Abstract
This study considers to review the renewal characteristics of forty five hospitals which constructed with a theory of modern hospital planning, in 1970s. This investigation results can be concluded as following : (1) Five years after completion, the number of renewal project is still less. It gradually increases and reaches maximum in ten to fifteen years, at this period, the renewal project approximately for two years. (2) The frequency perhaps reduce gradually after fifteen years. At this period, the main focus of renewal project is reconstruction of building facilities, especially maintenance for utility, interior, and equipment. (3) It is common that a high-frequency renewal causes the bad condition in the hospital environment. Therefore, the fundamental problem is site maintenance for building and landscape environment.
