通过分析影响建筑冷热耗量的气候指标,提出了以采暖度日数HDD18、空调度日数CDD26、最冷月平均温度、最热月平均温度、冬季太阳辐射热量、夏季太阳辐射热量、冬季含湿量和夏季含湿量8个气候指标作为建筑节能气候区划指标,采用主成分分析与聚类分析相结合的区划方法对我国270个城市进行了建筑节能气候区划,划分为严寒干热高辐区、严寒凉爽高辐区、严寒无夏区、寒冷微热区、温和炎热湿润区、温和凉爽区和阴冷湿热区,介绍了这7个气候区的主要气候特征和主要的地理范围,明确了各区的建筑节能重点和适宜的技术策略。
Based on the analysis of the climatic indexes that affect the heat and cooling consumption of buildings, the paper presents the measures of heating degree days HDD18, air conditioning day days CDD26, the coldest month average temperature, the warmest month average temperature, the winter solar radiation heat, the summer solar radiation heat, Volume and summer moisture content of 8 climate indicators as a building energy-saving climate zoning indicators, the use of principal component analysis and cluster analysis of the zoning method of China’s 270 cities were building energy-saving climate zoning, divided into cold and dry heat radiation zone , Cold and cool high-radiation zone, no summer cold zone, cold micro-hot zone, mild hot and humid zone, mild cool zone and cold and damp and hot zone. The main climatic characteristics and main geographical ranges of the seven climatic zones are introduced. The focus of building energy efficiency and appropriate technical strategy.
