長寿命化トレンドを考慮した建物残存率のシミュレーション:建物の長寿命化トレンドにおける建材のストック／排出量の算出手法に関する研究 その１

Residual ratio of buildings greatly influences the estimation of building stock and amount of wastes from building demolition. However, it may depend on not only the age of buildings but also the age in which buildings exist. Especially, social background in Japan is drastically changing and building stock became more important than ever so that lifetime of buildings seem to be extended. This study discusses an estimation method of residual ratio of buildings under the trends in longer life of buildings as follows,<br>1. The simulation in which the residual ratio of buildings changes corresponding to both the age of buildings and the age in which buildings exist.<br>2. Verification of residual ratio of buildings by comparing between new residential construction statistics and housing stock statistics from 1961 to 1990.
