Equilibrium moisture contents(EMC) were calculated based on temperature and relative humidity of atmosphere and actual EMCs were measured at intervals of ten days in previous air-dried wood samples for seven different species including Douglas fir and oaks in four indoor locations in central region for one year. Mean annual air temperature and relative humidity were 23.3℃ and 54.9% in bedroom, 22.9℃ and 59.5% in living room of apartment. 20.1℃ and 57.0%, in office morn and 19.4 and 64.0% in living room of tile-roofed house, respectively. Mean annual calculated and actual EMCs were 10.2 and 9.7% in bedroom, 11.1 and 10.2% in living room of apartment, 10.7 and 10.4% in office room, and 12.1 and 12.5% in living room of tile-roofed, house, respectively. Actual EMC of kasai were higher than average value of EMC for seven species. However, those of sycamore and apitong were lower than average value.
