7.2.3 Openings in the north and south walls, the exposed side of the human height of the wind, and interior wall openings

Window height and details have been modified to be in two parts with different heights. Those of the north direction must be the same in height with the human being. Opposite ones must be in a higher position to enable the required crossventilation. This will give the occupants the controllability of opening the upper or the lower parts according to the weather condition.
