关于中国建筑节能气候分区的探讨
Discussion of climatic regions of building energy efficiency in China
摘要：
根据气候与建筑能耗的关系，确定了影响建筑能耗的气候要素，提出以HDD18、CDD26为1级指标，冬季太阳辐射量、夏季相对湿度、最冷月平均温度等为2级指标;划分了中国建筑节能气候分区，将全国划分为8个区，并论述了各个分区的气候特点。

Abstract：
Based on the relationship between the climate and building energy consumption, determines the climatic factors influencing the building energy consumption. Taking heating degree days based on 18 ℃ and cooling degree days based on 26 ℃ as the primary indexes, solar radiation in winter, relative humidity in summer and mean temperature in coldest month as the secondary indexes, divides the whole country into eight climatic regions of building energy efficiency and discusses the climatic characteristics of each region.
