Eight completed and six currently active IBAs illustrate the attractiveness of the IBA as an instrument. In 2007, IBA Hamburg initiated the IBA meets IBA Network with the support of the M:AI Museum for Architecture and Engineering NRW as a coalition of former, current and interested future IBA stakeholders. The Network is supported by the Federal Ministry of Construction. The workshops are organised as required, roughly once a year and focus on open communication of the status of the current IBAs and quality assurance for the properties defined in the IBA Memorandum. The key question at these meetings is always whether and how the IBA instrument established in Germany can be developed to contribute to European planning and building culture.

The IBA process is critically monitored by a Council of Experts appointed by the German Federal Government. It is made up of renowned stakeholders from research and the trade, as well as representatives of municipalities and Federal States. It was launched in 2009. The Council, which convenes once to twice a year, aims to ensure compliance with the criteria of the IBA Memorandum and update them if necessary. The IBA process is also benchmarked against comparable innovative regional and urban development instruments at national and international levels.

OPEN IBA: A platform about international building exhibitions

Open IBA is a joint project of IBA Thüringen and IBA Heidelberg in conjunction with the IBA meets IBA Network.

A joint, bilingual website traces the development of International Building Exhibitions from its beginning in 1901 to the present day. It represents the changes over its hundred-year history with the help of selected project examples and explains the challenges and quality requirements of international building exhibitions.

In addition to this website, Open IBA also comprises a standalone exhibition that is available on demand and entirely free of charge. The exhibition is an open invitation to people all over the world to become an ambassador for the IBA format.
