Interior-surface condensation on the glazed curtain wall of high-rise residential buildings is an important environmental issue in Korea. There are three causes of the surface condensation. One is the curtain wall frame materials, another is the generated moisture from residents' behaviors such as cooking and drying the laundry, the other is inadequate ventilation caused by stack effect. The purpose of this study is to analyze the hourly occurrence of interior-surface condensation on the glazed curtain wall for the comparison to design alternatives at the design stage of high-rise residential buildings by using numerical models. The results can be summarized as follows; The possibility of condensation occurrence in the upper floors is higher than that in the lower floorsdue to the stack effect.
