In recent years, there has been a tendency to focus on high airtightness and the thermal insulation performance of houses for the purpose of the improvement of the indoor heat environment and reduction in the heating and cooling loads. However, the high airtightness and insulation performance increase the risk of intrusion into the inside of the wall, which causes interstitial condensation because the water vapor generated in the room cannot be discharged to the outside. In this study, we evaluate the anti-condensation performance of the walls using cellulose-fiber-based heat insulation (CF), which has a large moisture capacity and excellent moisture adsorption and desorption performance. The usefulness of CF is confirmed by clarifying the occurrence of internal condensation through measurement data analysis of a demonstration house, as well as numerical simulations.
