摘　　要：建筑外遮阳是建筑节能的重要措施,但单一、不当的遮阳形式却可能阻碍房间的隔热、采光、通风和视野等,从而降低室内环境舒适性。以综合节能为目标,提出建筑外遮阳优化设计思路及方法,以重庆地区为例,基于气候特征分析研究南向和西向窗口综合性能好的外遮阳形式。模拟一般办公空间搭建外遮阳实验平台,对其隔热、采光和通风效果进行实地测试和检验。结果表明,优化后的外遮阳装置不仅遮阳和降温效果明显,而且,室内采光、通风及视野效果良好,具有综合节能的作用。Architectural external shading is an important measure for building energy saving,but single and improper shading may hinder the heat insulation,lighting,ventilation and vision of the room,and reduce the comfort of indoor environment.With the aim of comprehensive energy saving,this paper put forward the optimal design method of architectural external shading.Taking Chongqing as an example,based on the analysis of climate characteristics,the exterior shading forms of south and west orientation with good comprehensive performance were studied.Simulating the general office space to build an experimental platform of composite external shading,its insulation,shading,lighting and ventilation effects were tested and inspected.The results show that the optimized external shading devices have good lighting,ventilation and vision effects as well as obvious cooling effect.
