In Johannesburg’s Sandton business area, a new office building has been constructed. Comprising seven floors of office space, the Capital Hill development is worth over £10 million.
Designed by MWLF Architects, the building offers residential accommodation, as well as business facilities. It has been constructed to achieve a ‘Four Green Star’ rating from South Africa’s Green Building Council.
The building boasts green credentials and a carefully constructed design. Its architects were keen to create a ventilation that would not obstruct the smooth lines of its external facade.
Capital Hill’s elliptical central tower, which stands at 12 storeys tall, incorporates a glazed external facade within an aluminium lattice structure.
It includes an automatic window and vent opening system to provide natural ventilation and overnight cooling; smoke ventilation is also provided in the event of a fire.
SE Controls’ 49 SECO N 24 25 twin chain actuators were supplied to control the system, along with 7 SHEVTEC® control panels and manual control points (MCP).
The technology was networked using the company’s OSLink network cards and an external weather station was fitted to stream information on ambient conditions into the system.
The windows have been programmed to open and close automatically to introduce fresh air into the building, during normal operation.
In the event of a fire, however, the vents are opened to allow for the ventilation of smoke. This ensures that escape routes are kept smoke free.
