Offenbach is getting a new high-rise building called Namu on the Nordkap site. Since the Expo Real in the fall of 2022, it is also clear that it will be a timber hybrid and will have a facade with photovoltaic elements. Now there is more information from the architect Eike Becker from Berlin.
The columns and beams of the new high-rise building will be made of timber, of so-called laminated timber beams. This is a technically very innovative material, which represents an improvement over conventional wood in terms of fire technology and statics. The timber elements to be installed are glued together at high temperatures and pressures in such a way that they are thermally more stable and have better building material properties in many respects.
Like the stairwells, the elevator shafts and the underground parking garage, the intermediate ceilings of the Namu will be made of reinforced concrete. Despite this, it was possible to significantly reduce the proportion of concrete in the design compared with conventional buildings.
