduce the building energy consumption in the hot summer and warm winter zone for energy-saving. Natural ventilation can improve the indoor air quality of residential buildings and shorten air-conditioning hour maximumly. And the external sunshade can improve the indoor thermal environment and reduce the building energy consumption. Therefore, natural ventilation and external sunshade are the key technologies and important components in the hot summer and warm winter zone for energy-saving.更多还原
