<p><P>PROBLEM TO BE SOLVED: To make effective use of sunlight energy while reducing an amount of solar radiation received by a perimeter zone of a window glass of an opening it an exterior wall part. <P>SOLUTION: A concavity 3 is formed in the exterior wall part 1 by recessing a lower part of the window glass 2 provided in the exterior wall part 1 toward the room interior side so that its outer surface can face obliquely downward. Then a solar battery panel 4 is mounted below the window glass 2 in the concavity 3 in a slanting attitude so as to face obliquely upward to the side away from the exterior wall part 1. Furthermore, the window glass 2 is made Low-E glass. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
