摘　　要：在我国北方严寒地区,农宅年供热能耗占户年总能耗的60%以上.通过对东北三省200户农宅供热能耗调研数据进行方差分析,筛选出均值差异显著、与北方农宅供热能耗关联强度大的影响因素作为评价指标.基于层次分析法,以北方农宅年供热能耗为目标层,以用户基本信息、建筑围护结构热工情况、供热通风系统、供热室内环境和居民用热行为5大类别为指标层,下分21个指标构成分项指标层,运用Matlab编程计算各层次权重系数,建立北方农宅供热能耗评价体系,并给出农宅供热能耗等级评价结果,为北方农宅供热节能改造及室内热环境的改善提供理论依据.In severe cold areas in northern China,the annual heating energy consumption of rural buildings accounts for more than 60% of the total annual household energy consumption.Through the variance analysis of the heating energy consumption data of 200 rural buildings in the three northeastern provinces,the influencing factors with a significant difference in mean value and large correlation intensity with the heating energy consumption of northern rural houses were selected as evaluation indicators.Based on AHP,taking the annual heating energy consumption of the northern rural buildings as the target layer,the user's basic information,the thermal conditions of the building envelope,the heating and ventilation system,the indoor heating environment and the residential thermal behavior were taken as the index layers,and another 21 indicators constituted the sub-index layer.Matlab programming was used to calculate the weight coefficients at all levels to establish a heating energy consumption evaluation system for northern rural buildings.Then,the evaluation results of the heating energy consumption of rural buildings was given,providing a theoretical basis for the renovation of the heating energy saving and the improvement of the indoor thermal environment of rural buildings.
