Hetzner Online data center park granted TÜV seal of approval
TÜV SÜD experts have assessed the use of energy-efficient technologies at
Hetzner Online's data center park in Falkenstein/Vogtland and awarded a
certificate for 'Energy-efficient company - Data Center' as well as a
Power Usage Effectiveness (PUE) 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 specialists were particulary 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."
