Datacentres are deeply unpopular. Has Sweden made one we can all love?

In short

The football-pitch-sized facility provides an 80-megawatt capacity while directing 70 percent of its computing power toward Nvidia-driven artificial intelligence workloads. It operates on a grid that is 75 percent hydroelectric and 25 percent wind, relying on hydrotreated vegetable oil rather than conventional fuels for backup generation. Furthermore, the volume of harvested timber utilized across the entire structure regrows naturally in Swedish forests in roughly 10 to 15 minutes.

‘It was pretty cool, when they were building it. It looked like a very large Ikea,” says John Wernvik, of EcoDataCenter. He is giving me a tour of their facility in Falun, Sweden, which could lay claim to being the world’s greenest datacentre – although to many, that is a contradiction in terms.

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