Mould contamination has negative consequences on the indoor air quality, and then on the health of the residents. It has an important significance for studying the mould contamination on building wall, especially in the south China. A dynamic mathematical model for simulating the coupled heat and moisture transfer within multilayer hygroscopic building wall was proposed. Temperature and humidity are critical for mould germinating. With the simulation results from the hydrothermal model, software WUFI-bio was used to evaluate the mould risk in the building. Once the humidity and temperature com...
