| Abstract: | Iterative application of two simulation tools to enable the determination of the required airing to preclude mould growth in corners. A newly developed whole building model is able to determine the effect of different ventilation schemes on indoor climate. Feeding the resulting surface temperatures and humidities to a biohygrothermal model allows to assess the risk of mould growth. For given ambient conditions it is thus possible to determine the necessary minimum ventilation rate by iteratively applying the two models. As an example, different building constructions are investigated, showing the effect of different natural ventilation schemes (continuous ventilation versus pulse ventilation by opening the window) on the minimum mean air change rate required for preventing mould growth. |
