都市更新における環境負荷に関する研究

抄録

In this study, we developed the method of applying LCA approach to the downtown areas of large cities. This method enables comparisons of environmental load between the case of natural renewal, in which the urban structures is merely left as is, and the case of planned renewal, in which various approaches are used to give directionality and consistency for a project. For the analysis, we selected four quantities as indices for the environmental aspects - material usage, energy consumption, carbon dioxide emissions, and solid waste discharge. Utilizing this method, we tried to analyze the life cycle environmental aspects of the western district of Nakanoshima in downtown Osaka. Through this analysis, we found that the load relating of building accounts for a large proportion of the total emission in the district covered by our analysis.
