The Congress Center Hamburg in the final for the German Sustainability Award Architecture 2023


The finalists of the German Sustainability Award in the category Architecture 2023 have been announced. We are in!

The Federal Office of the German Alpine Club in Munich, the Congress Center in Hamburg and the U-Halle in Mannheim impressed the jury with their innovative solutions and present exemplary approaches to dealing with existing buildings.
“The three finalists for the German Sustainability Award for Architecture find answers to one of the greatest challenges of our time in very different ways,” says DGNB President and Jury Chairman Prof. Amandus Samsøe Sattler. “The preservation of existing buildings and their sensible continued use is not only elementary for achieving climate goals. It is also always about strengthening the identity of neighborhoods, cities and regions through an evolved building culture. This value should become even more apparent to building owners in order to avoid demolition. The finalists show how the preservation of existing buildings can be outstandingly successful, both in terms of design and building technology for further use.”

We are very proud to have been involved in the revitalization of the Congress Center in Hamburg. We congratulate everyone involved!

The German Sustainability Award for Architecture is being presented for the 11th time by the DGNB and the Stiftung Deutscher Nachhaltigkeitspreis e.V. (German Sustainability Award Foundation). The winning project will be announced at the 16th German Sustainability Award in Düsseldorf on November 24, 2023.

Half a century ago, the CCH – Congress Center Hamburg, a terraced concrete building with an adjacent high-rise hotel, was considered one of the most modern and largest convention centers in Europe. Built in 1973, this architectural masterpiece has since undergone an impressive transformation. The agn Leusmann/Tim Hupe Architekten consortium has modernized the CCH and geared it to the requirements of the future.

One of the most outstanding changes is the introduction of a new representative entrance hall, which complements the listed ensemble. This architectural intervention not only creates a contemporary reception zone, but also integrates innovative climate concepts. The building’s new façade features cantilevered ceiling panels that serve as solar shading. This, together with intelligent control of the façade openings, makes it possible to dispense with energy-intensive air conditioning.

By skilfully adapting to changing requirements, energy-efficient refurbishment and respectful treatment of the original building, the CCH is now an extremely flexible and contemporary venue. It combines state-of-the-art technology and sustainability to meet current demands.
