PROBLEM TO BE SOLVED: To control temperature fluctuation caused by sunlight in a veranda or an outside corridor.SOLUTION: A guide part 4 is mounted to a ceiling surface 3b of an external space (e.g., veranda or outside corridor) of a building 3, and a louver B is supported to the guide part 4 in a freely movable and invertible manner. Then, a panel member of which light reflectance is different between one side and the other side is used for a louver board of the louver B. Therefore, temperature fluctuation caused by sunlight can be controlled in accordance with whether the side of higher light reflectance is directed to an outer side A of the building 3 or to an inner side (side indicated by a code 3a). |
