Unidome is proud to present a project in which the world's largest wingspan is realized with a sustainable voided biaxial slab ceiling. As part of the new Loxone Campus in Kollerschlag, Austria, an auditorium with a roof of 33m x 21m is being built. The 90 cm thick, slightly curved panel is an architectural and engineering masterpiece, which is made possible not least by the use of Unidome XS-D3 hollow body elements. The Unidome concrete formers save 72 cubic meters of concrete and 180 tons of self-load in this ceiling. With this ceiling alone, 15 tons of CO2 emissions are avoided as a result of concrete displacement. Unidomes prevent more than 125 tons of CO2 emissions throughout the project — by the way. The exceptional application underlines the versatile use of unidomes for sustainable concrete structures of all types.
The unidome hollow body ceiling used here is based on the principle of biaxial load-bearing action, in which load-free areas within the concrete ceiling are displaced by specially shaped, recycled plastic hollow bodies. The Unidome XS-D3 void former modules used act as lost formwork and enable significant concrete savings without impairing the static integrity of the component.
This structural design not only reduces dead weight and improves load-bearing behavior over large spans, but also makes an active contribution to CO₂ savings, material efficiency and sustainability. The combination of lightweight construction, climate protection and architectural design freedom makes Unidome technology the ideal solution for demanding and resource-saving projects in reinforced concrete construction. This project thus once again underlines the advantages of Unidome voidformer technology in the context of sustainable construction.
