INVESTIGATION OF ACTUAL HUMIDITY CONDITIONS IN HOUSES AND EVALUATION OF INDOOR ENVIRONMENT BY FUNGAL INDEX

The characteristics of climate in Japan are hot and humid in summer, with cold and dry winter. For thisreason, mold growing in rooms is common during summer period. On the other hand, in winter, due tospace heating, indoor environment is over-dry as a result of low humidity.

MEASURED FUNGAL INDEX DETERMINED USING FUNGAL GROWTH AND COMPUTED FUNGAL INDEX BASED ON TEMPERATURE AND RELATIVE HUMIDITY IN HOUSES

The fungal index is a biological climate-parameter, which represents the environmental capacity toallow fungal growth. The author developed software that determines the computed fungal index,which was estimated using the Excel software "INDEX" from the measured temperature and relativehumidity. The computed fungal index and the measured fungal index, determined using a fungaldetector encapsulating fungal spores, were determined in 10 rooms in six dwelling houses.
