1.0 Introduction
Architecture has long been inspired by natural forms, where a building may reference a particular organic form yet may exhibit none of the physical advantages that it could lend to an innovation or extension of architectural technology. Alternatively, a building may not allude to an individual organic form yet its function with regard to structure, mechanical or circulatory systems may be a direct result of investigations into natural principles of design and construction. This report concentrates on the latter, where the architecture develops from or utilizes the biological science that it derives inspiration from.
The aim of an evolutionary architecture is to achieve in the built environment the symbiotic behavior and metabolic balance that are characteristic of the natural environment.
2.0 Definitions
2.1 Definitions:
The word biomimicry originates from the greek word bios, meaning life, and mimesis, meaning to imitate.
Biomimetics is a new discipline that studies nature's best ideas and then imitates these designs and processes to solve human problems. It is a way to observe nature in action and use that knowledge to inspire new ideas.
The science of biomimcry was solidified in 1997, with the book " biomimicry: innovation inspired by nature". Janine benyus, author of the book who provided us with a description of biomimicry and its significance to the way it can shape the future. Mimicking these designs and strategies could change the way human think in every field of life including architecture.
The process of biomimetics itself is interesting, relying on the fact that living organisms and engineers have a similar goal: to create a structure in the cheapest way possible-either in terms of energy or money.
Biomimicry can be applied to buildings in order to:
a- make materials stronger, self-assembling, and self-healing
b- use natural processes and forces for basic building functions
c- allow them to produce resources by integrating natural systems
2.2 Concept
By looking at biological and botanical life for ideas that can be exported to architecture branching, membranes, photosynthesis, leaf phyllotaxis,etc. an agenda of design concepts can be proposed that simulates desirable properties found in nature for deployment in building. Material scientists are looking to a process called biomimetic investigation where researchers look to natural forms of life and organic elements shells, fish, bacteria,etc. for properties such as hardness, lightness, softness,etc. to extract for new materials and new ways of manufacturing.
The concept of biomimicry in itself is nothing new. Human structures have borrowed from nature throughout history. Our first shelters, for example, were little more than upturned bird's nests: formed of branches and insulated against the elements by whatever materials were readily available. In fact, it could be argued that biomimicry is not a new movement, but a return to our earliest inspirations. New technologies, however, have allowed us to investigate and replicate systems that our ancestors were unable to exploit on grand scale.
2.3 Background
Organisms in nature face the same challenges we do, but they meet them sustainably.
Early humans learned hunting, shelter and survival techniques by observing animals as they interacted with their surroundings. While humans lacked the fierce claws and superior hunting instinct of bears, People could mimic their techniques. And as humans began to design ever-more complicated contraptions, they continued to look
to nature's example. From Leonardo da vinci's 15th-century sketches of flying machines to the wright brothers' first successful prototype four People have called on nature's inspiration throughout humans' history. By observing animals, plants and natural processes, we gain insight into what works and what does not. For engineers, these observations are helpful in both the design process and inspiring new inventions using natural technologies. With the concerns for the environment, biomimicry may offer suggestions of how industrial designs can be more sustainable and appropriate for different climates and cultures.

2.4 Objective
It is to nurture and grow a global community of people who are learning from, emulating, and conserving life's genius to create a healthier, more sustainable planet.
3.0 Biomimetic technology
3.1 Approaches to biomimicry
Approaches to biomimicry as a design process typically fall into two categories : defining a human need or design problem and looking to the ways other organisms or ecosystems solve this, termed here design looking to biology, or identifying a particular characteristic, behavior or function in an organism or ecosystem and translating that into human designs, referred to as biology influencing design.
Approach to biomimetic investigation
Approaches to biomimicry as a design process typically fall into two categories: defining a human need or design problem and looking to the ways other organisms, termed here design looking to biology, or identifying a particular characteristic, behavior or function in an organism and translating that into human designs, referred to as biology influencing design.
a- Define the problem & its context
b- Find organisms with a similar problem, see what they do , find many divergent organisms to see which has the best / most relevant strategy.
c-Translates the best strategy to a buildable thing, if necessary, find an expert to help.
The approach where designers look to the living world for solutions requires designers to identify problems and biologists to then match these to organisms that have solved similar issues. This approach is effectively led by designers identifying initial goals for design.
Carl hastrich suggested they represent the process in a spiral that would be visually understandable to designers. (fig.2)
Fig(2) Design spiral " design to biology approach |
An example of such an approach is daimlerchrysler's prototype bionic car (fig.2). the design for the car was based on the boxfish a surprisingly aerodynamic fish given its box like shape which make it more efficient in terms of fuel use. the chassis and structure of the car are also biomimetic, having been designed based upon how tree are able to grow in a way that minimizes stress concentrations.
3.2 Biomimicry principles
The biomimicry principles focus exclusively on nature's attributes; thereby implying that humans have much to learn from the billions of years of the natural world's evolutionary experience.
a- nature uses only the energy it needs
b- Nature fits form to function
c- Nature recycles everything
d- Nature banks on diversity
e- Nature demands local expertise
a- Mimicking a form or a shape from nature
For instance, you may mimick the hooks in an owl's feather to create a fabric that opens anywhere along its surface. You can imitate the frayed edges that grant the owl its silent flight.
b- Mimicking a process carried out by nature
The owl feather self-assembles at body temperature without toxins or high pressures. by way of nature's chemistry. The unfurling field of green chemistry attempts to mimic these beginning recipes.
c- mimicking a material and how it performs or mimicking of natural ecosystems
The owl feather is gracefully nested- it's part of an owl that is part of a forest that is part of a biome that is part of a sustaining biosphere. In the same way, our owl inspired fabric must be part of a larger economy that works to restore rather than deplete the earth and its people.
3.4 Biomimicry and architecture
Nature's designs are organic. Their shapes depend upon their functions. They are not linear. They are not based on lines and are therefore not limited by them. In nature, designs are organic; they are very small (only as big they need to be to fit the function). Human designs are very geometric and they are often larger than most natural inventions. Human's inventions are very brittle, stiff, and most of them depend on wheels for mobility.
Architects have long taken inspiration from nature. In ancient Egypt columns were modeled on palm trees and lotus plants, and building designers have borrowed the shapes and proportions of natural forms ever since as they strived to achieve aesthetic perfection.
Some architects now believe that such biomimicry has more to offer than simply making buildings look good. They are copying functional systems found in nature to provide cooling, generate energy and even to desalinate water. And they insist that doing these using biomimetic designs is not just a gimmick, but makes financial sense.
3.5 How may biomimicry changes our lives?
If we want to consciously emulate nature's genius, we need to look at nature differently. In biomimicry, we look at nature as model, measure, and mentor.
Nature as model: Biomimicry is a new science that studies nature’s models and then emulates these forms, process, systems, and strategies to solve human problems – sustainably. The Biomimicry Guild and its collaborators have developed a practical design tool, called the Biomimicry Design-Spiral-for-using-nature-as-model.
Nature as measure: Biomimicry uses an ecological standard to judge the sustainability of our innovations. After 3.8 billion years of evolution, nature has learned what works and what lasts. Nature as measure is captured in Life's Principles and is embedded in the evalute step of the Biomimicry-Desig-Spiral.
Nature as mentor: Biomimicry is a new way of viewing and valuing nature. It introduces an era based not on what we can extract from the natural world, but what we can learn from it.

