adaptive sun-shading, textile building envelope, smart materials, autarkic operation and control mechanism, Shape Memory Alloy (SMA)


The research project ADAPTEX pursues the goal of developing adaptive, energy-efficient textile sun
shading systems using the smart material Shape Memory Alloy (SMA). Within this approach lies
a high potential for novel sun protection systems demanding little energy or even self-sufficiently
adapting to external stimuli while reducing operation and maintenance costs and at the same time
offering solutions to tackle growing demand for sun and glare protection. A Design Categories Matrix
is presented that brings together various involved fields from textile design and façade construction to
smart material development. Based on this, two concepts have been further elaborated: ADAPTEX Wave
and Mesh. Both incorporate SMA into textile structures but express different design and performance
potential by changing the geometry and openness factor of the surface area. For further evaluation,
various functional prototypes that scale up from 0.2 x 0.2 m to 1.35 x 2.80 m are developed and
reviewed. The buildability and functionality of SMA-driven textile sun shading systems that incorporate
requirements from the various involved fields are verified. The feasibility of parallel ADAPTEX Wave
and Mesh were assessed in comparison to the performance of state-of-the-art sun shading systems.
The technological ideas are subsequently optimised and scaled up in various cycles for follow-up testing
in both indoor and outdoor environments.
