So far the several studies have been carried out in viewpoint of the history and structural compositions of the Neolithic thatched-roof dugout hut(Um house) which has been used as the normal housing for about 1000 years in the Neolithic era, however the thermal characteristics analysis of the Um house has never been studied. In this study, the thermal environmental characteristics of the Um house in the Neolithic era was analysed experimentally. The results could be summarized as follows: .1. When the solar insolation and the ambient temperature in the daytime were 420W/m2 and 17℃ respectively, the surface temperature of the Um house roof covered with the rice straw was 37 ℃ and that in the roof 32℃, and in the conditions above the air temperature in the room was 15℃. 2. When the ambient relative humidity was 40%, that in the room of the Um house 50%, and at the ambient relative humidity of 90∼100%, that in the room was 60%. 3. In general the comfort degree in the living space is changed with the seasonal climate, also in this study, the comfort degree in the room of the Um house in October and November was higher than that in May and June.