4.0 Applications and analysis
4.1 Biomimicry inspires by animals
a Eiffel tower
Fig(6)The thigh bone |
Fig(5)The Eiffel tower |
It is an Exposition observation tower, it was made of Exposed iron, located on the Champ de Mars in Paris, Built in 1889, engineer Gustave Eiffel and its style is Victorian structural expressionist.
The Eiffel tower was built with a structure similar to that of the Thigh bone head. Thanks to this design, the tower acquired an unshakable structure that also solved the ventilation problem. The Eiffel tower's metal curves formed a lattice built from metal studs and braces.
Fig (7) The latticework, copied from bones, has become one of the basic elements employed in construction techniques today. It requires fewer materials, and makes for a building framework that's both strong.
.
Fig (8) Many architects and construction engineers duplicate the internal structure of bone, which increases its load-bearing capabilities. roofs can be built to cover large areas thanks to the use of ribbed structure similar to those in bone.
b Waterloo international terminal
Fig (9): The pangolin |
The terminal needed to be able to respond to changes in air pressure as trains enter and depart the terminal.
The glass panel fixings that make up the structure mimic the flexible scale arrangement of the pangolin so they are able to move in response to the imposed air pressure forces
c Spiral café
Fig (13): Shell |
The building form is inspires by the shapes of sea shells and pine cones to fractal patterns within galaxies. Illustrated graphically, the sequence forms a graceful spiral. The shape of the café was derives from extruding this 'golden' spiral along a tilting axis to form a simple curved enclosure.

Challenges solved Purchase, installation, maintenance of an air conditioning system for a building in Zimbawe has immediate and long-term costs. The challenge was to create a self-regulating ventilation system that would keep the building at temperatures that are comfortable for workers and residents.Differences from existing products Mick Pearce worked with the construction company Arup to design the structure, which is passively cooled.
Pierce was inspired by thermal control found in termite mounds.

b UAE pavilion
Fig(31): The dune |
A showcase of passive environmental design, the pavilion creates a symbolic reference with the desert landscape over which each of the seven emirates presides. As if modeled by prevailing winds, the pavilion mimics the duality between the rough and smooth sides of a sand dune while making the most of its site.
5.0 Conclusion
a- Biomimetic architecture as the new contemporary architectural style of the 21st century that will revolutionize the architecture world in every way either the way architects think or how they inspire their ideas, the used materials in building, finishing materials to the world and building users. However, architecture has a small role to play in our daily life but it has a great influence in the world we live in.
b- This adaptation of technology has peaked in the second half of the 20th century with the discovery of new conventions of different materials has led to an emerging new styles and patterns of thinking that has revolted the traditional way of thinking in architecture.
c- Design biomimetics is a bridge that can connect architectural and design professions on a route to linking designed and environmental.
d- Design biomimetics can emphasize ways of thinking and designing that bring architecture and industrial design into a process of environmental and biological focus on more responsive, safer buildings.
e- Biomimetic technology would help us also overcome environmental issues, such as the greenhouse effect, global warming, or even the Ozone hole. By reducing the vast amount of CO2 emissions from the built material, and purifying the surrounding environments. One has to predict that this impressive new technology will be necessary to use in this 21st century and we have to understand it well in order to be used in the right direction and contribute to the humanity development.
