Recently, the condensation of walls in domestic high-rise apartment buildings is an important problem. The exterior climate factors through the analysis of the Seoul climate data are analyzed and the change of indoor temperature by using Apache program to find the cause of the condensation state and prevent condensation is predicated. Also, according to this result, exterior climate factors and interior factors, which caused the condensation, were examined. The thermal performance of the curtain wall and the range of potential condensation were analyzed to focus on high-rise apartment buildings through computer simulation programs. The main purpose of this study is to develop the algorithm for the surface condensation prevention on curtain wall in high-rise apartment buildings.
