Abstract

In Austria a lot of buildings suffer from rising damp and weathering, so that a high moisture content exists in the construction. Frequently problems start after the reconstruction, because new airtight windows are built-in and the high moisture content in the walls induces mould growth and other unhealthy and uncomfortable states. Investigations are done to simulate the behaviour of rooms in buildings with moisture problems to calculate the indoor climate. By the usage of prediction tools for construction behaviour and indoor climate it is possible to evaluate methods like mechanical air change with and without heat recovery, additional heating or different surface finishes. A ventilation device with humidity regulation and heat recovery
