建筑能耗占总能耗的比例很大,降低建筑能耗是建筑节能研究的重点,采用外遮阳是降低建筑能耗的有效手段,对此进行设计研究具有重要的现实意义。本文从遮阳对建筑节能的影响入手,分析了遮阳形式及设计原则,并结合建筑遮阳技术的实际应用案例,提出了现代遮阳设计中应该考虑的问题和注意事项。 The proportion of energy consumption in buildings accounts for a large proportion of the total energy consumption. Reducing building energy consumption is the focus of research on building energy efficiency. Using exterior shade is an effective means to reduce building energy consumption. Therefore, it is of great practical significance to design and study this project. Based on the influence of sunshade on building energy efficiency, this paper analyzes the forms and design principles of sunshade, and puts forward the problems and precautions which should be considered in the design of sunshade.
