Architect and Builder June/July 2018 | Page 26

MATERIALS The project had used approximately 21,691m³ of concrete, 9,260m² of double glazed panels, and 2,868m² of Sandstone cladding which compliments the three primary materials in bringing this building into being. HVAC & PLUMBING The services were divided into two zones. Emergency services in basement level 2 and the building services on the roof. All HVAC plants were installed on the roof with water reticulation running up the building to the roof and then down. Due to its gravitational nature drainage was established in the service ducts behind the toilet cores. Vertical reticulation of 26 HVAC Ducts and chiller pipes were also positioned around the same core areas feeding fan-coil units in the ceiling voids of the Werksmans office spaces. SUSTAINABLE ELEMENTS The design has taken all the SANS10400, Part X and XA into consideration,. The lighting design was done with as low as possible W/m² and water saving measures was implemented through astute engineering acumen. A glass box design in any terms presents a challenge concerning the thermal behavior of the building, but the team managed to successfully resolve this through the selection of the type of glazing and the specific blind preferences to control glare and heat gain through the façades. 96 Rivonia Road
