Biomimetic Kinetic Shading Facade Inspired by Tree Morphology for Improving Occupant’s Daylight Performance

Abstract

Many recent studies in the field of the kinetic façade developed the grid-based modular forms through primary kinetic movements which are restricted in the simple shapes. However, learning from biological analogies reveals that plants and trees provide adjustable daylighting strategies by means of multilayered and curvature morphological changes. This research builds on a relevant literature study, observation, biomimicry morphological approach (top-down), and parametric daylighting simulation to develop a multilayered biomimetic kinetic façade form, inspired by tree morphology to improve occupants’ daylight performance. The first part of the research uses a literature review to explore how biomimicry influences the kinetic façade’s functions. Then, the study applies the biomimicry morphological approach to extract the formal strategies of tress due to dynamic daylight. Concerning functional convergence, the biomimicry principles are translated to the kinetic façade form configuration and movements. The extracted forms and movements are translated into the design solutions for the kinetic façade resulting in the flexible form by using intersected-multilayered skin and kinetic vectors with curvature movements. The comprehensive annual climate-based metrics and luminance-based metric simulation (625 alternatives) confirm the high performance of the bio-inspired complex kinetic façade for improving occupants’ daylight performance and preventing visual discomfort in comparison with the simple plain window as the base case. The kinetic façade provides daylight performance improvement, especially the best case achieves spatial Daylight Autonomy, Useful Daylight Illuminance, and Exceed Useful Daylight Illuminance of 50.6, 85.5, 7.55 respectively.

Development of Two-Step Biomimetic Design and Evaluation Framework for Performance-Oriented Design of Multi-Functional Adaptable Building Envelopes

“…while values for UDI are in the accepted range and above average, it falls up to 10% below UDI values in similar research. On the other hand, in similar comparison, values for Daylight Autonomy show slightly better results [28,30].…”

“…In a study conducted by [28] which is built on a top-down biomimicry morphological approach and parametric simulations, tree morphology is used to develop a multilayered biomimetic kinetic façade. This study incorporates a literature review which investigates the influence of biomimicry on the functions of kinetic facades and further extracts the formal strategies of trees for daylight control based on the biomimicry morphological approach introduced by [29].…”

“…It will feature how the guarantee of biomimicry takes an alternate shape concerning development, manageability, and society [6]. The result has demonstrated enlightening and complicatedly woven with the aims of the plan, helping people by cooperating with nature and science [7]. There are five design principles to guide people who practising ecological engineering.…”

Feasibility Study of Implementing a Bio-Inspired Building Envelope for Energy Harvesting and Visual Comfort Improvement

“…This is why it would be logical to consider the economic aspect of adaptive facade structures in the design process. Many of the adaptive facade proposed in the literature are deprived of this factor [30], [31], which makes the implementation of the nal product ambiguous or expensive to implement. Given the introduction above, the literature review, in Sect.…”
