A comparison of different mould prediction models

To predict the mould growth risk during the design stage, a mould prediction model can be used. Several models are found in literature (e.g. temperature ratio, isopleth systems, biohygrothermal model, ESP-r mould prediction model, empirical VTT-model). Each of these models includes however different assumptions. Consequently, a different conclusion may be drawn depending on the used prediction model. In the current paper, a comparison between the different mould prediction models is made. To do so, the hygrothermal behaviour of two thermal bridges is simulated and the obtained surface temperature and surface relative humidity are used as an input in the different mould prediction models.
