ABSTRACT
In buildings growing conditions for mould fungi can occur and cause fungus infestation. The danger for the occupants of dwellings lies in the production and spreading of pathogens (disease causing agents). Therefore, consequent measures have to be taken to avoid health dangers that come from mould fungi in buildings. In order to avoid the mould fungus formation, a strategy has to be set up that focuses on the growth conditions for mould fungi. The most important boundary conditions for the growth of fungi are temperature, humidity and substrate conditions which have to be simultaneously available over a certain period of time. A new biohygrothermal procedure is developed, which allows the prediction of mould growth under transient boundary conditions. This new method is described and its application is demonstrated on different practical examples.
