Just chill: How Nordic data centers stay cool

Article published by W.Media on May 13

A recent feature in W.Media explores how Nordic data centers are setting new standards for sustainable cooling by leveraging natural climate advantages, renewable energy, and innovative heat management strategies.

The article highlights how operators across the Nordic region are reducing reliance on traditional mechanical cooling systems through approaches such as free-air cooling, seawater cooling, hybrid evaporative technologies, and heat recovery. These methods are helping data centers achieve exceptionally low Power Usage Effectiveness (PUE) while supporting the growing demand for AI and high-performance computing infrastructure.

atNorth is featured as an example of how Nordic operators are utilizing naturally cool climates to improve energy efficiency. The article references atNorth’s campuses in Iceland and Finland, where ambient temperatures support highly efficient cooling strategies, as well as the company’s planned 300MW mega site in Sollefteå, Sweden.

The feature also highlights the broader Nordic advantage, including access to renewable energy, strong connectivity, and a growing focus on circular economy initiatives such as heat reuse. As demand for digital infrastructure continues to accelerate, these factors are positioning the Nordics as a leading destination for sustainable, high-density data center development.
