Glass Triple glazed

Cladding  7,300 sq m of triple glazed low emissivity coated clear glass, incorporating shading devices

 Low-e coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted.

 External shading devices incorporated in the building facade to limit the internal heat gain resulting from solar radiation. Most commonly these take the form of horizontal sunshades attached above windows on south facing walls.

Vertical louvres also are effective for east and west facing windows.

Steel  Steelwork: Structural frame - 2100 tons Reinforced - 1950 tons reinforced steel and concrete  Rebar (short for reinforcing bar) is a common steel bar or mesh of steel wires commonly used as a tension device in reinforced concrete and reinforced masonry structures, to strengthen and hold the concrete in compression. The surface of the rebar

may be patterned to form a better bond with the concrete. It is also known as reinforcing steel and reinforcement steel.
