Building with System
Over a century of construction experience in complex infrastructure
Industrial prefabrication know-how for modular constructions
Understanding what a structure must deliver over its lifecycle
Where computing power meets responsibility
YEXIO is the physical foundation of a sovereign cloud in Europe. Made of wood, powered by green electricity, and where you are.

Who builds YEXIO
An architect rethinks the data center
Behind YEXIO stands HOCHTIEF Data Center Partner - a spin-off of HOCHTIEF PPP Solutions. A company that has been building infrastructure that lasts for generations: airports, tunnels, skyscrapers. With YEXIO, HOCHTIEF transfers this understanding of durable, responsible construction to the most important infrastructure of the 21st century - the data center.
Climate-friendly IT infrastructure
Lifecycle thinking instead of throwaway architecture
Data centers as energy hubs for their surroundings
Location, architecture and technology as one system
Born from PPP DNA
Emerging from HOCHTIEF PPP Solutions
Public-private partnership experience with municipalities and authorities
Sister spin-offs: Solarpartner, Ladepartner, EDGITAL

YEXIO breaks with the idea of the data center as an anonymous gray box. Six principles underpin the concept - and show why YEXIO is not "just another data center".
Lifecycle thinking - planning, construction, operation, and decommissioning as one connected system
Energy hub function - the data center interacts with the city and region instead of burdening them
Local integration - location, architecture, and technology are tailored to people and the environment on site
Modular and prefabricated - faster construction time, less material waste, more precise quality
Edge instead of hyperscale - computing power close to the data, not far away
Distributed instead of centralized - a network of sovereign locations instead of one mega-campus
The idea
Six principles, a new standard

From energy to cloud: integrated infrastructure across the entire lifecycle
Every infrastructure decision affects efficiency, sustainability, and scalability. Therefore, YEXIO considers the entire lifecycle of digital infrastructure — from construction and energy integration to cloud operations and regional use.
