摘　　要：在德国和许多其他国家,建筑垃圾约占垃圾总量的一半。其实这种情况完全可以避免,因为现代建筑的可能使用寿命通常远远超过其实际使用寿命。拆除建筑很少是因为材料的耐久性不足,更有可能是经济性贬值或建筑类型过时所致。由于气候危机和资源短缺,我们在供应建筑材料和构件时需要从线性模式转换为循环模式。在现代,对旧建筑材料的再利用提倡尊重,不仅要尊重材料和能源的投入,还要尊重那些十分宝贵、不能被丢弃和降级回收的建筑构件在设计和制造时所付出的成本和心血。Construction is responsible for around half the waste generated in Germany and in many other countries.This does not have to be so:the possible service life of modern buildings normally far exceeds their actual service life.Lack of material durability is seldom the reason for demolishing a building.The more likely cause is economic obsolcscence or an outmoded building typology.The climate crisis and shortages of resources require a shift from linear towards circular material and component flows.The spolia of our times call for respect,not only for the material and energy input,but also the cost and effort involved in the design and manufacture of building components that are too valuable to be abandoned to downcycling.
