Due to East and West facing glazing covering an extensive amount of the envelope, louvres have been used to reduce direct sunlight and natural heating. These louvers cover both East and West facades of the volumes but not of the intruded circulation and crossing cores. The louvers cover both glazed and non glazed areas. To achieve maximum shielding on glazed areas the louvres move by a maximum of 45 degrees from the buildings trajectory in both directions. Each volumes louvres move independently of each other as the angle facing towards the south differs each other. Louvres used for a consistent aesthetic feel to the exterior do not move.
