夏热冬冷地区建筑外墙节能探讨

Discussion on energy-efficient of exterior wall in hot summer and cold winter zone

针对夏热冬冷地区的气候特点,比较了常用节能墙材的热工性能,并利用国家墙体材料评价体系进行了评价,讨论了各种外墙保温隔热结构体系的优缺点和做法,指出外墙外保温具有内保温和中间保温不可比的技术优势,值得大力推广。

Aimed at climate characteristic of hot summer and cold winter zone, the paper compares thermal performance of energy-saving wallmaterial, and the wall materials are evaluated by wall material evaluation system from national science and technique department, discusses advantage and disadvantage of various types of energy-saving structures of exterior wall, point out that the external wall themal insulation has the technical disadvantages that the internal wall thermal insulation and the middle thermal in sulafion can not compared, and is valuable to promote.
