This project uses custom designed sunscreen to control natural light into the building. The monitors are shaped to eliminate direct light and to maximize the amount of indirect light. The monitors’ shapes are specific to this building in this location with this shape of roof (patent pending) . The sunscreen is made of cast aluminium and is manufactured in 4 feet by 4 feet units. 912 units cover the building’s roof and each unit weighs 150 lbs. La Societa Sider s.r.l. (Bologna, Italy) manufactured the units.
