Teraco and Stulz win energy efficiency award


Teraco in collaboration with Stulz won an Award at the DCD 2017 Awards. The companies were commended for increasing energy efficiency and reducing the carbon footprint in a very challenging climate at the Isando Data Centre 7 in Johannesburg.

Now in their eleventh year, the DCD Awards went global for the first time and celebrated the best projects, technologies, companies, individuals and teams from across the industry. The 2017 event took place this month at London’s Royal Lancaster Hotel.  Approximately 700 guests gathered to celebrate these hotly contested awards which received over 200 entries from 30 countries.

Barrister turned comedian and broadcaster Clive Anderson, who hosted the event presented the Energy Efficiency Improvers Award (sponsored by Starline) to Brendan Dysel, Head of Infrastructure Management at Teraco, who commented: “The ambient conditions in South Africa provide great challenges to meet data centre efficiencies deemed the norm in global circles. The Stulz partnership with Teraco proved most successful and the DCD award for Energy Efficiency Improvers Award speaks volumes. The benchmark has been set and the engineering teams will now continue to improve on our current designs and sustainable operations.”

There was stiff competition from DigiPlex (Norway), Liberty Global in the UK and vXchnge in USA.   Teraco is the first provider of resilient, vendor neutral data environments in South Africa and is leading the way in the region by making energy efficiency one of its highest priorities.

The 27,500m2 colocation facility has a net cooling capacity of 2 MW, supplied by a chilled water system which is concurrently maintainable, with three CyberCool 2 chillers (N+1) and 14 CyberAir 3 chilled water units from Stulz. Due to extremely hot summers, the ambient temperature reaches 40°C. However, with water temperatures of 22°C/14°C Teraco is able to switchover into mix-mode at 20°C ambient temperature (approx. 5.700 h/a) to increase the energy efficiency by reducing the electrical power consumption of the chiller.  The design of the installation allows the use of free cooling for approximately 65% of the year, saving a significant amount of energy (circa 45%) and reducing Teraco’s carbon footprint.

Stulz also supplied the cooling solutions for The MareNostrum Data Centre in Spain which won the World’s Most Beautiful Data Centre Award.
