A technique for the prediction of the conditions leading to mould growth in buildings

In-cavity evaporation allowance—A drying capacity indicator for wood-frame wall system

“…Moisture level in wood material is usually expressed by two related parameters: moisture content (MC) of the material, such as reported in [18,19,21], or the ambient relative humidity (RH), such as in [9,30,34]. RH is more popularly used in modeling of surface molds, while MC is frequently used in testing, for example, to establish the moisture limit for wood-based components in the building envelope.…”

Evaluation of the influence of hygric properties of wallpapers on mould growth rates using hygrothermal simulation

“…He has also divided building construction materials into four classes according to the type of substrate with respect to the nourishment that the material is able to provide for the fungi. Clarke et al [8] have also proposed the limit curves of mould growth. In this approach, the principal mould species affecting the U.K. dwellings were identified and their minimum growth requirements, in terms of temperature and relative humidity, were established.…”

Influence of concrete fracture on the rain infiltration and thermal performance of building facades

“…15(a)), illustrates moisture accumulation in the component. Both phenomena are known to accelerate degradation mechanisms: the amplitude of drying/wetting cycles accelerates the chemically induced degradation suffered by concrete [3] (alkali-silica reaction, steel reinforcement corrosion, carbonation) and accumulated water may cause frost damage in case of low temperatures, or diffuse towards the entire envelope and generate mould growth [7]. In regards to both these parameters (moisture accumulation and wetting/drying cycles), it is clear that the presence of cracks inevitably accelerates degradation processes.…”
