Energy-Efficient School Extension in Modular Construction with Special Slate Facade
The contract for the new school building of the Berufskolleg Oberberg in Wipperfürth was awarded to us as a modular construction company after the client decided in favour of the concept and the offer we had prepared.
The tender was for the design of the school building, the planning and execution of all construction work, the approval procedure and the completion of the construction work by the specified date with the submission of a fixed price.
A modular building with a slate façade is definitely something out of the ordinary. Our architect became aware of this new type of slate roof through a trade publication. The client was also enthusiastic about it, as Wipperfürth is located in the Bergisches Land, where the slate facade is part of the landscape and is appreciated as a sustainable and durable material.
Here, every stone is unique. The different heights and widths were processed by the roofers as required in a dynamic selection process, taking into account the height of the windows.
So that the modular building does not become too dark, the windows are colour-contrasted with the traditional Oberberg green tones. These colours are also found in the interior of the school building.
The installation of the window elements was not done in our factory, as is often the case, but on site, as these were used across the modules.
In only five months, the modular teaching building was constructed ready for use, including the elaborate earthworks and the construction of the foundation.
Access to the building is via two generously proportioned main entrances and a side entrance; a foyer was dispensed with. Upon entering the building, the light-flooded stairways attract attention.
The two school buildings are connected by a connecting corridor made of a steel construction with powder-coated panels.
Improved thermal insulation made it possible to achieve particularly good U-values (measure of heat transfer) for walls, roof, floor and windows. After completion of the modular building, a differential pressure measurement procedure (BlowerDoor test) confirmed excellent tightness.
