THERMO TWIST – A Thermal-Responsive Sunshading Facade: Motor-Free Operation with Dynamic Aesthetics

This system features aluminum and carbon fiber rotating panels with a fabric membrane, using Nitinol wire springs for passive solar adaptation and a wishbone joint mechanism for synchronized movement and improved wind resistance.

Project information
This system is composed of aluminum/carbon fiber almond-shaped panels that rotate 0–90 degrees, with a fabric membrane spanning between them. Rotation is triggered by the linear thermal expansion of a Nitinol wire spring, enabling passive solar adaptation. A wishbone joinery system ensures uniform movement, while slipping mechanisms enhance wind resistance.
