| Research Abstract |
Hygrothermal materials, interior wall components with humidity controlling properties, are increasingly being used for building construction in Japan. Although there are reports on the performance of these items, little information is available on potential contamination caused by microbial growth on hygrothermal materials. In this study, we conducted field measurements in environment by using hygrothermal materials, and examined the growth characteristics of mould present on the surface of hygrothermal material under conditions of moisture exposure. Due to the field measurement results, it is clear that hygrothermal materials made multiplication of mould promote. Furthermore, experimental studies confirm the utility of using the proposed MGI to evaluate mould growth under defined conditions on different substrates.
