ItemAdaptive biomimetic façades: compound bio-inspired design strategy for multi-functional stadiums( 2016)In contemporary stadium architecture, there is a growing interest in pursuing environmental adaptability and multi-functionality for stadiums, due to the negative socioeconomic effect caused by the excessive energy consumption during the mega-event and low efficiency of the post-event use of these venues. To achieve these goals, most preceding research on contemporary multi-functional stadiums has focused on either one-dimensional mechanical transformation in stadium façades to expose part of the stadium to daylight, or limited reconfigurations of the interior architectural elements for various needs. Only few research studies and projects have explored dynamic adaptations of the stadium façade via novel transformations that could constantly attune the shape and structural configurations to reduce building energy consumption and meet diverse functional demands. The aim of my thesis is to introduce a novel design strategy to generate an architectural design concept for adaptive building façades that are capable of regulating environmental factors with adaptation strategies inspired by nature. The emphasis is on the potential of integrating two different biomimetic design strategies to create a synergetic effect from a daylight-related performative perspective: an evolutionary design process to generate the façade’s form via the genetic algorithm and adaptive mechanism inspired by the optical principles of the reflecting superposition compound eye. The hypothesis tested in this thesis is that the adaptive façade system developed by the compound bio-inspired design strategy from these two inspirational design approaches has profound implications in improving multi-functionality and adaptivity of the stadium by regulating the indoor illuminances conditions. This hypothesis was tested in three ways: -by analysing stadium design paradigms and multi-functional strategies adopted by the contemporary stadiums -by developing an integrated bio-inspired design strategy according to the problem-based biomimetic design approach ii -by evaluating the significance of the proposed design strategy via design prototype simulations. I assessed the design prototypes in simulation environments based on dynamic daylight performance metrics in consideration of their responses to the functional illuminance requirements. The integration of the proposed biomimetic strategies resulted in the enhancement of the level of adaptiveness of stadium façades in response to the external (lighting) and internal (functional) stimuli. As a result, the proposed compound bio-inspired design strategy led to the rich diversity of geometric forms via the evolutionary design process and dynamic adaptation for the stadium façade via exploratory investigations on nature’s strategies. My thesis concludes that the proposed compound biomimetic design strategy can establish more synergistic and interconnected relationships between nature and design activities, and facilitate the transitions of biological knowledge to the architectural design context. Further, the proposed biomimetic design exploration models and biological analogy search method can potentially be tailored for various design scenarios in different contexts. The integration of the strategic design approaches from multiple perspectives can create a novel design strategy that can expand the realm of design research on building performance and identify new possibilities of regulating environmental factors towards adaptive architecture.
