We made clear that water absorption and thermal conductivity of roof tile have a strong relationship between the fineness and components of clay, burning temperature and accuracy of molding through the mock-up experiments and test-piece analysis. And the traditional tiled roof of the Nakamura House, which is the oldest house in Okinawa and one of important cultural assets, has various vent devices based on the combination of regional materials in Okinawa. This porous roof is the determinant of cool and confortable environment in the house without the air conditioner.
