Refurbishment of BMW South Africa’s head office in Midrand – a landmark building beside the N1 highway between Johannesburg and Pretoria – began in 2013 with occupation taking place the following year in June 2014.
Works included completely stripping the inner façade to increase visual connections, efficiency of the circulation space and transmission of natural light via a fully-glazed façade. This included a sustainable transformation of the lighting, ventilation solutions as well as maintaining optimum temperature (thermal comfort) and energy efficiency throughout the entire building with the installation of a satellite Energy Centre and PV installation (i.e. solar panels) – all monitored by an online, visual metering system.
The building was awarded a 5-star As-Built rating by the Green Building Council of South Africa (GBCSA) in 2014 making BMW South Africa the first automotive company in South Africa to receive the rating.
The GBCSA rating system took into consideration the indoor environment quality, energy, transport, water, materials, land use and ecology, emissions as well as innovations.
The variables that contributed to BMW South Africa’s GBCSA 5-star rating included:
- Glass and solar controlled louvres installed within the internal façade of the building, enabling enhanced daylight and thermal comfort,
