| Abstract |
Global warming and abnormal climate problems have recently become serious, and the need to reduce carbon emissions has emerged. For
effective carbon emission reduction in the building sector, research on carbon emission reduction from the perspective of the entire life cycle,
including both operational carbon and embodied carbon, is required. Among them, the demand for modular apartments is expected to increase
as the quantity and size of orders have recently increased, and large-scale public projects have been scheduled. Therefore, this study set up
30-year and 60-year use scenarios for apartments and analyzed the carbon emission reduction effect of modular apartments compared to
reinforced concrete apartments throughout the life cycle. The amount of embodied carbon in the material production stage of modular
apartments was reduced by 35.1% compared to reinforced concrete apartments. In the case of carbon emissions throughout the life cycle, the
30-year scenario will be reduced by 15.4% and the 60-year scenario will be reduced by 18.5% |
