The project

A modular turnkey data center cooled by Lake Geneva water


To improve the security and continuity of service as well as the overall energy efficiency of its data centers, the City of Lausanne entrusted Module-IT with the design of its main data center and the emergency room in September 2014. Based on a modular structure, delivery took place at the end of 2014 with commissioning in January 2015.

Module-it’s answer

To meet these needs, Module-IT opted for turnkey implementation of a modular data center and a second backup container data center. The main data center, with a computing density of about 80 kW, has the characteristic of being cooled by the water of Lake Geneva. The container (IT-box) and the technical infrastructures are located outside. The equipment is cooled by two groups of indirect free-cooling ice water. At both sites, the energy efficiency of the facilities was optimized, with target CPUEs of 1.2 for the main site and 1.4 for the secondary.

Project strengths

With the establishment of these two sites, Module-IT enabled the city of Lausanne to be equipped with secure data centers, ensuring continuity of service and producing low energy consumption.

Key figures
