ArcelorMittal

The location of the new headquarters building reflects ArcelorMittal’s historic ties to Luxembourg,   where the company has its head offices as well as five industrial sites producing or processing steel.  

Designed by Wilmotte et Associés, with a detailed brief to ‘design a modern, sustainable building that harnesses all the potential of steel from top to bottom’, ArcelorMittal's new headquarters, ArcelorMittal Kirchberg, is a showcase for the use of steel in sustainable construction. The building incorporates 10,000 tonnes of ArcelorMittal steel, mainly produced in Luxembourg from recycled steel. The beams are made from XCarb® recycled and renewably produced steel, which has a carbon footprint that is seven to eight times smaller than conventional steel, representing a saving of more than 10 tonnes of CO2 per beam. In this way, ArcelorMittal Kirchberg serves as an exemplar of how low carbon-emissions steel can be used in construction. 

The building will have a crystal-like appearance, thanks to its structure which is based on an exoskeleton, which spirals outwards and opens onto the city through a façade covered in plants. In addition to its contemporary architecture, the new headquarters offers flexible, modular working and living spaces to ensure a great working environment for employees. For example, each of the 2,600 workstations will benefit from natural light.  The building will fully be aligned with three major environmental labels: BREEAM (outstanding level), DGNB (Platinum level) and WELL (Gold level). The completed building will also be a showcase for deconstruction and the reuse of steel in the construction industry.
