<p><P>PROBLEM TO BE SOLVED: To provide a building facing material and a building, capable of preventing or relaxing a heat island phenomenon in summer by effectively reflecting solar heat, and reversely absorbing and storing the solar heat as much as possible in winter. <P>SOLUTION: The building facing material 1 includes a number of horizontal triangular projections 3 disposed continuously in a vertical direction to form a sawtooth-shaped irregular surface on the outer wall of the building, so that the solar light can be reflected to the space by upward inclined surfaces 3x to the air. Each of the horizontal triangular projections 3 has the upward inclined surface 3x to the air side and a downward inclined surface 3y to the ground surface side, the angleθbetween the upward inclined surface 3x and the downward inclined surface 3y is set to about 75-90°, and the upward inclined surface 3x side has a gradient of about 45°relative to a horizontal plane 4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
