Designing Adaptability Strategy to a Novel Kinetic Adaptive Façade (NKAF): Toward a Pioneering Method in Dynamic-objects Daylight Simulation (Post-Processing)

The design and evaluation of adaptive facades (AFs) have become increasingly complex due to advancements in morphology, control strategies, and adaptability techniques. This study introduces a Novel Kinetic Adaptive Facade (NKAF) incorporating photovoltaic (PV) panels and Plexiglas to enhance daylight and view performance in office buildings. The research focuses on two objectives: (1) the innovative design of the NKAF, and (2) dynamic assessment of its daylight performance using advanced simulation methodologies. Annual daylight simulations, conducted with Radiance and a cutting-edge dynamic-objects workflow, evaluated three adaptability strategies: blocking direct sunlight, tracking solar trajectories, and minimizing facade movement. Results indicate that the fully dynamic sun-blocking logic significantly improved useful daylight illuminance (UDI 100-3000 lux) from 49% to 90%. Additionally, post-processing with NSGA-II multi-objective optimization provided an optimal framework for annual performance, effectively balancing multiple design goals. This novel methodology enables the simulation of dynamic environments and facades, addressing a key gap in previous daylighting research.
