ESTIMATION OF THE WOODEN BUILDING STOCKS AND PROPOSAL OF ITS MANAGEMENT IN TOKYO

Abstract

 The buildings and social capital constructed for the rapid economic growth period are accumulated as enormous stock in Tokyo. It is predicted in future that these will be abandoned as deterioration stocks because of their life-ends all at once. In this study, we set the scenario which considered influence by the demand falling with the population declines and the long usage of the wooden buildings, analyzed their stock, and estimated a quantity of the vacant houses which will not be maintained as deterioration stock in Tokyo. As the result, we suggest proposals of the stock management by the related-constituent, which are followings : the recycling ticket of buildings' version, the selection of the reusable materials and construction method when they build them, the use of existing stocks with the control of newly-built, the scheme of the buildings' time-serise records, and the establishment of the emergency, like the disasters, waste-treatment fund.
