Estimation of mould growth levels on rendered facades based on surface RH and surface temperature measurements

Författare

Summary, in English

Many façades made with thin rendering on thermal insulation have problems with biological growth. In this study surface temperature and surface RH were monitored over a 20 month period on test house façades with different constructions (thermal inertia), surface color and compass directions. This data were used to test three theoretical indices of biological growth with the aim of indicating the potential of mould growth on different types of rendered façades. The result show that thin renderings on thermal insulation have significantly higher surface humidities compared to façade constructions with higher thermal inertia and therefore have a higher potential for mould growth. The color is the most important factor for the surface humidity levels on south facing façades (on the northern hemisphere) as darker surfaces absorb more solar radiation and therefore have a higher average temperature. On a north facing façade the heat storage capability of the façade and its effect on the surface temperature is most import
