요약2 The purpose of this study is to derive the formula which indicates influences of density, specific heat and porosity upon the calculation of the cumulative condensation amount per year inside the wall under abnormal conditions, among permeability performance of the inner-insulation wall. For this, the followings are conducted: (i) A one-dimensional wall shape composed of concrete structures, insulation materials and interior materials is established; (ii) Reflecting factors considering the spread caused by the difference in indoor and outdoor vapor pressures, i.e. thickness, thermal conductivity, and vapor resistance coefficient, the cumulative condensation amount per year, i.e. the characteristic value of the three-way factorial design method per level of each factor; 'Result 1' (iii) The maximum cumulative condensation amount per year is calculated per each level according to EN 15026 by adding the density, the specific heat and the porosity, which are factors for humid performance; and based on the foregoing, 'Result 2' (iv) the correlation with regard to the influences on the density, the specific heat, and the porosity of each material layer is derived. Through this process, the relation between the vapor diffusion performance and the humid performance is defined. The study results are as follows. (i) The pattern of comparison between the 'Result 1' and 'Result 2' is similar. (ii) The difference in density, specific heat, and porosity state quantities is not considered to be a factor affecting the diffusion of water vapor due to the difference in the partial pressure of vapor and capillary phenomenon. (iii) The increase of density, specific heat and porosity does not seem to have a proportional effect on the amount of condensation.
