广州地区居住建筑遮阳对节能率的影响及其优化设计研究

Study on the Influence of Shading on Energy Saving Rate of Residential Buildings in Guangzhou and Its Optimal Design

有效的遮阳技术措施对于广州地区居住建筑的能耗减少意义重大。本文选取屋顶传热系数、外墙传热系数、综合遮阳系数、外窗传热系数等四个主要要素,以全年平均冷能耗为评价目标,通过正交试验设计出组合方案,并利用DeST软件进行能耗模拟,探究影响该地区住宅建筑能耗的关键性因素。进而以广州地区某住宅西向客厅为例,使用Ecotect软件对五种类型百叶遮阳进行模拟分析,探究各类遮阳的作用效果,最后综合考虑并提出有利于室内光环境和节能的遮阳技术措施。

Effective shading technology measures are of great significance for reducing energy consumption of residential buildings in Guangzhou.In this paper,four main factors of roof heat transfer coefficient,external wall heat transfer coefficient,comprehensive shading coefficient and external window heat transfer coefficient are selected.Taking the annual average cold energy consumption as the evaluation target,the combination scheme is designed by orthogonal test,and the energy consumption simulation is carried out by DeST software to explore the key factors affecting the energy consumption of residential buildings in the region.Taking a residential west living room in Guangzhou as an example,this paper uses Ecotect software to simulate and analyze five types of shutter shading,and explores its influence on lighting and shading effect.Finally,the shading technical measures conducive to indoor light environment and energy conservation are comprehensively considered and proposed.
