Situated at 320 Madiba Street, Tshwane House is a modern municipal centre that aims at bringing local government closer to the people. Constructed on the site of the old Munitoria building, the new City of Tshwane headquarters and council chamber set the tone for the spatial reconfiguration and rejuvenation of the inner city.
Designed by LYT Architecture, the building is placed on street level with easy access for pedestrians.
“Most importantly, it is the building’s integration into the social context and its social connection with the City of Tshwane that define its identity and sets it apart from other civic buildings in the city,” explains Warren Stanley, director at LYT Architecture.
“We aimed to create a defining structure for the chamber; a recognisable object that can be identified by the people of Tshwane as a symbol of the decisions that are made by their appointed representatives.” he states.
Government goes green
In line with the government’s commitment to green building, Tshwane House incorporates many sustainable features and has achieved a five-star Green Star SA – Office v1 Design rating.
A variable air volume (VAV) air-cooled system is connected to CO₂ monitors that ensure optimum fresh air is provided, at a rate of 12l/s/p. Paints, adhesives, sealants and carpets with low or no VOCs were specified. To assure further indoor comfort for the 1 590 city employees, 70% of the useable area has a direct view of the outdoors, with thermal comfort maintained in 95% of the useable space.
Efficient lighting and occupancy sensors are installed throughout the building and energy uses of 100kVA or greater, as well as all major water uses, are sub-metered and controlled via a building management system. Water from a rainwater harvesting and filtration system is used to flush the toilets and urinals, efficient water fittings were installed and greywater is harvested from showers for irrigation.
The chamber facade is clad with Rheinzink zinc alloy with glazing at the bottom to provide a sense of transparency. “Rheinzink is used often in urban buildings around the world, so it speaks to the civic nature of Tshwane House,” notes Stanley.
“In addition, it is a very hard-wearing and robust material that lasts a long time. Interestingly, the Rheinzink cladding will change its appearance over time, taking on its own character and patina as it ages with the building.”
