In June 2007 HOCHTIEF became one of the founding members of the German Sustainable Building Council and is actively involved in the management of this association. The council is made up, among others, of architects, investors, contractors and scientists. The organization aims to consistently promote sustainable construction and operation of building structures in Germany and create sustainable living spaces. A building certificate should enable this aim to become a reality in the foreseeable future. The certificate is intended to be awarded to projects which have stressed the importance of human health and resource conservation criteria during the planning and construction phases.

Sustainable construction increasingly enters the public eye, and the desire to exchange ideas and experience in connection with this important topic also manifests itself in the construction industry. The German Green Building Council (DGNB) now provides the first platform in this field by organizing "consense", the International Congress and Trade Fair for Sustainable Building.
