广州地区某小学外遮阳优化设计研究

Study on Optimization Design of External Shading for a Primary School in Guangzhou

在提高教育建筑环境品质和发展低碳可持续建筑的趋势下,小学建筑的舒适和节能需求不断提高。合理的外遮阳设计可以改善室内舒适度、减少建筑能耗,但相关研究在夏热冬暖地区的小学建筑较少。本文以广州地区某小学为例,采用参数化方法建立优化设计平台,模拟分析外遮阳对非空调房间热舒适、通风和光舒适的影响,进而探究外遮阳对空调房间的能耗影响。通过综合判断,从中找到垂直百叶遮阳角度和水平式遮阳与穿顶间距的较优设计方案,为夏热冬暖地区小学建筑外遮阳的合理设计提供参考。

In the trend of improving the quality of educational building environments and promoting the development of low-carbon buildings, there is an increasing demand for comfort and energy efficiency in primary school buildings. Reasonable external shading design can enhance indoor comfort and reduce building energy consumption. However, there is limited research available on the application of external shading in primary school buildings located in hot summer and warm winter areas. Taking a primary school in Guangzhou as an example, this paper built an optimization design platform with a parametric method, conducted a simulation analysis of the impact of external shading on thermal comfort, ventilation, and lighting comfort in non-air-conditioned rooms, and further explored the influence of external shading on energy consumption in air-conditioned rooms. Through comprehensive evaluation, the study identified the most suitable design schemes for the angle of vertical louver shading and the distance between horizontal shading and the window top, to provide reference for the design of external shading in primary school buildings located in hot summer and warm winter areas.
