TU Deflt's Bucky Lab: Star-shaped sun shading

The projects and prototypes presented here not only showcase the inventiveness of the Bucky Lab students, but also lead to applications that can be used in actual buildings in cooperation with industry.

In case you don't know or have forgotten what the Bucky Lab is:
Here is a little introduction to the TU Delft's Master's degree course

Students Tjerk Doeschate and Justin Liem have developed a sun protection system that allows shading in the space between the facades using stretchable cloths. Driven by an integrated cable pull mechanism, the two layers of fabric that make up the Stretch Shading prototype can be opened or closed independently of each other.

These detailed images show the prototype with the inner layer open as well as the sun protection with the inner layer closed (white fabrics) and outer layer closed (black fabrics). The top image also provides a glimpse at the cable pull system.

Shading or darkening can be achieved by selecting different cloths. The shape of the individual elements in their superimposition creates a star pattern that gives the facade an interesting appearance both from the inside and from the outside.

To what extent such stretchable materials are suitable for continuous utilisation in the building envelope is currently being tested by industrial partners, as the UV resistance of the fabrics must be guaranteed.
