With the realization of comprehensive new construction and renovation measures, koelnmesse is pursuing the target of becoming one of the world‘s most sustainable and attractive inner-city trade fair centers by 2030. The measures focus in particular on the new, more flexible requirements of trade fair exhibitors and the design of the exhibition halls as event areas through greater attractiveness and comprehensive technical equipment.
As part of the project „koelnmesse 3.0“ , ZWP Ingenieur-AG has been commissioned with the planning services for the technical building equipment for three new buildings: the new Hall 1, Confex® and Terminal. In addition, the façade in front of Halls 10, 11 and 2 and the „Boardwalk“ connecting Halls 2, 3 and Confex® in the outdoor area are to be upgraded both aesthetically and functionally.
Despite all the diversity, the three new buildings have in common that they should be integrated into the existing energy structures of koelnmesse. The energy demand, which will increase due to the expansion of the south halls, will be largely ensured by the expansion of the existing supply structures of the refrigeration technology. For this purpose, a new refrigeration center with a cooling capacity of around 10 MW will be built at Confex®. In part, however, existing capacities can also be used to supply the new buildings through koelnmesse‘s local refrigeration network as a result of the removal and renovation. The heat demand of approx. 7.45 MW of the new buildings is supplied by the existing local heating network. Drinking water and the main electrical supply for the new buildings will be connected via the existing „energy channels“ on the exhibition grounds. The supply of the new Hall 1 and Confex® follows the proven principle of a media duct below the exhibition level. From here, the individual stands can be flexibly supplied with drinking water, waste water, compressed air, electrical and data systems, and sprinkler systems during the trade fair. In addition to the high-quality equipment standard of the koelnmesse, a major challenge of the new buildings is the adequate supply of fresh air to the visitors and the dissipation of thermal loads, as the occupancy densities can be up to two persons per square meter at peak times. To ensure this, ventilation and air-conditioning systems will be installed on the roofs of the new buildings, which will be equipped with high-quality heat recovery, among other things, in accordance with the latest efficiency requirements. The equipment is of extremely high quality, especially in the plant groups of the communications technology. The provision of intelligent people counting and tracking supports, among other things, improved routing within the new buildings. In addition, a platinum-level certification pursuant to the standards of the German Sustainable Building Council (DGNB) is to be achieved for the Confex® building.
