摘　　要：以寒冷地区农村典型砖混结构建筑为基准,对其各项节能措施进行优化和局部敏感性分析,采用全寿命周期费用法和净现值法对各项节能措施进行经济性评价和静态回收期计算。建筑节能设计敏感性大小依次为建筑气密性>外墙保温>屋面保温>外窗传热系数>外窗SHGC>地面保温。采用装配式建房节能模块外墙和屋面的最佳保温层厚度均为110 mm,外窗最佳传热系数为2.5 W/(m^(2)·K)。Based on typical rural brick-concrete structure buildings in cold rural areas,optimization of various energy-saving measures and local sensitivity analysis are carried out.The economic evaluation and static payback period calculation of various energy-saving measures are carried out using the life cycle cost method and net present value method.The sensitivity of building energy conservation design is in order of building air tightness>exterior wall insulation>roof insulation>heat transfer coefficient of exterior window>SHGC of exterior window>floor insulation.The optimal thickness of insulation layer for exterior wall and roof is 110 mm,and the optimal heat transfer coefficient for exterior window is 2.5 W/(m^(2)·K).
