This paper investigates the effect of ventilation on mould growth in a typical Japanese bathroom byuse of the fungal index which indicates the growth rate of a mould, Alternaria alternata S-78. Thebathroom was set in an artificial climate where the temperature and relative humidity (RH) werekept constant. The temperature, RH and fungal index in the bathroom were measured under severalventilation methods after taking a bath. The results showed that it is extremely effective to ventilatemechanically in order to decrease the mould growth rate and also useful to ventilate with circulationof heated air and exhaust (drying and exhaust) in order to dry the bathroom near the floor.Experimental data indicated that ventilation with drying and exhaust after taking a bath has a greatinfluence on the control of mould growth and has twice the control effect as with only exhaust.
