[Problem] to drastically reduce energy consumption by reducing the heat load from solar radiated heat during summer and efficiently absorbing solar radiated heat during winter, while suppressing the reduction in light volume inside a room. [Solution] A curtain wall structure is provided wherein: a plurality of louver units (1, 1...) are arranged at prescribed intervals in a horizontal direction on the outside of a curtain wall panel (CWP); each louver unit (1) has two sheets of glass (5, 6) arranged inside a frame, with an air layer (7) disposed therebetween; two porous panels (8, 9) with a plurality of holes are arranged inside the air layer (7) at intervals and parallel to the two sheets of glass (5, 6); the surface of each porous panel (8, 9) on one sheet of glass (5) side is colored a whitish color and the surface on the other sheet of glass (6) side is colored blackish; air communication ports (2b, 3b) that communicate between the air layer and the louver unit exterior are each disposed on the top and bottom end of the surface on the one sheet of glass (5) side, and the curtain wall structure is supported rotatably around a rotating axis core in the vertical direction. |
