自1974年爆发世界性石油危机以来,节约能源问题就引起全人类的关注。建筑能耗数额庞大,在整个社会能耗中占有举足轻重的地位,不容忽视。建筑节能涉及的范围很广,包括建材工业节能、结构节能、照明节能,能源控制、太阳能的利用等方面,本文仅就建筑围护结构的节能材料报道国外的新进展,供有关方面参考。一、各国对建筑节能高度重视国外对建筑节能工作十分重视。苏联在1978—1979年期间,发布了一系列指令性文件,旨在提高建筑物的热保护。按照1979年发布新的建筑热工技术,对建筑物围护结构热阻的要 Since the outbreak of the world oil crisis in 1974, the issue of energy conservation has attracted the attention of all mankind. The huge amount of building energy consumption occupies a decisive position in the entire social energy consumption and cannot be ignored. The scope of energy conservation in buildings covers a wide range, including energy saving in building materials industry, energy saving in structures, energy saving in lighting, energy control, utilization of solar energy, etc. This article only reports on new developments in energy conservation materials for building envelopes for reference by relevant parties. First, countries attach great importance to building energy conservation attach great importance to building energy conservation work abroad. During the period from 1978 to 1979, the Soviet Union issued a series of directive documents aimed at improving the thermal protection of buildings. According to the new building thermal engineering technology released in 1979, the thermal resistance of the building envelope structure
