German exhibition centers seek to invest more than €1.2 billion in their facilities by the year 2022, primarily in modernizing their halls and, to a certain extent, in expansion as well. Further investments are planned for infrastructure and catering. Growing demands on sustainability and energy efficiency will play key roles here. These are the results of a survey carried out by the Association of the German Trade Fair Industry (AUMA) in February 2017 of 25 exhibition centers of national and international significance. Existing hall capacities of 2,795,509 m² are to be expanded by a total of around 55,000 m², representing an increase of 2% over five years.

In 2016, German trade fair companies invested a good €250 million in their exhibition and conference capacities, especially in the renovation and technical modernization of existing facilities. The capacities remained largely the same as the year before.

An AUMA survey in 2017 showed that exhibition centers of regional significance have a total hall floor space of 381,815 m², which means that Germany currently has nearly 3.2 million m² of hall space available for exhibitions.
