Unsteady coupled air, moisture and heat energy flow through a porous solid is simulated numerically using a boundary element model (BEM). The governing transport equations are written and solved for the continuous driving potentials, i.e. relative humidity, temperature and air pressure. The moisture redistribution inside a wall with capillary active interior insulation is analysed to illustrate the applicability and accuracy of the proposed numerical model.
