This system is widely used in the north of Europe and involves using the positions of the façade wall so become structural elements. The walls can be made of two-layer load-bearing concrete panels separated by insulation.
This system simplifies the number of operations, as the load-bearing panel is at least the equivalent of two pillars, a girder and a wall panel combined.
This is an excellent structural option in buildings where the architecture provides the skin around the structure sufficient solidity to serve as a structural element and simplify the technical requirements of the structure.
