The influence on indoor thermal environment under the sod covered roof was studied. The roof was covered by the soil with a thickness of 100mm and turf grass. Continuation observation of air-temperature, globe-temperature, humidity and wind-speed has done in the room of the third floor (attic room), and the room of the first floor in the mid summer season of 2003 and 2004. The results evaluated using Fanger's PMV index shows that there is no big difference in the thermal environment of the third floor and the first floor. Since the surface of an attic cools the interior of a room effectively, indoor thermal environment of the third floor was kept comfortable. When the simulation of the difference from an ordinary roof (rock-wool slate roofing) was carried out, it turns out that the load of indoor air-conditioning becomes about 1/21.
