Abstract
Some building materials which are frequently used indoors were chosen to determine the speed and the range of temperature and relative humidity of atmosphere of fungal growth. The fungi tested were six groups which were collected in dwelling and identified. New "tatami" mat, plywood, plywood with surface coating with plastic material, plaster-board, hinoki, sugi matu and later "tatami" mat and straw-base were used to determine the possibility of growth at 25°C, 100 % RH. With tatami mat, new and old, and straw-base, the growth speeds were determined at both four temperature (5, 15, 25, 35°C) and at five kind of humidity conditions (100, 90, 85, 75, 66 %) were tested. With tatami straw-base all fungi showed significant growth at all conditions.
