Tessellation-Based Origami-Inspired Movable Façade for Daylighting and Exposure Optimization: Assessing Different Movement Approaches

This study emphasizes the importance of daylight performance in interior spaces as a critical factor in achieving global Sustainable Development Goals, including energy efficiency, environmental sustainability, and healthy living conditions. It introduces a novel façade system inspired by tessellation-based origami principles, designed to mitigate exposure, glare and optimize daylight utilization, directly contributing to user comfort and well-being. The research employs a movable folding façade system with modular adaptability through different tessellation patterns. Performance analyses were conducted to evaluate the system's effectiveness in reducing exposure (Annual Sunlight Exposure), glare (Glare Autonomy) and improving daylight performance (Spatial Daylight Autonomy). The system’s compliance with LEED v4.1 criteria was also assessed to ensure alignment with sustainable building standards. The proposed façade system effectively reduced overexposure levels to 2.42%, enhanced sDA to 87.87% and also improved glare values by up to 50.26%. These results highlight the system’s potential to improve daylighting performance while addressing user comfort. This research presents an innovative façade system that integrates tessellation-based origami principles to optimize daylight performance. It contributes to sustainable architectural practices by demonstrating the transformative potential of movable and adaptive façade designs in achieving sustainable development goals, addressing both environmental and user comfort.
