BIM-based parametric adaptive design of kinetic shell facades in buildings

Design processes need to consider building adaptation to the changing conditions of usage, environmental changes, and the changes in users behaviour. Technological advancements have allowed to develop and access distinct approaches in design, where interactive physical mechanisms can be built that respond to their environmental and surrounding conditions. This paper investigates the relationship between the technological advancement in kinetic shell structures over time, examines different kinds of adaptive kinetic shells, highlights the importance and advantages of these structures, and proposes a BIM-based parametric adaptive design for multi-functional kinetic shell facades. The paper proposes a parametric workflow to test adaptive kinetic façades for curvilinear buildings to enhance the sustainable performance of buildings by reducing solar radiation intake based on the location of the building and the time of the day. This workflow utilises energy simulation of an architectural structure using kinetic façade system to optimise the best solution of daylighting adequacy and thermal performance. The workflow was validated by conducting a case study. The study concluded that the developed parametric workflow can enhance the efficiency of architectural buildings on multiple sustainable and financial aspects. The study also approved the advantages of adaptive kinetic shell structure in multiple locations and under different environmental conditions.
