Outside 構構 creation

摘要

PROBLEM TO BE SOLVED: To provide a building material and an outdoor facility structure which can efficiently exert a cooling effect on external air to be introduced into an inside of a building, enable a cool spot giving a sensory temperature lower than a surrounding environment to be created, and are applicable to a detached house with limited space.SOLUTION: A building material 1 comprises: a base material 2; an adhesion layer 3 which is installed on the base material 2 and has a hydrophobic property; and a porous material layer 4 with porous materials having a water-absorbing property compactly arranged on a surface of the adhesion layer 3. A photocatalytic material 8 which has a hydrophilic property is applied to the surface of the porous material layer 4. An outdoor facility structure is constructed by the building material 1.
