Abstract
The amount of construction wastes are estimated to increase steeply in the first half of the 21st century in Japan as a result of intensive urbanization during the last century. Alternative policies for management and renewal system to urban structures considering lacking landfill sites and increasing scarcity of natural resources are planned and their environmental effects are estimated by applying LCA methods. In this paper, an approach from the viewpoint of product chain management is applied for urban structures. First, alternative management policies of urban structures, such as building design for recycling, facility management, and material recycling for building wastes, are designed extending the concept of product chain management. Secondly, estimation process of different future building locational patterns is prepared. Finally, the environmental improvement effects are estimated for different management scenarios in the national scale.
