Alberzell production hall

The construction company's production hall was built using a reinforced concrete frame construction, with the columns consisting of recycled concrete containing 35% recycled aggregate. Furthermore, a clinker-optimised cement was used in the concrete production, which made it possible to reduce the CO₂ content. The truss construction and the ceiling were made of wood and can be completely dismantled without leaving any residue when the building is demolished. In order to allow the materials to be separated into their original form, no adhering building materials such as plasters or floor coverings were used.

A large part of the building façade, with an area of around 2,000 m², was made from rammed earth walls, which were produced from the excavated material from the construction project. The material was stored to the side, dried and enriched with locally sourced brick and concrete rubble before being built into 48 cm thick walls. A total of around 960 m³ of compacted mass from around 1,280 m³ of raw material was used. The development of the material was initiated by the construction company itself.

Sustainable design was also emphasised for the hall's energy supply. The roof was designed as a solar green roof made of solid wood, taking into account both functional and sustainable criteria. The building is heated by means of concrete core activation, which is connected to an existing wood chip heating system.
