摘　　要：以陕西关中典型乡村建筑的实地调研资料为基础,采用正交试验法对乡村自保温建筑能耗影响因素进行多元组合分析,通过极差分析确定了影响乡村自保温建筑能耗因素的主次关系及最优方案。结合多元因素组合最优方案,以典型乡村居民的实际需求为依据对乡村自保温建筑进行了空间再设计,并对典型自保温建筑的节能响应进行了分析研究。研究结果表明,多元因素组合时影响乡村自保温建筑能耗因素的主次关系为:屋顶传热系数>外窗传热系数>建筑朝向>挑檐长度>窗墙比。由此可知,在进行乡村自保温建筑节能设计时,应重点加强外围护结构的保温性能。运用DesignBuilder软件分别对基准建筑模型和典型自保温建筑模型进行能耗模拟,通过计算可知,相较于基准建筑典型自保温建筑的单位面积能耗的节能响应为63.3%。Based on the field research data of typical rural buildings in Guanzhong,Shaanxi province,this paper confirmed the optimal multi-combination of energy consumption for rural self-insulation building by orthogonal experiment method and the priority of multi factors by range analysis,according to the actual demand of typical rural residents,re-design the space of rural self-insulation building combining the optimal combination,analyze the energy efficiency response of typical rural self-insulation building.The results show that the priority of multi factors was roof heat transfer coefficient,window heat transfer coefficient,building orientation,cornice length and glazing ratio,indicated that it should enhance the insulation of external building envelope in rural building energy-efficiency designs.The DesignBuilder software is applied to simulate the energy consumption both of benchmark building and typical self-insulation building,the conclusion show that the energy eficiency response rate was 63.3%of typical self-insulation building compared with benchmark building,which rate was energy consumption per unit area.
