The Institut Bauen und Umwelt e.V. continues to grow: eight new companies from the construction and materials industry joined our network in the third quarter of 2025.

“We are delighted to welcome every new member who shares our mission and works with us to promote sustainability in the construction sector. Every new company strengthens the network, brings valuable perspectives and shows that responsible construction has long since arrived at the centre of the industry,” says Florian Pronold, Managing Director of the IBU.

With their membership, the new companies are setting an example of transparency, credibility and joint action. 

We warmly welcome them and look forward to exchanging ideas and working together!
