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

The methodology developed was used to evaluate the influence of external and internal loadings on the dynamic characteristics of two commonly used walls on a monthly and seasonal basis. The external loadings were changed considering two climatically different locations and different orientations of the walls; the internal loadings were changed by varying the operating mode of the plant and the shortwave radiative heat fluxes contributions on the inner surface.
