The Glaser method is an assessment procedure for the risk of moisture accumulation in building mono-dimensional structures, that could be used to evaluate mould risk and interstitial con- densation risk. It is based on a simplified model that does not represent the real phenomenon and its limitations are well-known qualitatively. This work provides a comparison in terms of moisture con- tent between the Glaser method and WUFI Pro, an advanced heat, air and moisture transfer prediction tool. First the influence of material properties is evaluated on four fictitious materials walls, then six different building envelope typologies for six weather files from Central and Southern Europe are modelled to evaluate the Glaser method results. The effects of the Glaser method simplifications are quantified in terms of moisture content percentage difference.

Abstract
The Glaser method is an assessment procedure for the risk of moisture accumulation in building mono-dimensional structures, that could be used to evaluate mould risk and interstitial con- densation risk. It is based on a simplified model that does not represent the real phenomenon and its limitations are well-known qualitatively. This work provides a comparison in terms of moisture con- tent between the Glaser method and WUFI Pro, an advanced heat, air and moisture transfer prediction tool. First the influence of material properties is evaluated on four fictitious materials walls, then six different building envelope typologies for six weather files from Central and Southern Europe are modelled to evaluate the Glaser method results. The effects of the Glaser method simplifications are quantified in terms of moisture content percentage difference.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
