Revitalization of a listed skyscraper

Installation of building services in a 12-story hotel

The former Commerzbank high-rise building in Düsseldorf's old town has been converted  into a modern city hotel. ENGIE Deutschland has taken over the installation of  the building equipment during this revitalization, based on a finished design. The project received a DGNB platinum certification. 

The listed building has a height of 12 floors  and a narrow location,  which required logistically demanding handling.
