Mechanical Technology: April 2011
The recently occupied Absa Towers West building in Troye Street Johannesburg is the latest addition to the Absa Campus, which now comprises nine buildings spread across Commissioner and Anderson and Von Wielligh and Mooi Streets in central Johannesburg. Absa Towers West is not only built to be one of the most eco-friendly and energy-efficient buildings in South Africa, but as a result of the power uncertainty created in 2007, the entire campus is also self-sufficient. An energy centre capable of generating the maximum demand for the entire campus – 11,2 MW from gas powered engines and 6,0 MW of emergency backup from diesel units – has been installed in the car park of the new building. Peter Middleton takes a tour of the facility.
