Microperforations in 22@ 
This facade is designed to protect the building from the South, South-east where the solar incidence is much higher. The closure is a glass facade, allowing in light and illuminating the reception of the building, the stairwell and the vast majority of work-study classrooms. The microperforated plate regulates the entrance of light.This facade uses a metal framed structure to hold the glass. On each floor we find a half-meter small footbridge that facilitates the cleaning of the facade.
