Abstract: Recently, condensation and mold problems in apartment buildings have been on the rise due to increased insulation and airtightness performance for energy savings. Occupants in residential buildings have suffered property damage due to condensation and mold problems on built-in furniture, especially in Korean apartment buildings. Generally, condensation and mold growth on built-in furniture were found during summer and winter on the back panels of the furniture and adjacent surfaces of the exterior walls. Therefore, the aim of this paper is to analyze the characteristics of thermal environment and condensation problems in the adjacent area around built-in furniture through hygrothermal analysis simulations. We compared the surface temperature and relative humidity in condensation vulnerable areas and evaluated the condensation risk under winter weather conditions in terms of the amount of clothes, the type of insulation material, and the installation of a vapor retarder.
