Interactive calculation of coupled heat and moisture transport equalising by computer e.g. for construction of buildings - involves developing equations for thermal storage capacity and moisture storage capacity of building material.

Abstract
The method iteratively computes coupled heat- and moisture (vapour) transport equations based on the heat-storage capacity of the damp building material, the moisture-storage capacity of the building material, the heat-conduction capacity of the damp building material, the liquid coefft. of the building material, the water-vapour permeability of the building material, the vaporisation enthalpy of water, water-vapour saturation pressure, the temp. and relative humidity. In the case of insufficient convergence after ni-iteration steps, if the max. change in the relative humidity during two successive iteration steps increases only once, average factors are automatically introduced into the interaction process.
