Northern France hosts green data centers

14 Dec 2015 | A region on the move, IT

By the year 2020, data centers could consume as much as 10% of global energy output. Over the past several years, hosting companies in Northern France have developed alternative centers—just one example of the region’s commitment to next-generation energies and the digital revolution.

OVH: Keeping it cool

OVH is the number 1 internet hosting company in Europe and number 3 worldwide, and since 2003 the Roubaix-based company has been working to make its data centers more energy-efficient.

Since 2010, for example, all new OVH centers have followed a simple equation: 30% air cooling + 70% water cooling = 0% air conditioning. Air and water cooling combine to create an innovative new system, eliminating air conditioning completely.

CIV: Green alternative

In Lille and Valenciennes, CiV’s Alternative Datacenters by CIV offer a completely independent solution for hosting eco-friendly next-generation servers, using high-performance technology and pooled hosting to cut environmental impact in half. Naturally cool air is injected into the system, lowering indoor temperatures and providing over 260 days of free cooling annually. In winter, the system warms the building by capturing heat generated by the IT equipment.

Décima: Geothermal energy

Décima’s data center in Arras, located in a converted powder magazine in the city’s historic citadel, is the first commercial building north of Paris to be ISO 50001-certified for energy management. Thanks to its geothermal technology, the facility consumes two to three times less energy than conventional data centers.

Cold water is pumped from 35 meters below ground to cool the servers and then returns—slightly warmed but not polluted—to the ground water. The Arras data center also features the latest smart-grid technology, allowing Décima to track and manage all of the energy consumed by the building.
