被动式超低能耗建筑外围护结构隔热保温方法研究

分析了建筑能量需求边界与建筑能源使用边界是确定被动式超低能耗建筑能量体系的2种边界,在此基础上,通过被动式超低能耗建筑能量体系分析被动式超低能耗建筑具有高保温、高气密性、热回收新风系统、高保温性门窗以及无热桥设计5个特征,基于被动式超低能耗建筑特征从高性能隔热保温材料、无热桥设计、高气密性、被动式门窗、防水隔汽系统、遮阳设计6个方面研究被动式超低能耗建筑外围护结构的隔热保温方法,被动式超低能耗建筑将成为未来节能减排的重要方式。

Research on thermal insulation method of passive ultra-low energy building exterior protection structure

It is analyzed that the boundary of building energy demand and the boundary of building energy use are two kinds of boundaries to determine the passive ultra-low energy consumption building energy system. On this basis,through the passive ultra-low energy consumption building energy system,it is analyzed that the passive ultra-low energy consumption building has five characteristics:high insulation,high air tightness,heat recovery fresh air system,high insulation doors and windows,and no heat bridge design. The characteristics of the passive ultra-low energy consumption building are studied from six aspects :high performance thermal insulation materials,non thermal bridge design,high air tightness,passive doors and windows,water and steam insulation system,and sun shading design. The passive ultra-low energy consumption building will become an important way of energy conservation and emission reduction in the future.
