in the context of cladding double curved facades this becomes a very important
and game-changing characteristic. For although the meshes of double curved
façades may seem to have a smooth global appearance, they consist in fact of
thousands of individual panels, which render the use of standardised shading
devices practically impossible. Thus, applying a transformable shading system to
this kind of facade would require the individual scaling and distortion of its
components—a feature that elastic-kinetic structures can offer. Furthermore, the
Flectofin principle suits a wider range of applications, from small-scale micro-
systems to large-scale architectural building components.
