The Institut Bauen und Umwelt e. V. (IBU) continues to grow: in the second quarter of 2026, eleven companies and organisations decided to become members of the IBU. Together, they are helping to drive forward the transformation of the construction industry by providing transparent and reliable environmental information.

“Our network thrives on the knowledge, experience and commitment of its members. Every new member strengthens professional exchange and creates new impetus for sustainable construction,” said Dr Martina Bender, Managing Director of the IBU.
