1 Scope This standard specifies the equations to be used in a simulation method for calculating the non steady transfer of heat and moisture through building structures. It also provides a benchmark example intended to be used for validating a simulation method claiming conformity with this standard, together with the allowed tolerances. The equations in this standard take account of the following storage and one-dimensional transport phenomena:
• heat storage in dry building materials and absorbed water;
• heat transport by moisture-dependent thermal conduction;
• latent heat transfer by vapour diffusion;
• moisture storage by vapour sorption and capillary forces;
• moisture transport by vapour diffusion;
• moisture transport by liquid transport (surface diffusion and capillary flow).
The equations described in this standard account for the following climatic variables:
• internal and external temperature;
