Open, simple, resource-saving and for people: The new building of the Alnatura working environment
In Darmstadt, Alnatura Arbeitswelt is an architectural milestone in terms of sustainability, material efficiency, openness and modern forms of work. One of the special features of the building on the Alnatura Campus, designed by haascookzemmrich STUDIO2050, is the use of an innovative rammed earth façade, which was the first in the world to be covered with geothermal wall heating. The sound-effective wooden slat ceiling, which spans the atrium and the completely open office areas, is also unusual.
The building on the site of the former Kelley Barracks, which hardly resembles a conventional office building, offers space for up to 500 employees on three floors with an area of approx. 10,000 square meters. Architecturally, the house is not intended to impress, but to invite. It is open to the environment, to new ideas, to people. A workshop for ideas that captivates with its simplicity. [...]
Innovative rammed earth façade
One of the special features of the building is a rammed earth wall, which was created in collaboration with Martin Rauch and Transsolar. The individual rammed earth blocks were layered on the north and south façades to form 16 self-supporting wall panels, each 12 metres high. The prefabricated rammed earth elements, which were prefabricated directly next to the construction site, have 17-centimetre-thick core insulation made of recycled foam glass gravel. In addition, material from the tunnel excavation of the Stuttgart 21 railway project was reused in the walls. In order to counteract the surface erosion of rammed earth, horizontal erosion brakes made of clay and trass lime are installed in the wall. The embodied energy in the production, processing and possible dismantling of clay is practically zero. The durability of the material, as well as the excellent humidity regulation and heat storage capacity of the clay, result in a building of high value stability. The surface remains free of algae or moss formation, and there is no need to clean or maintain the façade.
