Key points
  • “Compared with a traditional datacentre built with steel and concrete, we lower the embodied carbon of the full structure by three times.” With a complex the size of a football pitch, that is a lot of wood, but, says Wernvik, “the amount of timber one of our datacentres uses takes the Swedish forest about 10 to 15 minutes to grow back”.
  • Huge panels of cross-laminated timber arrived at the site pre-cut, and were assembled by crane according to instructions, like flatpack furniture.
  • Aesthetically, this section of the datacentre is more like an Ikea before the fit-out, a cavernous, echoey, immaculately clean hangar.

One difference is immediately visible: this datacentre is made out of wood.

The wood is not EcoDataCenter’s only claim to sustainability; it is more than just cosmetic, says Wernvik, the company’s chief external relations and sustainability officer.

Additional details
  • It is built of wood, resembles an Ikea and its power is totally renewable.
  • It looked like a very large Ikea,” says John Wernvik, of EcoDataCenter.
