The new roof structure creates a consistent and smooth transition between the exterior and the interior of the building. It connects functional areas into one fluid space and creates an open and evocative atmosphere. The three-dimensional pattern on the roof was generated in a simulation of fluids based on particle flows. Liquids have three essential parameters: viscosity, density and surface tension. The interactions between these three physical properties have been tested on the computer in a series of variations to generate a coherent pattern with many holes.
The complex structure in exposed concrete was tested and optimized in 1:1 mockups. The finely triangulated surface of the concrete structure allows a subtle play of light and shadow and was achieved by testing different milling techniques. The advanced geometry of the roof and its construction process reflect the focus of the Building Academy in the field of concrete application.
