确定一个国家建筑物的寿命分布对于估计其存量/流量至关重要。这项工作是第一次使用建筑存量和流入量的最新数据来确定1964年至2020年日本所有木制和非木制建筑的寿命功能和半衰期。木结构建筑的对数正态分布被证明是最合适的寿命函数,1964年的半衰期为38年,1965年至1996年为56年,1997年至2020年为63年。相反,对数正态分布(类似指数分布)最适合非木制建筑物,其半衰期在1964年为22年,1965年至1990年为33年,1991年至2020年为52年。重要的是,未来的研究使用这些寿命函数来探索未来的预测建筑存量/流量,并实施措施,以有效地减轻环境影响,如气候变化。
Ascertaining the lifetime distribution of a nation's buildings is critical for estimating their stock/flow. This work is the first study to use the latest data on building stocks and inflows to identify the lifetime function and half-life of all wooden and non-wooden buildings existing in Japan from 1964 to 2020. The log-normal distribution of wooden buildings proved to be the most suitable lifetime function, with a half-life of 38 years in 1964, 56 years between 1965 and 1996, and 63 years between 1997 and 2020. On the contrary, the log-normal distribution resembling exponential distribution was the most suitable for non-wooden buildings, with a half-life of 22 years in 1964, 33 years between 1965 and 1990, and 52 years between 1991 and 2020. It is important that future research uses these lifetime functions to explore future predictions of building stock/flow and implement measures to effectively mitigate environmental impacts such as climate change.
