近年来,用化学合成材料为主的现代建材建筑的住宅,已从各方面暴露出对人体健康的危害,因而引起了人们对住宅发展史的反思。在西德,被人们誉为“仙厦”的生态住宅,已在各城乡涌现。这种住宅完全不用钢筋混凝土、塑料、石棉以及化学涂料等现代建材,而全部选用木材、树皮、毛竹、泥土、石灰等天然材料,并对这些材料进行反复的检验 In recent years, the use of chemical synthetic materials in the modern building materials of residential buildings, has exposed all aspects of the harm to human health, which has led to people’s reflection on the history of residential development. In West Germany, ecological houses that have been hailed as “Xianxia” have emerged in various urban and rural areas. This type of house does not use modern building materials such as reinforced concrete, plastics, asbestos, and chemical paints. It uses natural materials such as wood, bark, bamboo, soil, and lime, and tests these materials repeatedly.
