Performance-driven Shape Memory-based kinetic solar shading design

This study presents an adaptive kinetic shading system developed to address climatic challenges in curtain wall applications. The system employs a lightweight and non-energy-dependent mechanism that optimizes both daylight control and shading. In order to be responsive and relying exclusively on natural resources, it incorporates a thermal-responsive component, exploiting Shape Memory Materials (SMM) to actuate dynamic reactions to environmental changes. The methodology encompasses three principal components: analysing SMM activation processes and temperatures, investigating kinetic movement patterns, and designing module geometry. The ultimate objective is to develop a design application suitable for both new and existing buildings, functioning as a secondary skin for curtain wall systems. Laboratory tests on scaled prototypes demonstrated the system's responsiveness and effective kinetic behaviour. Digital simulations further validated significant improvements in energy efficiency relative to buildings' consumptions. While ongoing research calls for enhancements in material performance and applicability, the findings highlight the relevance of this technology for developing improved climate-tailored designs.
