摘　　要：对三元食品工业园节能建筑的保温技术方案进行了设计,包括建筑墙体、外窗、屋顶保温技术。通过对工业园科研楼的围护结构热工参数及冷风渗透量等热工性能进行测试表明,外墙平均传热系数为0.493 W/(m2·K),内部设置吊顶的屋面传热系数为0.314 W/(m2·K),外窗传热系数为2.7 W/(m2·K),冷风渗透次数为0.43次/h。应用DeST-h软件对建筑能耗进行模拟,与北京市建筑标准规定的参考建筑的能耗对比分析,得出该建筑的实际节能率达68.6%。通过建筑保温技术方案的实施,工业园的节能建筑每年可节能约合258 tce。Building insulation technologies applied in Sanyuan Food Industry Park were designed, including wall, window and roof insulation technologies. Thermal performance test showed that the average thermal transmittance of external wall is 0.493 W/（m2·K）, the thermal transmittance of proof with inside ceiling is 0.314 W/（m2·K） and that of the external window is 2.7 W/（m2·K）. The number of infiltration is 0.43/h. Energy consumption was also simulated using DeST-h. Results showed that the energy saving rate of the demonstration building reaches 68.6%. Through conducting building insulation, the energy saving buildings in Sanyuan Food Industry Park can save about 258 tons of standard coal per year.
