单位面积供热能耗的家庭建筑面积效应
Effect of Household Floor Area on Heating Energy Consumption per Unit Area
摘要
Abstract
Based on the statistical yearbook data,the calculation method of urban residential heating energy consumption is put forward,and the surrogate model for heating energy consumption per unit area(referred to as the surrogate model)based on STIRPAT model is established.The sample of residential heating energy consumption data from the statistical yearbook is used to train and obtain the standardized coefficients of the surrogate model.After being tested with a validation set sample,the root mean square error(RMSE)of the surrogate model is 1.99 kg/m2,the coefficient of varia-tion of the root mean square error is 16.37％,the nor-malized average deviation is 3.36％,which proves that the surrogate model has high prediction accuracy and strong generalization performance.From 2012 to 2020,if the promotion effect of household floor area on the re-duction of heating energy consumption per unit area is ignored,the reduction level of heating energy consump-tion per unit area will be overestimated by 4.07％.It is recommended that areas with small household building areas prioritize the use of heating energy intensity evaluation indicators based on household building area.This indicator can effectively avoid the promoting effect of household building area on the decrease of heating energy consumption per unit area.关键词
