Citibank Data Center, Frankfurt am Main

The world’s first LEED platinum certified data centre

This data centre in Frankfurt is Citigroup's largest outside of the United States.

Sustainability, conservation of resources and resilience standards were of particular importance to the project and a priority for the client.

Regular audits were undertaken throughout the project including the choice of European location, the design and facilities of the building and the choice of materials. The construction and operation of the project ensured that decisions were taken with sustainability as a key consideration.

The data centre plant topology, unit sizes and operating parameters have been selected to exceed reliability criteria and to enhance the operational energy efficiency.

Through a combination of energy-efficient technologies and innovative solutions, significant reductions in energy usage against conventional data centres were achieved. This included a reduction of energy use for the infrastructure of the data centre of 72% and a reduction of water consumption of 30%.

The project was designed to accommodate a phased delivery.
