夏热冬冷地区热桥对建筑能耗影响的定量分析

热桥对建筑能耗的影响是相当大的,在夏热冬冷地区热桥是否需要做保温至今仍是一个值得探讨的话题,该文抛开热桥对结露的影响,通过对夏热冬冷地区具有代表性的三个城市不同建筑形态的实例工程进行模拟定量研究,分析了热桥面积百分比的变化对建筑能耗的影响及热桥部位有无保温层对建筑能耗的影响,表明在夏热冬冷地区建筑节能设计中,需要考虑热桥部位的保温措施。

Quantitative Analysis on the Effect of Thermal Bridges on Energy Consumption of Residential Buildings in Hot Summer and Cold Winter Region

Though there is a great impact of thermal bridge in a building on its energy consumption,whether the building in hot summer and cold winter region needs an insulation against the thermal bridge is still in discussion.Through quantitative simulation study of the projects with different architectural forms in three representative cities from the hot summer and cold winter regions,the effect of the percentage of thermal bridge area and of the existence or not of insulation layer at the location of thermal bridge on the building energy consumption is analyzed.It shows that the energy conservation measures should be considered in building design for the thermal bridge location of the building in hot summer and cold winter regions.
