The invention concerns an efficient device for exploiting the natural varying elements of wind, heat and light inside a building by means of a movable roof surmounted by glass panes inclined at 60 DEG . It consists of a fixed structure 1 on which pneumatic rollers 2 are arranged, some of them being controlled 3 by an electric motor 4 in order to turn a tubular structure 10 equipped with opaque 30 DEG faces 11 and glazed 60 DEG faces 12 of fixed panes 13 and of movable panes 14. This structure 10 is placed on a girderage 8 connected to the raceway 9 and to the pivot 7. Pivot 7 which retransmits the forces to the fixed pivot pin 5 by way of a ball bearing 6. <IMAGE>
