Circular construction
The new building complex replaces the old district administration office from 1978, which had previously been systematically dismantled. Over 90% of the materials were recycled or reused – a prime example of urban mining. Concrete, metals, plaster and other building materials were separated by type and returned to the material cycle. This consistent conservation of resources continued in the new building: around 61% of the concrete used is made from recycled material, including the floor slab and numerous walls, ceilings and columns.

Cubic building complex
Two polygonal structures form a striking building complex, which presents itself as a horizontal figure of eight in the floor plan - a symbol of connection and continuity. The two parts of the building are functionally linked via a light-flooded foyer and a walkway on the second floor. With around 33,000 m² of net floor space, the new building offers space for 675 modern workstations as well as central facilities such as meeting rooms, a vehicle registration office, a day care center and a canteen. The spatial concept follows a clearly structured three-zone model with public, semi-public and internal areas - flexible, functional and geared towards future requirements.

Sustainability as a guiding principle
The new building meets the KfW Efficiency House Standard 40. Four heat pumps, fed with water from the Neckar, provide heating and cooling via ceiling sails. A photovoltaic system with an output of 481.5 kWp - integrated into the roof and façade – covers up to 85% of the electricity requirements. Cradle-to-cradle-certified products and FSC/PEFC-certified wood were also used in the interior fit-out.

An administrative building with a future
With the new Esslingen district administration building, ZÜBLIN shows what sustainable construction can look like today: resource-conserving, energy-efficient and architecturally sophisticated. A project that not only strengthens the district of Esslingen, but also serves as a model for public building projects.

The project is also aiming for DGNB "Sustainable Construction Site" certification and DGNB Gold building certification.

Certified by the German Sustainable Building Council (DGNB)

Ed. Züblin AG is pursuing several goals with this project: A sustainable construction site organisation, the conservation of resources as well as the minimisation of emissions, responsibility for the health and well-being of the builders, the cultivation of good neighbourliness and, of course, high-quality construction. For this, Ed. Züblin AG was the first company to be recognised by the German Sustainable Building Council (DGNB).
