Energy-saving automatic window obtained by using solar energy during the cold season, control of solar radiation in summer, thermal insulation, controlled internal incidence of light, controlled air exchange

An energy saving window system comprising:

• a frame extending along the perimeter of a window;
• two movable window panes disposed on opposite sides of the frame to define a volume enclosed between the window panes and the frame;
• an outer window casement coupled to one of the two window panes;
• an inner window casement coupled to another of the two window panes, the inner window casement comprising a plurality of mating parts, a first mating part of the plurality of mating parts being affixed to the frame and a second mating part of the plurality of mating parts being movable from the first mating part;
• an actuation system disposed within the volume, the actuation system comprising one or more independent drive shafts connected to one or more drive motors;
• a plurality of action levers disposed in the volume, said plurality of action levers comprising a first group of action levers being situated in the upper part of the volume and a second group of action levers being situated in the lower part of the volume, said first group and said second group being symmetrical along a vertical axis, each action lever having a first end and a second end, each action lever in the first group being coupled at the first end to the first end of an action lever in the second group, each second end being coupled to the outer or inner casement so that the actuation system causes the action levers to rotate and the window panes to move one in relation to the other;
• and
• a plurality of multiple hinges each coupling one of the outer or inner window casements to the frame, the plurality of hinges being extendable and supporting the window panes when the window panes move one in relation to the other.
