ABSTRACT

The R&D project ADAPTEX aims at developing a novel sun-shading system that contributes to a building's efficiency without taxing the economy of its subsystems. By exploiting the potentials of textile construction and the integrity of Shape Memory Alloy (SMA), significant reductions in material weight and operation energy for a dynamic shading system can be achieved. SMA elements are generally very suitable for construction applications due to their ability to be maintenance free and function without showing wear during performance. These materials are designed to function with a decentralized control system through electric current, but the design system is complimented by activity driven by changes in the environment that allow for autonomous and adaptive reactions to external stimuli like ambient heat or solar radiation. One of the primary advantages of using SMA driven technologies is the ability to eliminate complex motors and driving mechanisms. Because SMAs are designed for the accuracy and standards of mechanical engineering rather than for architectural facade applications, this engineered technology grants more control to the user than ever before. ADAPTEX closes the inherent gaps established in systems engineering by integrating SMA wire into large scale architectural surfaces while using light weight textiles with material technologies. When SMA is Implemented into soft structures it has the ability to initiate changes in geometry through the variations in temperature controlled by a façade's ability to shade or reflect light to enhancing building performance. Through various steps of ongoing prototyping and testing, the R&D projects proves the sun shading and façade integration potential to show significant results in building performance with ADAPTEX technologies.
