Outline of Final Research Achievements

In this study, a simulation model was developed based on the city of Nagoya and its surroundings. This model estimates a building’s demand and life cycle (from construction to demolition) by considering various future socioeconomic scenarios. We also incorporated the basic material units for construction and disposal (demolition) of buildings. Furthermore, the amount and life cycle of wood furniture and the area of trees and grass in the city were analyzed. Through these analyses, the quantity and quality of wood waste were understood, and it became possible to present methods for effective use of the wood waste. In particular, we clarified the relationship between the supply and demand of wood and the wood waste under different conditions of urban spatial structure such as a compact city and promoted wood houses and longer housing life span. As a result, it was possible to present methods for effective use of limited resources.
