Abstract

Wooden architecture should be repaired when their durability deteriorates due to the effects of temperature and humidity. In the repair of wooden buildings, temporary construction are installed to protect members. In this process, the physical environment changes and may affect the microclimate of the site. However, related academic research is insignificant. This study is to investigate the climate and moisture content change patterns according to the changes in the physical environment of the site. Myeongjaegotaek is currently a suitable target for achieving the purpose of the study as a temporary construction is installed as a repair work. Therefore, the measurement data before and after the installation of the temporary construction were compared and analyzed through the microclimate measurement equipment. As a result, the inside relative humidity increased due to changes in the physical environment, such as the installation of temporary construction. This was also shown in the correlation analysis by location. The moisture content of wood was found to be as high as 20% or more when the average relative humidity inside the temporary construction was over 80%. Environments with high wood moisture content can have a negative impact on durability. As a result of correlation analysis, relative humidity showed a strong relationship with temperature and wind. Therefore, it was important to plan for natural and artificial air flow during the time when the temperature rises when the relative humidity inside the temporary construction is high. As such, this study confirmed that the method of analyzing the actual microclimate data was appropriate for deriving empirical results. In addition, it was found that monitoring using scientific techniques is advantageous for accumulating meaningful data on wooden architecture cultural assets.
