摘　　要：采用Flixo软件对内置保温系统层间结构受力挑板热桥部位进行模拟研究得出挑板外侧无保温、挑板外侧米贴不同保温材料及上下延伸不同尺寸、挑板厚度不同等构造做法下的线性热桥值和内表面温度,及其变化规律;采用DeST软件针对被动式超低能耗建筑能效指标模拟得到能耗计算时较合适的外墙传热系数限值,进而反推得到内置保温系统用于严寒寒冷地区被动式超低能耗建筑中的可行性方案。Flixo software is used to simulate the thermal bridge part of the interlayer structurein the built-in thermal insulation system,and the linear thermal bridge value and internal surfacetemperature are obtained under different construction methods,such as no insulation on the outside ofthe cantilever plate,different insulation materials pasted on the outside of the cantilever plate,up anddown extension size and thickness of the cantilever plate,and the thickness of cantilever plate.Inthis paper,DeST software is used to simulate the energy criteria of passive ultra-low energy buildingsand obtain the appropriate limit value of external wall heat transfer coefficient in energy consumptioncalculation,and then the feasibility scheme of the application of built-in thermal insulation system inpassive ultra-low energy buildings in severe cold and cold zones is deduced.
