Omfang

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;- internal and external humidity;- solar and longwave radiation;- precipitation (normal and driving rain);- wind speed and direction.The hygrothermal equations described in this standard shall not be applied in cases where:- convection takes place through holes and cracks;- two-dimensional effects play an important part (e.g. rising damp, conditions around thermal bridges, effect of gravitational forces);• hydraulic, osmotic, electrophoretic forces are present;daily mean temperatures in the component exceed 50 °C.
