摘要
在寒冷地区传统砖混结构的建筑中，窗的传热能耗约占总能耗的 20％，而在节能建筑中，约占 30～ 40％。因此，窗的保温优劣，将直接关系到建筑节能 50％的目标能否真正实现的大问题。在实验、研究的基础上，文中提出了窗的多层化、加窗帘、加强气密性、采用节能换气装置、采用中空玻璃等是窗的保温节能的有效措施，并定量地给出了采用不同方法所能获得的节能效果。
In cold district, the energy lost by conduction of windows in traditional brick buildings assumes about 20 percent of total energy consumption, while 30％～ 40％ in energy saving buildings. Therefore, whether the heat preservation of windows is good or bad has much to do with the complete realization of saving 50 percent of energy used in buildings. Proposed that adopting multi layer window, window curtain, sealed insulating glass, air exchange unit of energy saving and improving air tightness are the effective means of thermal insulation and energy saving of window on the base of experiments and research. The energy saving effects of these different methods were presented.
