Interesting but uncomfortable light displays in library [447]

The main façade of the building is characterised by the first layer of filters, a fixed metal mesh that doesn't allow to see the interior from the exterior.
As second layer we find a filter of vertical pivoting textile louvers, which can form some differents atmospheres in the reading room of the library.
Between them we find an intermediate space, a kind of balcony inside the metal mesh façade.
