Bio-interactive Kinetic Facade

The architectural shape of the façade defines its identity as well as interactions with ambient micro-climate forces such as solar radiation. Because of the dynamic nature of lighting and occupant locations, several concerns, such as heat gains and visual discomfort, must be addressed in real-time operation. Improving daylight performance while limiting eye discomfort for several passengers at the same time is difficult. However, combining morphological adaption biomimicry principles with dynamic, sophisticated fenestration, and human-in-the-loop technologies can lead to an ideal solution.

Why?

Because natural light, as a renewable and permanent source, has good physical, psychological, and mental benefits on occupants' health, one of the crucial themes for designing facades is giving sufficient useable lighting at interior space. In real-time operation, interactive kinetic façades, whether adaptive or not, modify their configurations in reaction to the building's ambient climate and occupant activity, therefore boosting inhabitants' well-being and productivity.

Biomimicry

Investigation of biomimicry-inspired daylighting guide systems yields a wealth of knowledge on building scale, system and movement kinds, influencing features, geometric shape, functions, ways of admitting daylight, and temperature. In general, daylighting guidance systems inspired by biomimicry have been employed in a variety of climates, particularly temperate and warm-desert climates according to the Koppen climate classification. The technologies are employed in the creation of adaptable and responsive envelopes, as well as kinetic shading facades. They regularly used smart and semi-transparent materials to create intricate, flexible, foldable, and hierarchical self-shading structures.

Because of the biomimicry approach's high potential for extracting technical solutions and the "lack of quantitative performance analysis of bio-adaptive building skins," there is an opportunity to develop an interactive logic to provide communication between multiple occupant positions and dynamic sun-timing positions. Furthermore, the logic may be extended to kinetic-responsive decentralized and human-in-the-loop systems to improve the visual comfort of several occupants at the same time.

Conclusion

The dynamic kinetic façade inspired by stomatal distribution and movement can fulfill the requirements for daylight performance and visual comfort. Because of the utilization of dynamic sunshine and varied occupant locations, the kinetic façade arrangement is participatory. Because of the dynamic properties of relevant aspects such as sun-timing positions, local climate variance, and numerous occupant positions, it is critical to enhancing the flexibility and performance of the automated process in façade design. Using interactive logic to allow communication between dynamic parameters is one method. The biomimicry morphological method may be used to construct an interactive logic to transform from static to dynamic in the design idea of kinetic shading façade. As a result, the plant's architecture, particularly the mobility principles of stomata at the micro-scale, is a source of discovering and extracting novel light-adaptive techniques.
