The structure is constructed out of reinforced concrete.
The wall sections above shows wind suction cups supported by horizontal wind suction cables that transfer the wind forces to the frame . The frame and the suction skin are connected by hinged supports directly connected to the floor slabs. There are also woodwool slabs and metal gratings on the interirior walls that help reduce the reverberation time so there is still silence in the atrium regardless of the havoc occurring.
The roof consists of steel trusses that span up to 37 m at the widest point, and are constructed of tubular beams. The roof has mostly glazed areas to allow lighting into the whole building, stop direct sunlight into the office spaces, and natural lighting into the atrium.
The roof assembly shown below consists of a double glazed post and rail structure with rain gutters and drain pipes. The insulation consists of a vapour barrier aluminum sheet.
Green Building: Filters out heat and exchanges heat.
