摘要：介绍了超低能耗建筑发展趋势和地产关注点，以地产的角度从技术和经济层面分析了阳台和女儿墙部位优化的必要性。以超低能耗建筑女儿墙和阳台部位典型设计为基准，采用COMSOL为工具量化了女儿墙不同优化方式导致的增量线性热桥，量化了不同结构板宽度阳台在端部保温取消后的增量线性热桥。结果表明，女儿墙可以通过减小整体或局部结构层厚度、调整女儿墙结构形式等方法控制线性热桥增量在较小范围内，以实现取消女儿墙保温压顶的设计；阳台端部取消保温层后增量线性热桥与阳台宽度有关。

Abstract：The development trend of ultra-low energy consumption buildings and the focus of production on products are briefly introduced. From the point of view of real estate， the necessity of optimizing balcony and parapet wall is analyzed from the technical and economic aspects. Based on the typical design of parapet wall and balcony of ultra-low energy consumption building，the incremental linear thermal bridge caused by different optimization methods of parapet wall was quantified by COMSOL，and the incremental linear thermal bridge of balcony with different width of structural plate was quantified after the end insulation was cancelled. The research shows that the increment of linear thermal bridge can be controlled in a small range by reducing the thickness of the whole or local structural layer and adjusting the structural form of the parapet wall so as to cancel the design of thermal insulation and roof-pressing of the parapet wall. Incremental linear thermal bridge at balcony is related to balcony width when the insulation layer of the end of balcony is removed.
