INDOOR AIR POLLUTION BY FUNGUS OF HIGHLY INSULATED HOUSES - BIOLOGICAL ASPECTS -

摘要

Since the energy-crisis of the 70'ies, the trend goes to energy-saving constructions, which have strongly changed our way of building. The development of highly insulated houses in combination with manual window-airing leads to problems concerning a good quality of the indoor air. Thus, mechanical ventilation-systems are built increasingly in detached family houses. In contrast to air-conditioning-systems there is no moisturising and cooling of the air. It can be assumed that there won't be any problems with microbial contamination. However, the long-time-experiences and measurements, that safeguard this assumption, are missing. The influence of the ventilation-type - mechanically or manually - on the existence of micro-organisms in the indoor air was regarded in the research-project [10].Additionally it was checked, how the formation of mould on heat-bridges depends on the surface-material and on the indoor climate, which on the other hand is influenced by the type of ventilation.
