基于ECOTECT的郑州地区办公建筑南向外遮阳模拟分析

摘要

The office building shading is analyzed from climate characteristics of Zhengzhou, the nature and requirements of the office building. The time of shading, shading methods, sunlight angle and shading angle are determined step by step. The local sunshine and shading are expounded through examples, as well as the comparative analysis on the shading ways. The external shading history in Zhengzhou is presented. The comprehensive analysis indicates the integrated shading form shall be utilized in Zhengzhou. The solar elevation angle and azimuth are different due to various geographical locations, so the ways of shading should be based on the specific circumstances.%从郑州地区气候特征、办公建筑性质与要求入手，对办公建筑遮阳进行分析研究，先后确定了遮阳时间、遮阳方式、日照角和遮阳角，并通过实例进行日照及遮阳分析，遮阳方式的对比分析，以及郑州地区外遮阳的演变历史的分析，最后进行综合分析，得出郑州地区宜采用综合遮阳形式的结论。每个地区由于地理位置不同导致太阳高度角和方位角不同，遮阳的方式应因地制宜。
