the economic use of materials on large external surfaces . Glazing was reduced to a minimum to ensure maximum natural light and ventilation .
Roofing is as flat as possible with around a 7 ° pitch which minimises the massing of a large roof . Roofs are also interspersed with angled roof lights which include ventilation , natural light and smoke extraction .
Steel roofs are further linked to steel cladding façades , reflecting an industrial appearance and side cladding is also fixed with flutes in horizontal form to further reduce the vertical appearance .
The colour combinations of the façade are firstly dictated by the in-situ grey concrete colour and are then contrasted with red brick and dark grey steel cladding – all in attempt to place the structure and infill panels in an ordered pattern . These materials are locally sourced : red brick , concrete , stone and sand from local quarries and glass and aluminium are all sourced from local suppliers and manufacturers .
Sustainable Design A passive design approach was used when taking sustainability into consideration . To maintain a comfortable temperature range internally , the need for auxiliary heating or cooling was reduced . Less than 35 % of the project is mechanically ventilated and all is compliant with SANS 10400 . A Building Management System ( BMS ) controls power and HVAC usage to the campus , preventing any wastage or excess usage by the users .
