摘要
商业建筑在建筑行业中是减排工作的重点。新加坡在建筑能耗管理和节能减排工作方面可为我国提供重要的参考意义。基于新加坡商业建筑的能耗表现数据,通过箱线图和Spearman相关系数分析方法,分析了新加坡商业建筑的能耗特征和影响因素。研究发现新加坡不同功能类型的商业建筑中能耗波动和能耗水平存在较大差异,能耗波动幅度由大到小依次为零售类、办公类、混合类、酒店类,能耗水平由高至低依次为零售类、混合类、酒店类、办公类。新加坡商业建筑能耗与竣工年份、使用空调面积占比、LED使用率显著相关,且均为正相关关系。此外,不同的绿色认证状态和各种功能类型的建筑能耗影响因素也各有不同。研究结果可作为参考依据,对我国商业建筑能耗定额和节能指导工作做出启示。
Commercial buildings are the focus of emission reduction in the construction industry.Singapore has important experience for China in terms of building energy consumption management and energy saving and emission reduction.Based on the energy consumption data of commercial buildings in Singapore,the energy consumption characteristics and influential factors of commercial buildings are explored through boxplots analysis and Spearman correlation coefficient analysis.It is found that there are large differences in energy consumption fluctuations and energy consumption levels among different functional types of commercial buildings in Singapore,with energy consumption fluctuations ranging from large to small in the order of retail building,office,mixed building,and hotel,and energy consumption levels ranging from high to low in the order of retail building,mixed building,hotel,and office.The energy consumption of commercial buildings in Singapore is significantly correlated with the year of completion,the percentage of air-conditioned area,and the LED usage rate,and all of them are positively correlated.In addition,the factors influencing the energy consumption of different green certification status and various functional types of buildings are also different.The results of the study can be used as a reference to make insights into the energy quota and energy saving guidance for commercial buildings in China.
