The aim of the Koelnmesse 3.0 project is to create a Koelnmesse that perfectly meets the new requirements of organizers, exhibitors and visitors, while also ensuring the success of trade fairs in the future. Visits to events will be more convenient and the experience much more intense. The trade fair environment is becoming more attractive and the burden on the environment and energy consumption have already been greatly reduced. This modernization of the exhibition grounds, improvement of the traffic routes, new entrances and buildings are the prerequisites for Koelnmesse’s success as an economic engine. The first steps have been taken and the results show: It’s working!
