摘要/Abstract

摘要： 选择中国不同气候区的代表城市哈尔滨、天津、上海和广州，模拟了办公建筑1961—2012年供热和制冷能耗，分析了度日与能耗的相关性，进而评估了用度日分析建筑能耗的可靠性。结果表明：哈尔滨、天津和上海办公建筑供热能耗与采暖度日有显著的线性正相关关系，而且度日可以解释供热能耗变化95%以上的原因。采暖度日可以较为可靠的反映不同气候区的供热能耗变化特征，因此可用于研究气候变化对供热能耗影响。相反，制冷度日反映制冷能耗变化特征的精确性较差，用其研究制冷能耗将有较大偏差。制冷度日不能精确反映制冷能耗主要是因为夏季制冷能耗受气温、湿度、辐射等多要素共同影响，而冬季供热能耗主要受气温影响。

Abstract: This study revealed the reliability of degree days for reflecting the office building energy consumption by simulating the energy consumption from 1961 to 2012 and then investigating the correlations between the heating and cooling energy consumption and degree days in four cities including Harbin,Tianjin,Shanghai and Guangzhou representing different climate zones in China.The results show that there are significantly linear positive correlations between the heating energy consumption and heating degree days in Harbin,Tianjin and Shanghai and degree days can explain up to 95% variations of heating energy consumption,implying that heating degree days can be efficiently used to reflect the characteristics of the heating energy consumption and therefore to study the impact of climate change on heating energy consumption.On the contrary,the cooling degree days are unable to accurately reflect the variations of cooling energy consumption.By analyzing the relationships between energy consumption and relevant climatic factors,the heating energy consumption is dominantly affected by the temperature in winter while the cooling energy consumption is related to various factors such as temperature,humidity and radiation in summer,especially in the cities of hot climate zone.
