Résumé

In the paper, a numerical model is employed for the calculation of the transient wall heat flux, under the effect of a step temperature change at a particular wall side, for given initial and boundary conditions. The results were employed for the evaluation of the wall thermal time constant, which is widely employed quantity in physics and technology to describe the transient output response characteristics of a system under the influence of a step change of a particular input variable parameter. Thermal time constants were evaluated for a number of typical walls, broadly employed in construction practice, and the results were comparably presented and discussed in respect to their fundamental significance on the load characteristics and energy demand of buildings.
