In the previous reports, a simplified transient method for determining the moisture diffusion coefficient of wall material was described, and measuring errors of the moisture diffusion coefficient obtained by the method were examined by simulation. In this paper, the experimental results using this method are discussed. The experiments are performed for air specific humidity step excitation and temperature step excitation, and applied to several building materials. The response of moisture gain is measured and moisture diffusion coefficients are obtained from the responses by using the transient methods. Experimental results are compared with the analytical results based on the moisture diffusion coefficients obtained from the experiments. The comparison shows good agreement between them. Morever, a complicated estimation method is examined and a comparison shows better agreement than with the simplified method. It is concluded that the simplified method are applicable to relative conductive building materials, but that complicated estimation method is more accurate.
