Host your data in an ultra-secure environment

NDC continues its expansion with a new strategic site in the Île-de-France (Greater Paris) region, in Vélizy-Villacoublay.

Designed by Silvio d’Ascia Architecture and Egis for NDC, this new-generation data center offers unprecedented cooling flexibility, from 100% air cooling to 100% DLC (direct liquid cooling), to meet a wide range of cooling requirements.

Fitting seamlessly into its urban environment, the site recycles its waste heat to provide heating for the nearby student residence, built by IF Architectes for Cogedim.

This project embodies an exemplary approach to urban integration, and illustrates the expertise offered by Altarea Group, the French leader in low-carbon urban transformation.

NDC Vélizy is designed in accordance with Tier 3 of European standard EN 50600, which sets high standards of reliability for critical infrastructure.

This means that electrical installations, cooling systems, and network connections are all redundant, ensuring service continuity even in the event of equipment failure.

This level guarantees the absence of a single point of failure (SPOF) and ensures optimal availability for the most demanding applications.
