The DGNB deconstruction certification promotes a systematic approach to preserving the building stock and maximising the value of existing building materials. In practice, this meant that the building had to be carefully dismantled and its resources safeguarded and reused.
Minimising energy and carbon emissions
Energy performance played a central role in the design of the new tower. The facade is fitted with solar panels designed to cover the building’s total energy requirements. Equally important is the choice of windows: 270 PVC windows from EgoKiefer. These windows contribute to the building’s sustainability profile as they significantly strengthen thermal insulation, helping maintain comfortable indoor temperatures while keeping energy consumption as low as possible. Furthermore, they are produced with almost 50% recycled PVC.
Meeting social needs for smaller apartments
The new tower has 37 apartments across 11 floors,while the former main building has been converted into 15 additional loft apartments. With a growing need for smaller apartments in the region, the redevelopment of the old mill helps address an important local housing challenge – further strengthening its long-term social value.
