Abstract

The field of bio-mimicry binds two distinctive paradigms. One represents evolutionary processes of form and growth taking place in biological organisms, while the second represents processes of manmade designs.

These two paradigms share many important principles when referred to architectural design. Although buildings are not organisms in a biological sense, biology has always inspired human designs as a source of knowledge along the history, making a significant mark on architectural and engineering developments.

The research focuses on the concept of structural optimization as a major theme in morphogenetic processes for both biological and architectural designs.


In natural environment, forms of organisms evolve under changing conditions of loads and temperature. In this sense, the forms of all organisms represent a diagram of forces of the environment acting upon them as they emerge and evolve. Different organisms inhabit different environments as a continuous process of evolution makes them readjust to survive and ensure their next generations.

Since structural optimization is a mutual objective for both biological and architectural structure, one could expect resemblance in the design process. However, the morphogenesis of organisms and buildings, uses almost opposed mechanisms.

Biology constantly uses two seemingly contradictive mechanisms for morphogenesis. one is redundancy  - that produces a large diversity of morphologies , while the second, is selection - that eliminates all less fitted morphologies. This process of evolution, as a whole, keeps repeating itself until the best fitted morphology of the organism is formed to ensure its sustainability.


In contrast to biology, engineering and architecture, uses only selection as a dominant mechanism for form finding and avoid redundancy as much as possible. The objective is to reduce material, coasts, and energy.

The research aims to reveal the contribution of bio-mimicry to the latest practical as well as theoretical developments in architecture as a design paradigm. it also aims to explore the applications and production techniques of bio-mimetic principles in architecture.

The methodology of the research is based on a review of the development of bio-mimicry, and by analysis of case studies dating from early 20th century to latest digital design and fabricated structures.

The contribution of the research is the classification of bio-mimetic principles in architectural terms and revealing new knowledge in structural optimization and form finding processes.
