TÜV SÜD awards Hetzner Online certification for most energy-efficient data center park with the best energy-efficient result (PUE) ever calculated by TÜV SÜDFalkenstein, Germany, July 2011. TÜV SÜD experts have assessed the use of energy-efficient technologies at Hetzner Online's Falkenstein/Vogtland data center park and granted certification for "Energy-efficient company - Data Center" with a PUE (Power Usage Effectiveness) of 1.1242. "Hetzner Online has achieved the best PUE result ever recorded during certification by TÜV SÜD up to now", TÜV SÜD officials conclude. TÜV SÜD is an international service corporation focussing on consulting, testing, certification and training. It is present in over 600 locations worldwide and based in Munich, Germany.
TÜV SÜD specialists were particularly impressed by the effective use of free cooling and the use of highly-effective UPS (Uninterruptible Power Supply) systems. The systematic acquisition of energy data was also very positively evaluated including the monitoring of main consumers, as well as air volume control to consistently avoid unnecessary use of energy. No additional heat is used to provide warmth to data center buildings.
"The certified location attains on average remarkably high energy-efficiency annually, as shown in the PUE factor (Power Usage Effectiveness) of 1.1242," said Dr. Michael Bunk of TÜV SÜD.
This means that at the Falkenstein location only approximately 12 per cent of electrical energy drawn on average each year is used for ancillary processes, such as cooling, ventilation and lighting. More than 87 per cent of the electrical energy drawn goes directly into computing power for customer applications.
For Michael Horn, Head of Energy Management at Hetzner Online AG, the certification from TÜV SÜD is a very special award: "Energy-efficiency is a top priority for us from both an environmental as well as from an economic viewpoint. The PUE achieved is also a notable value on an international scale."
Power Usage Effectiveness is an efficiency metric comparing the power used by a data center' s infrastructure to its existing IT load. According to a survey of more than 500 data centers conducted by the Uptime Institute the average PUE rating for data centers is 1.8.
