Although Messe München does have a tried-and-tested hygiene concept, BAU, the world’s leading trade fair for architecture, materials and systems, will not be held from January 11 to 16, 2021 as a conventional in-person event. This was the clear decision from the Messe München meeting with the Advisory Board and Board of Trustees of BAU on 30.09.2020. Instead, there will be a hybrid format from January 13 to 15, 2021, offering exhibitors the opportunity to present their innovations to a wide audience. The digital part of this event will also be an important part of the conventional in-person BAU 2023 trade fair.
