The transformation of old concrete buildings has become the social focus with the redevelopment of Chinese cities. The object of this study is reuse value of old concrete building; the purpose establishes the valuation system of old concrete building.According to the theory of sustainable development and the theory of life cycle energy consumption in the paper, it has performed value study to reuse value on the old concrete building through dual angle theoretical analysis and case studies. A more perfect evaluation system is initial established for reuse on the old concrete building with group eigenvalue method,expert grading and matter element theory in the paper. This system consists of three models: structure reliability evaluation model, recycle value assessment model and value of scheme optimization model. Valuation results show that the system is feasible and practical with the system to a certain industrial building."Energetic" concept is introduced in the paper, the building life cycle energy consumption theory is improved by the combination of the building consumption and "Energetic". Economic analysis of civil engineering is injected into new blood introducing fuzzy matter element analysis to it. Comparing with previous comprehensive assessment of the building which focuses on cultural value and economic value, this paper also regards ecological value as one of the key factors. It has certain significance.The research results of this thesis have reference and guidance to the modification of old concrete buildings. |
