Towards data centre sustainability
Interxion is committed to designing and operating sustainable data centres by continuously optimising energy efficiency, reducing CO2 emissions and waste. The company is constantly refining its approach and developing new initiatives to move its facilities and its customers a step closer to sustainability.
In 2000 Interxion pioneered modular architecture for data centres and has since improved its PUE (Power Usage Effectiveness) year-on-year through a mix of design, procurement and operational measures, including the use of CFD (Computational Fluid Dynamics), free cooling and VFDs (Variable Frequency Drives) and custom-designed cold and hot aisle containment solutions to support high power densities more efficiently. To minimise energy waste, alternative cooling sources such as sea and deep water cooling are deployed wherever practical, and Interxion is in the process of implementing closed loop energy recycling systems where the heat generated in the data centre is recycled for use elsewhere. Emissions have also been significantly reduced by obtaining the majority of the power used in our data centres from renewable energy sources.
Modular Design
Interxion pioneered the modular approach to data centre design, and has been refining it since 2000. Modular architecture allows Interxion to match installed infrastructure capacity vs. IT load, which leads to lower start-up Power Usage Effectiveness (PUE).
PUE Performance
Interxion has calculated and enhanced its Power Usage Effectiveness (PUE) year-on-year since 2003, resulting in exceptional levels of efficiency. Details per facility are available to customers on a confidential basis.
Renewable Energy
Over 50% of the power provided to customers by Interxion is from renewable sources. Find out more about Renewable Energy.
Closed Loop Energy Recycling
Interxion uses closed loop design to recycle waste heat for other purposes.
Natural Cooling
Natural cooling features such as sea water cooling have been installed in facilities wherever practical since 2009.
Free Cooling
Free cooling has been installed as standard in all Interxion new builds since 2006.
Cold Aisle Containment
Cold Aisle Containment pioneered in 2004 and mandatory since 2008. This is a custom solution with self-closing mechanical doors and automatic self-venting roof panels which enables our facilities to support high load IT cabinets on low raised floors more efficiently.
Hot Aisle Containment
To optimise energy use for high-density IT loads, Interxion isolates hot air and feeds this to air conditioners creating a highly efficient closed system.
Variable Frequency Drives
High-efficiency Variable Frequency Drives are deployed in chillers, pumps and fans in Interxion's Heating Ventilation and Air-Conditioning (HVAC) systems.
Computational Fluid Dynamics
Interxion uses the latest Computational Fluid Dynamics software to maximise facility efficiency while supporting customer power and cooling needs.
Smart Lighting
Low-energy long-life compact fluorescent lights with motion detection are used in facilities and offices to minimise power consumption.
Best Practice Advice
All Interxion customers are provided with energy-efficient installation, monitoring and server management advice.
Smart Lighting
In order to provide our customers with increased choice, over 50% of the power provided for customers by Interxion is from solar, wind or hydro-generated energy.
