摘要:

对比分析了建筑热工设计分区、ASHRAE建筑气候区划以及基于聚类分析的气候区划在建筑节能设计气候区划中的可行性。通过对比分析发现:ASHRAE建筑气候区划方法提供了较为完备的干湿区划指标和步骤,但其冷热区划方法及指标不能区分我国云贵高原地区与长江中下游地区的气候差异。与其他2类方法不同的是,聚类分析方法将青藏高原单独划为一个气候区,其区划结果较为清晰简洁;但用于聚类的气候指标类别和数量以及确定最佳聚类数量的方法会对聚类区划结果造成较大影响,并降低该方法的客观性。

Abstract:

Compares and analyses the feasibility of building thermal design zoning, ASHRAE building climate classification and climate zoning based on cluster analysis in building energy efficiency design climate zoning. According to the comparison analysis, finds that the ASHRAE building climate classification provides relatively complete indicators and process for moisture zoning, but its thermal zoning method and indicators cannot distinguish the climate difference in China’s Yunnan-Guizhou Plateau and the middle and lower reaches of the Yangtze River. Different from the other two types of methods, the cluster analysis method puts the Tibetan Plateau as a single zone, and its zoning results are clear and concise. But the types and quantities of climate indicators used for clustering and the method of determining the optimal cluster number will have a great impact on the clustering results and reduce the objectivity of the method.
