Influence of internal and external boundary conditions on the decrement factor and time lag heat flux of building walls in steady periodic regime

摘要

The dynamic behaviour of opaque components of the building envelope in steady periodic regime is investigated using parameters defined by the fluctuating heat flux that is transferred in the wall. The use of the heat flux allows for the joint action of the loadings that characterise both the outdoor environment and the indoor air-conditioned environment to be taken into account.
