Lifetime Distribution of Buildings Decided by Economic Situation at Demolition: D-based Lifetime Distribution

By using the balance equation between input, output, and net addition to stock, we developed a method to estimate the lifetime distributions for buildings by statistics and some parameters from former studies.

Description
Summary:By using the balance equation between input, output, and net addition to stock, we developed a method to estimate the lifetime distributions for buildings by statistics and some parameters from former studies. Understandable lifetime distributions were obtained from 1987 to 2010 in the type of lifetime distributions for cohort demolished in each year (D-based lifetime distribution), which was based on a hypothesis that demolition would be decided by some reasons at the time of demolition. We found that time-series change of the average lifetime depends on the economic situation, at least in the country where replacement is the dominant method of construction.
