本文基于广州市商场建筑的能耗统计工作,抽样分析了该地区商场建筑的分类分项能耗,对其单位建筑面积能耗随月份的变化关系进行了分析拟合。同时,通过主成分分析确定了影响商场建筑能耗的基本因素。在提取主成分的基础上,经过二次回归分析,建立了商场建筑能耗估算模型,并检验了模型误差。本文从宏观角度为广州地区商场建筑能源侧管理和建筑节能提供了参考和依据。
Based on the energy consumption statistics of Guangzhou shopping malls, this paper analyzes the classification energy consumption of the malls in this area by sampling and analyzes the relationship between energy consumption per unit area and monthly changes. At the same time, the main factors that influence the energy consumption of shopping malls are determined by principal component analysis. Based on the principal component extraction, through the second-order regression analysis, the building energy consumption estimation model of shopping mall was established and the model error was tested. This article provides a reference and basis for building energy side management and building energy saving in Guangzhou shopping malls from a macro perspective.
