pure statistics

The federal department for data processing and statistics (LDS) employs around 1,600 members of staff which are working on behalf of the federal state of Nordrhein-Westfalen. In order to account for the increase in required space for the data processing unites the existing structure along the Mauerstraße has been extended by a new building block at the Roßstraße. Planning was done by RKW while the construction works were executed by Bilfinger Berger. Both buildings are interlinked via a bridge and a media channel underneath the ground.
The new office block considers disability access, 145 parking spaces in the basement and functional areas for the data center as well as for a printing office and archives. The 950 sqm of the data center itself are functionally self-sustaining. In addition to safety measures according the resistance class WK4 the technical equipment provides for an autarkic area. The data center is certified Level 3 as per TÜViT.
The building reaches new dimensions regarding energy efficiency. Maintenance costs could be reduced due to the setting of benchmarks on energy consumption, innovative technical equipment and the buildings geometry.
