Every room in the school has wide lattices that allow natural diffused light to come in from both sides of the room. This is achieved by the innovative use of "light shelves" which act as both sunshades and also light reflectors sending natural light deep into the rooms. Concrete "grilles" provide an attractive screen for safety and protection as the children move along the well-ventilated corridors. Wall-to-wall windows on opposite sides of every classroom allow cross ventilation, helping to circulate copious amounts of air in the room and cool down the temperatures during summer.
