The new building is simultaneously a connection and articulation point: it links the east and west buildings and articulates the levels of the south outdoor courtyard, the sports area and a covered outdoor area. The use of natural ventilation and protection of the northern openings was a must requirement. The architects then decided to create a permeable brick facade to allow air flow, illumination in the northern rooms and window protection, hiding the ventilation grids. To the south exterior shading slabs and interior screens were used in order to control the light intensity in the classrooms.
