The German Sustainable Building Council (DGNB) has awarded Deutzer Hafen a PLATINUM pre-certificate. With an overall score of 83.3 per cent, the district is already better than required to achieve the top category, long before it is actually built. Among the five main criteria of the certificate, Deutz Harbour scored above average, particularly in the disciplines of 'socio-cultural and functional quality', 'ecological quality' and 'process quality'. Implementation of the requirements is described in the Sustainability Manual, which is updated regularly, and is reviewed by the DGNB on a regular basis. The certificate was last renewed in June 2023 following a successful audit.
