“…Since the solutions found in nature to problems of extremes are already optimized, the design process of kinetic facades could benefit from the combination of the solution-based and the problem-based approaches. These two approaches bring multi-functional solutions to design problems [31] and have their benefits and downsides. Importantly, the two biomimetic design methods are technology oriented and the integration of both methods could complement the simulation and experimental design approaches of kinetic facades, which are performance oriented.…”

Climate change, increase in CO2 production and energy consumption are major global issues and the building, environmental and construction sector is contributing to the increasing concern day by day. Due to increasing demands to satisfy environmental, social, and economic requirements, designing efficient and sustainable buildings has become increasingly complex. Today, the tendency towards sustainability has created new design approaches regarding adaptable kinetic building envelopes, amongst all, biomimetic design principles have gained interest. As opposed to traditional methods, the implemented biomimetic design approach in this research can assist in finding solutions for complex real-life problems regarding the adaptability of kinetic facades to achieve robustness, tractability, low solution cost and better rapport with reality. Design frameworks introduced to this day either do not incorporate bio-inspired concepts or are not able to map potential trade-offs in the performance of multi-functional biomimetic adaptable skins, effectively. Therefore, a flexible and expandable framework is necessary to go beyond project-based frameworks applied to case specific conditions. To design for performance, this research proposes a framework and aims to integrate different biomimetic approaches to assist designers and researchers in two steps to design and evaluate kinetic facades in different phases of development.

“…In the building sector, the practice of bioinspiration has led to multiple bioinspired buildings designs, but most of them are monofunctional designs, where the inspiring species demonstrate multifunctional features [8]. The assessment of the building performance is often not carried out, which can be seen as a shortcoming [9]. In an effort to tackle these challenges, the authors experimented with a bioinspired framework [18] that they adapted from an ISO standard design process [19], with the aim of proposing a multifunctional design for the building envelope.…”

“…Rising as an innovative approach, bioinspiration in the building field is the topic of extensive research; it mainly focuses on design processes, frameworks, and tools to ease the transfer of biological principles into technological responses [6][7][8]. Some research has already led to several adaptive case studies, but very few propose performance assessments of their design [9].…”

Building envelopes can manage light, heat gains or losses, and ventilation and, as such, play a key role in the overall building performance. Research has been focusing on increasing their efficiency by proposing dynamic and adaptive systems, meaning that they evolve to best meet the internal and external varying conditions. Living organisms are relevant examples of adaptability as they have evolved, facing extreme conditions while maintaining stable internal conditions for survival. From a framework based on the inspiration of living envelopes such as animal constructions or biological skins, the concept of an adaptive envelope inspired by the Morpho butterfly was proposed. The system can manage heat, air, and light transfers going through the building and includes adaptive elements with absorption coefficients varying with temperature. This paper presents the developed framework that led to the final concept as well as the concept implementation and assessment. A prototype for heat and light management was built and integrated into a test bench. Measurements were performed to provide a first assessment of the system. In parallel, geometrical parametric models were created to compare multiple configurations in regards to indicators such as air, light, or heat transfers. One of the models provided light projections on the system that were compared with measurements and validated as suitable inputs in grey-box models for the system characterization.

“…The 60-degree intersection angle (Figure 3) of the tensile cable structure was chosen as it follows a logic such as those found in the branching patterns. While the units were developed within full biomimicry parameters, the structure supporting the units has a bioinspired approach, which is an approach based on observation of biological systems rather than translating biological function into a viable model (Cruz et al, 2021).…”
