House of the Future in Bottrop / Germany
The outer envelope of the model building is fully insulated with polyurethane. Self-supporting, prefabricated elements from Logelis were used for the walls. They comprise a core of polyurethane foam encased in a thin layer of cement. The floors – with insulation boards from puren gmbh – and the drop ceiling likewise are insulated with polyurethane.
Thanks to the excellent thermal insulation of the wall panels, a wall thickness of only 16 centimeters was sufficient. The annual heating energy requirement is designed to be less than 15 kilowatt-hours per square meter, meaning the building fulfills the respective requirements of the passive house standard.

The ecological rehabilitation of an entire district – this unique project is currently being implemented in the former mining center of Bottrop/ Germany.
The InnovationCity Ruhr initiative hopes to serve as a prototype for the renewal of not just the entire Ruhr region, but other industrial metropolitan areas throughout the world. One of the lighthouse projects: a commercial building downtown that after extensive rehabilitation now generates more energy than other newly constructed buildings.
