Euro-Glaser unter Beachtung solarer Strahlungs-/ Absorptionsbedingungen sowie druckinduzierter Feuchteeinträge im Vergleich zu dynamischen Simulationen

Bernd Nusser, Thomas Bednar, Martin Teibinger

Abstract: In this report, the need to consider the convective moisture transport and the solar radiation and absorption conditions for the steady state evaluation of building components according to Euro-Glaser (EN 13788) [1] are shown. Therefor a flow rate equation for calculating the air exfiltration in building components is presented. Afterwards the heat and moisture flow equations of the Euro-Glaser-Method are extended with leakage air flow and the solar absorption coefficient and shadowing factor of the outer surface. The results of this calculations for flat roofs are compared with the results of transient 2-D simulations.
