加气混凝土单一保温节能墙体体系的再议论 顾同曾北京建筑设计研究院摘 要不同气候区使用加气混凝土制品作为单一墙体材料节能体系，运用不同密度和厚度的产品可以满足当前我国各个气候区规范对外墙的热工性能要求几种典型的外保温复合墙体，在采用近似墙厚和热工性能的前提下，无论社会效益和经济效益，单一墙体节能体系优势明显配套构件及有关产品标准、大力推广应用节能体系的条件已经成熟在严寒地区，特别是A区的应用虽有优势，但不能简单地仅靠增加墙厚来解决所有问题，还应补充其它措施。 关键词A Re-discussion on Aerated Concrete-based Single Insulation and Energy Efficiency Wall System GU Tong-zeng (Beijing Institute of Architecture Design, Beijing 100045, China) [Abstract] In this paper, aerated concrete single insulation and energy efficiency wall system was demonstrated in the aspects of utility in different climate areas, economy and technology. It was concluded that as single insulation and energy efficiency wall system, aerated concrete with different densities and thicknesses could meet demands of thermal performance regulations in each climate area. Compared with typical heat preservation complex walls, the energy-saving effect of this system had obvious advantages, no matter for social and economic benefits, provided with almost same wall thickness and thermal performance. In consideration of production techniques, supporting components and relative products standards, it was time to promote this energy efficiency system. Meanwhile, this system had disadvantages in cold area, although its application in A area had advantages, the problem could not be solved by increasing the wall thickness only, other measures would also be needed.
