The authors verified the simultaneous heat and moisture transfer model using six different full-scale test walls in which hygroscopic materials were used. Humidity, water content and temperature inside the walls were measured for about one year in the field test. Principal physical properties of used materials were measured independently in other experiment rooms. One-dimensional numerical calculations corresponding to the test were performed by applying the measured physical properties and the observed boundary conditions. Agreement between the calculation and the measurement is fairly good except for materials composed of cement, such as aerated concrete. Validity and subjects on the model were suggested.
