| Outline of Final Research Achievements |
In this study, in order to clarify wood degradation process in actual building environment, wood decay tests under nonsterile conditions and validation of a prediction model were performed. The wood decay tests using rain water for infection with decay fungi showed that dispersion for decay rate occurred by contamination such as mold fungi. However the results indicated a possibility that maximum decay rates of wood in nonsterile conditions are equivalent to those of wood samples inoculated with pure-cultured decaying fungus under the sterile condition. Additionally the prediction model using measured hygrothermal conditions could approximately simulate the maximum decay rates. It was confirmed that the prediction model can be adapted to durability assessment for building envelope in actual construction site.
