PURPOSE:To give a remarkable effect on energy conservation in a building through the year, by a method wherein a reflective heat-absorbing glass window in rotatably provided, solar radiations are effectively excluded in summer, and the solar radiations are effectively taken into the interior in winter. CONSTITUTION:In a light-transmitting body 41 for a composite window, a surface of a light-transmitting flat plate capable of absorbing a portion of solar radiations is treated to be capable of reflecting a part of the solar radiations, and a frame 42 for supporting and fixing the body 41 is supported by a window frame member 44 so that the frame 42 can be rotated by at least 180 deg. relatively to the frame member 44. Accordingly, solar heat can be effectively utilized in each period of the year by directing the reflection-augmented surface of the light-transmitting body 41 to the exterior to reduce cooling load in summer or in intermediate periods of cooling, and directing the surface to the interior in winter or in intermediate periods of heating. |
