It is well known that fungi may scarcely germinate or grow in the house with sufficient ventilation. This effect may be a rule of thumb because scientific background such as experimental data or field test data are not shown. This study aims to clarify the ventilation effectiveness against prevention of fungal outbreaks in dwellings on the basis of full scale tests. A method of pair comparisons between a room with proper ventilation and a room without ventilation were adopted. In these rooms, building materials such as tatami mat. which is the Japanese traditional flooring, made of straw mat. plywood, wallpaper and so on were placed in order to observe germination or colony forming. Germination or colony forming on the building materials, set in the room with sufficient ventilation, were not confirmed although fingal contamination occurred in the room without ventilation. Measuring data of temperature and relative humidity in both rooms were compared with the thermal conditions preventing the growth of 4 kinds of hygrophile fungi, as was reported in the former paper. Measuring data in the room without ventilation were overlapped with the specified thermal region, nevertheless thermal condition in the room with proper ventilation was beyond the specified thermal region.
