Abstract
Understanding quality and quantity of material stocks and urban metabolism, forecasting demolition waste are essential in order to establish a sound material-cycle society. The influence of socio-economic changes and geo-spatial characteristics to building lifespan are required for a detailed urban metabolism analysis. In this study, we construct an urban structure (Building, Road, Railway) database of the city center of Nagoya (approximately 12 km2) from 1949 to 2009, and we established a building lifespan model for urbam metabolism analysis considering socio-economic changes and geo-spatial characteristics parameter. As a result, we quantified the building lifespan by floor number, population density, building structure type and official discount rate. In adition, we compare and examine between the actual demolished builing data from 2003 to 2009 in Nagoya city center and result of the simulated demolished building using building lifespan model. Simulated demolished building was 4.85 Mtonnes in the actual demolished building which is 6.03 Mtonnes. Demolition judgement using building lifespan model can estimate for high rise building such as RC building.
