This study focused on the humidity-control performance of the wooden dwelling spaces, which is related to the habitability. To evaluate the moisture-absorption performance in a condition close to real life, the room temperature and relative humidity were measured in a room using naturally processed sugi (Cryptomeria japonica) wood boards (Room A) and a room using chemically processed wood materials (Room B) as interior materials while subjects were asleep. The interior materials of Room A were free from chemical processing and those of Room B were comprised of bonded or coated woods. The results obtained from this study during 2014 and 2015 demonstrated that the Room A showed higher moisture-absorption performance than the Room B.
