Outline of Final Research Achievements

When remains of earthen cultural assets are displayed in an open exhibition, the enclosures are usually built to protect them from natural elements such as rain or solar radiation. However, these facilities often cause secondary deterioration, for instance, condensation on the enclosures, or damp ground around the remains, following a shower of rain.
The exhibition hall at the Heijyo-kyu palace site is the subject of this study. We itemized and classified the secondary deteriorations of the remains and then attempted to clarify the reasons for the deteriorations both qualitatively and quantitatively. Based on the results, we proposed a design method for the publicly accessible facilities to ensure the earthen cultural assets are effectively preserved.
