Abstract

Recently, the condensation and mold problems of apartment buildings has been growing due to high insulation and high air-tightness performance for energy saving. Most of all, occupants in residential buildings has suffered from property damages due to the condensation and mold of built-in furniture. Condensation at built-in furniture were generally found in winter at the of furniture's back panels, adjacent surfaces of wall, floor and ceiling. These problems are related to the weather conditions and indoor room conditions in winter. To understand these condensation problems, it is necessary to investigate the thermal environment around the built-in furniture and living spaces in winter. The aim of paper is to analyze the characteristics of adjacent area around built-in furniture's condensation problem and the thermal environment around the built-in furniture in winter through the field measurements at apartment buildings. In this research, the thermal conditions around the built-in furniture were measured during winter season. In results, it is important to consider increasing surface temperature for higher $16^{\circ}C$ and decreasing absolute humidity due to the occupants' behavior around built-in furniture for preventing condensation.
