The Building Design Methods Study Based DfD Theory

The theory of DfD (design for deconstruction) considers architecture development from the point of the whole lifetime of building. As we all know, the global is facing the serious environment problem. The voice of improving sustainable development is higher and higher in our society. And the notion of the sustainable development is present at every respect of our lives. We must encourage sustainable building in the architecture field. So our thinking should extend from building constructing to building dismantling. We have to treat the influence of building on the environment at a further view. The researching for Design for Deconstruction is important for our natural resources, the energy policy, and the development of our society. The developed countries have achieve some success in this field right now.The first chapter explains the DfD (design for deconstruction) conception, background, the development worldwide, and the methods of study.Chapter2describes the obstacle to develop Design for Deconstruction from building designing, building dismantling, and the using of "old" building materials and components the three respects.Chapter3tells the development of the Theory of Building Layer and the Theory of Recycling Hierarchy. This two theories support the DfD.Chapter4gives some ways in buildings designing and dismantling according to the DfD theory. This part of article studies some abroad successful cases.The last chapter summarizes the meaning of the researching of DfD for Chinese development, and suggests the new requirements for the development in the building field.
