Energy-saving contracting in the data center of the University of Stuttgart

ENGIE reduces remote cooling consumption by 75 % and increases data center operational reliability

The computer center of the University of Stuttgart (TIK) operates and supports digital information processing and communication technology at the University of Stuttgart. It plans, advises and coordinates the basic concepts for the information supply for both software and hardware equipment and organizes the media services of the university.

In the building Allmandring 30a - the canteen large kitchen of the university - houses much of the computing power installed at the University of Stuttgart. The technical building systems and the control technology are mainly from the 80s and 90s. As is common in data centers, power consumption is mainly caused by the operation and cooling of the computers. The heating power plant of the university supplies the data center with electricity, district heating and district cooling.
