The implementation of all buildings on the site created a shaded area between the northern hill & the main building. This becomes a source of fresh air flowing towards the soccer ground through this 160 m long building providing natural ventilation to all classrooms: a micro-climate is created with different wind cycles. The wind caught by the aerodynamic roof shape expels the overheated stagnant air radiated from between the two roof layers inspired by the centuries old traditional Okinawa house with it’s tiled roof separated from the inner ceiling and it's natural ventilation through the foundations eliminating also the humidity raising from below. Solar angles on southern concrete facade panels provide comfortable natural lighting at all seasons thus reducing considerably the need for artificial lighting.
