Aluminium facade from Novelis achieves DGNB platinum status

With its new training centre in Holzminden, Stiebel Eltron has set new standards for sustainability and quality. For sustainable building in compliance with the DGNB construction materials should be chosen accordingly to the strict environmental requirements regarding production and dismantling.

With its new training centre in Holzminden, Stiebel Eltron has set new standards for sustainability and quality. For sustainable building in compliance with the DGNB (German Sustainable Building Council), not only should the distances between manufacturing and the construction site be reduced, but most importantly construction materials should be chosen accordingly to the strict environmental requirements regarding production and dismantling. That is why the architects chose Novelis ff2 painted aluminium for the facade of the training centre.

The “Schneider die klempner gmbh” facade construction company gave the Energy Campus an attractive facade, mounting 2 mm thick coil-coated, full aluminium cassettes with an anodised look. Compared to off-the-shelf full aluminium made of the AlMg1 alloy, the AlMg3 alloy allowed savings of a third of the quantity of material, without having to reduce the size of the aluminium cassettes. The monolithic suspended cassettes at varying heights in a 150/300/600/900 mm grid give the building its dynamic effect.

A decisive factor in the choice of materials was the completely homogeneous dismantling and recycling properties of the facade. Full aluminium can be recycled problem-free and with absolutely no loss of quality, and an unlimited number of times, too. The 2,850 m2 ff2 painted aluminium facade plays an important role in the DGNB certification of the plus-energy building.

For the facade Stiebel Eltron chose the anodised colour C34, manufactured as painted aluminium using an environmentally and resource friendly coil-coating technique. The high-quality surface coating with 80% PVdF content has been tried and tested in construction projects around the world, demonstrating convincing weather resistance even under extreme climate conditions. The ruggedness of the paint and the low maintenance requirement were also important factors in the choice of materials for the Energy Campus. Moreover, painted aluminium with an anodised look offers problem-free processing, without the work and costs that would be involved with individually anodised elements.
