At Datacloud Global Congress 2026, Capacity’s Amber Jackson speaks with Bertrand Rotagnon, Executive Director for Data Centres in Europe at Carrier, about how rapid market expansion, AI-driven density and regional shifts across Europe are reshaping data centre design. As operators push beyond traditional hubs into markets such as the Nordics and Southern Europe, Rotagnon explores how cooling is evolving from a technical requirement into a strategic investment priority. From modular deployment and faster commissioning to renewable energy integration and heat reuse, he outlines how thermal infrastructure is becoming central to the next phase of data centre growth.
