Abstract
The aim of this study is to make clear the environmental performance of the developed wall construction which is installed the insulation material on the exterior side of the mud wall. Filed measurement for hygrothemal environment in the test house was carried out. The test house consists of two rooms i.e. furnished with a mud wall and vinyl wallpaper. This paper describes the measurement result of indoor temperature and humidity for two years. Though the differences for daily mean temperature for two years between the mud wall and vinyl wallpaper was small, the differences for daily mean relative humidity was about 5-10％RH. According to measurement results in summer and winter, a peak and range of fluctuation for temperature and humidity were different in both room. Heat storage and moisture buffering effect of the mud wall with the insulation method were discussed. For future works, this measured data will be used for verification of numerical simulation. An optimization for the design as thickness of the mud wall and insulation etc. will be conducted.
