New Office Building

- case studies and pilots in BAMB

The pilot project “new office building” is located in Essen, Ruhr-area in Germany, directly on the UNESCO world heritage site of “Zeche Zollverein”, a former coal mine industrial complex, visited by over 1,5 million people per year. The demolition of pre-existing structures has already taken place, and the client has taken over the site as a prepared brown-field. The new office building will host over 200 high quality office workplaces for a local client. The total gross floor area will be 9598 m², with a total gross volume of 38781,87m³. The building will be an example of sustainable design with a special focus on the Cradle to Cradle-Design principles with respect to transformable and recyclable design, healthy materials and the use of materials passports. The 4000 m² Rooftop Garden will be accessible to the public.

“Many clients of Drees & Sommer are extremely interested in transformable buildings and the benefits of Materials Passports implementation, but they do not want to be the first movers. We want to give them a reference building and push the future market. Previous developments regarding sustainable building design have shown that pilots can make the difference as they give users a strong argument to demand this new quality from developers. On the other hand, pilots reduce risks for developers as they have a built reference for calculation security.”

The project will integrate transformable design and Materials Passports under realistic construction conditions. The target is to test and search for the limits. Therefore the two aspects “transformable design” and “Materials Passports” are applied under the realistic background of a project development scenario on the German market. The planning and development process will develop best practice solutions which can be adopted or even copied for other buildings. In this context, the pilot will offer ideas and solutions for other building projects to address the BAMB-targets. The waste reduction will be compared to a conventional building of the same size. Different stakeholders of the supply chain will be integrated to confront different parties with the ideas of Reversible Design and Materials Passports and to generate solutions together especially under the conditions of the German market. Completion is planned for end of 2017


  • Objectives:

The pilot aims to show the possibilities of the BAMB-targets under realistic market conditions – also addressing the narrow financial boundaries of real estate investors and an ambitious schedule.
