Alnatura Arbeitswelt

DGNB Platinum Certificate for the new Alnatura headquarters – with a fire protection strategy implemented by D+H.

With a gross floor area of 13,500 m², the Alnatura Arbeitswelt is the largest building in Europe to feature a loam façade. The architectural firm "haascookzemmrich Studio 2050" put a great deal of thought into the sustainability of the building. And it shows – in several aspects. For example, the project was the first in the world to feature geothermal wall heating. In recognition of its sustainable architecture and high-performance building equipment, Alnatura Arbeitswelt has been awarded the Platinum Certificate by the DGNB (German Sustainable Building Council).
In addition, progressive building technology ensures safety inside the building. The fire protection strategy for the building specified a fundamental combination of natural smoke extraction solutions, sprinkler systems and machine-based smoke extraction. Furthermore, the four stairwells in Alnatura Arbeitswelt are designed to be divided into separate fire compartments, each with separate smoke vent lines. The side-hung windows located there were equipped with D+H chain drives from the KA Series for supply air. In addition, CDC Series chain drives were installed in the façade of the atrium. For the heavy skylight windows in the atrium roof, the technical planners opted for powerful chain drives from the CDP Series, which are being used exclusively for ventilation purposes here. For the smoke extraction and natural ventilation controller, those in charge of the project decided on the CPS-M from D+H. It is ideally suited for highly complex structures as well as for the three-storey Alnatura Arbeitswelt. This is because it features a modular design and the virtually unlimited power capacity that such a design offers. Alnatura Arbeitswelt was awarded the Platinum Winner and Special Innovation D+H Atmosphere Award 2019.
