Built for compute: why purpose-built beats retrofit for AI

Empty modern industrial hall being prepared for data center fit-out

A surprising number of data centers were never meant to be data centers. They began as warehouses, offices, or industrial buildings and were fitted out for compute later. That works up to a point. For dense AI and high performance workloads, the difference between a building adapted for compute and one designed for it from […]

Air or liquid: cooling choices for dense AI compute

Cooling is where a lot of data center design quietly happens. For years air was enough for almost everything. Then AI workloads pushed hardware density up sharply, and the old assumption stopped holding. The result is a real choice between air and liquid cooling, and the right answer depends on what you are running. Why […]

What happens to the heat: waste heat reuse in a Nordic data center

Every data center turns electricity into computation, and almost all of that electricity leaves again as heat. The interesting question is what happens to the heat next. In most of the world it is simply released into the air. In the Nordics there is a more useful answer, and it is shaping how we are […]

Why Finland for compute
