Glass and aluminium are commonly used materials
in modern buildings. At the Auckland Business School, however, these materials were taken to a new level. A distinctive facade was created using stainless steel spandrels, projecting striped glass sunscreens, aluminium aerofoil sunscreens, conical glass walls and exposed structural steel sunscreen fingers.
This work was contracted to window and curtainwall experts Thermosash Commercial. Managing director David Hayes says that within two years of being awarded the contract, the company was able to design, manufacture and install over 100 tonnes of structural steel for sunscreen trusses and the three-dimensional main entry, as well as designing, manufacturing and installing over 12,000m² of facade elements.
"The 12,000m² facade comprises some 2500 interlocking weatherproof aluminium, stainless steel and glass panels, in 767 configurations. Meeting the sequencing requirements of the main contractor's programme required honed logistical skills," says Hayes.
Similarly, 182 different configurations of sunscreens were structurally glazed at Thermosash and delivered on time to meet the requirements of the assembly and installation sequence for the curtainwall.
"These glass sunscreens are suspended from the curtainwall via slender brackets and aerofoil transoms, to which the screens are structurally siliconed. The design and coating used for these sunscreens is a world first."
