建築の資源循環性に関する環境影響評価手法の研究

抄録

This study examines an environmental impact assessment method (LCA assessment method) from the view point of resource recycling nature in buildings. A LCA Assessment Method is proposed based upon the newly examined structure of the LCA assessment and the LCA database. The structure is composed of three components such as the composition and quantity of building machineries and materials, the repair and renewal, the LCA assessment items. The first one is composed of 7 items such as the machineries and materials, the quantity per unit and so on. The second one is composed of 2 items such as the repair rate and renewal cycle. The third one is composed of 15 items such as the quantity of recycling material consumption, the by-product quantity of building construction and demolition consumption, the level recycling percentage of material and so on. The LCA database is composed of 11 items such as the design specification, the machineries and materials and so on. By setting a conventional housing model and a resource recycling oriented housing model, resource recycling nature is evaluated using the LCA Assessment Method.
