| Abstract |
This study calculated the depreciation for the transfer and re-installation of modular units in residential facilities and proposed a formula to
determine the recycling rate based on the number of years passed. The analysis showed a recycling rate of 32.5% after 50 years. These
findings can serve as a basis for increasing the recycling rate of modular units in the future, and suggest that business plans should consider
recycling timelines of 20-25 and 40-45 years for residential facilities. However, this study only accounted for full repairs when calculating
depreciation, without considering the large and medium-scale repairs typically applied to RC buildings. Future research should expand to
include not only full repair depreciation “0” but also partial repairs over the entire analysis period. |
