The office in Stuttgart is the hub for the entire activities of the DGNB. It controls the entire certification process from project registration up to the awarding of the certificate, holds training courses, coordinates and supports the DGNB Expert Pool, implements international activities and cooperations, organizes workshops and events, finds speakers and handles the issuing of publications. In addition, the DGNB office supports the Board of Directors in the organization of the general meeting of members and the committees in their work. It is the interface for the exchange of information for all members, builders and auditors.
