Estimation of accumulation of construction material using identification of buildings in time-series in the Greater Tokyo

Abstract

Toward the sound material-cycle society, it is required to understand the detailed distribution of material stock in urban areas over a wide range in time-series. This research estimated the replacement of construction material and visualized spatial information in timeseries in the Greater Tokyo. Total floor area of renewal construction materials is 112 million m² (2003~2009), and 75.6 million m² (2009~2015) using identification of buildings in time-series. Moreover, total floor area of demolished construction materials is 54.2 million m² (2003~2009), and 46.4 million m²(2009~2015). The total floor area of renewal construction materials which estimated in this study was about 0.7-1.2 times and demolished construction materials was about 3 times compared to the Tokyo Metropolitan Statistical Annual Report.
