Lessons from NatureL’architecte du futur construira en imitant la nature parce que c’est la plus rationnelle, durable et économique des méthodes --- Gaudi
Although human ingenuity makes various inventions it will never discover inventions more beautiful, appropriate and more direct than in Nature because in her nothing is lacking and nothing is superfluous.--- Leonardo da Vinci
The engineering skill that goes into a beaver dam rivals the elegant calculations that built Pyramids and the Panama Canal -- Gould and Gould ( 2007)

Characteristics of Nature runs on sunlight; uses only the energy it needs; fits form to function; recycles; rewards cooperation; banks on diversity; demands local expertise; realises the power of limits.
Benyus (2002)

Much of our aesthetic is derived from an organic and fluid language that you find in Nature.
It involves complex, three dimensional geometries but there is always a rigorous logic behind them.

Science and Nature
Scientists aspire to replace many of the essential features of photosynthesis---- the process by which plants use sunlight to produce oxygen and organic molecules.

The Artificial Leaf
Research groups are now trying to create artificial leafs by using ruthenium and manganese complexes to try and mimic natural processes.
An Artificial Leaf would split water to produce oxygen and hydrogen, use hydrogen either as a fuel or to reduce carbon dioxide to produce organic fuels.

The sensing function proper is carried out by living cells but often the hierarchical organisation of the materials and structures can amplify signals (vibration, temperature, deformation, etc.)

Highly Integrated Hardware-Software Systems
Most biological sensors can achieve sensitivities comparable to thermal noise (~ 10-21W/s) and detect energies typical of single quanta

What Do We Expect from an Intelligent Building?
Carry structural loads (external, internal)
Provide shelter
Interact with environment (external, internal)
Control internal environment (sensing, actuation)
Adapt to changes in environment (sensing, actuation)
Integration of functions
Jeronimidis, G, 2007, The University of Reading
![Page 22: Prof Derek Clements-Croome - Sustainable architecture](https://reader034.vdocument.in/reader034/viewer/2022051113/55ce25ffbb61ebe9068b4659/html5/thumbnails/22.jpg)
Structural Loads and Shelter
Are the materials we use the best ones for the job ?
Can you build a 2km high building with existing materials?
What would be the challenges ? And the advantages?
Existing construction materials are probably not suitable
not enough strength and stiffness
too high a density
not particularly good for implementing functional integration
![Page 23: Prof Derek Clements-Croome - Sustainable architecture](https://reader034.vdocument.in/reader034/viewer/2022051113/55ce25ffbb61ebe9068b4659/html5/thumbnails/23.jpg)
Animals and Plants have evolved various strategies for dealing with these problems (thermal insulation, cooling – radiating surfaces, blood flow), light interception (plants)
In addition, plants are unique in being able to convert solar power into integrated functionality
Except for colonies (ants, bees, termites, …) the individual organism is the sole occupant of his “building”
Jeronimidis, G, 2007, The University of Reading
![Page 24: Prof Derek Clements-Croome - Sustainable architecture](https://reader034.vdocument.in/reader034/viewer/2022051113/55ce25ffbb61ebe9068b4659/html5/thumbnails/24.jpg)

Nature has always been architecture’s chief muse. The earliest Greek temples, made at first, from tree trunks, gradually honed into the ancient architectural orders, were an early attempt at reconciling Nature and man in architectural form.

Organic Architecture
Organic architecture promotes harmony between human habitation and the natural world through design. Sympathetic and integrated into its site so that buildings, furnishings, and surroundings become part of a unified, interrelated composition.

Patterns in NatureThe Fibonacci numbers 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144………frequently occur in Nature. The seeds of sunflowers and daisies have spiral patterns. Daisies have 21 clockwise and 34 anticlockwise spirals. Similar patterns occur in pine cones and pineapples. Petals number 3 for lilies, buttercups 5, delphiniums 8, marigolds 13, asters 21, daisies 34, 55 or 89 and sunflowers 55, 89 or 144

Patterns in Nature
If you take Fibonacci numbers as successive ratios
8/5, 13/8, 21/13, …….then the ratio values approach the golden number φ=1.618. The golden ratio is φ : 1 which is associated with aesthetics in art and architecture.

Dual Purpose Nests
The false flap above the apparent entrance is always closed but has here been opened to reveal the true way into the nest. Such nests are sometimes used after breeding by adult birds for shelter at night.

The egg storage nest built by penduline tit is one example of protection against predators. The apparent entrance (shown dotted) leads only into an empty pouch.

Hexagonal Bee Cells
Give compact and lightweight construction,for storage ;the developing larvae are fed by worker bees up to 3000 times a day and after six days, having mounted five times, the pupae are sealed into their cells for a further twelve days
Wasps have developed similar structural principles to the bees. With its covering removed a nest shows the layered combs hanging on a fragile network of pillars.

Frogs Inspire New Super Sticky TapeThe sticky toe pads of tree frogs , lizards and crickets have inspired Indian researchers to create a super glue and an adhesive tape that is both strong and reusable over 25 times.
Dr Animangsu Ghatak, at the Indian Institute of Technology, Kanpur, and colleagues have made an adhesive tape by running air or oil filled micro channels through a soft, elastic material, making it stickier than conventional glues.

Digital-Botanic ArchitectureDollens explores the use of software such as Xfrog to grow building elements using the software’s botanic algorithms. He designs hypothetical structures and building-skins that are realized in digital models, physical stereolithographic models, graphics and animations. For example his 2004 Spiral Bridge (influenced by a seedpod’s spiraling flight and by the biological lattice of the sponge, Euplectella).

Digital Botanic ArchitectureThe idea is not to make buildings look like botanic organisms. It is to interlace Nature and architecture enabling the design of hybridized, biological structures. The overall aim is to create new architectural typologies incorporating natural attributes ordered in performance, materials, mechanics, communications, and form.

The Lotus Effect is the self-cleaning property found with lotus plants' leaves.
Nanotechnologists are developing methods to make paints, roof tiles, fabrics and other surfaces that can stay dry and clean themselves in the same way as the lotus leaf. Usually achieved by treating the surface with a fluorochemical or silicone treatment

BioluminescenceBioluminescence is the production and emission of light by a living organism. Its name is a hybrid word, originating from the Greek bios for "living" and the Latin lumen "light". Bioluminescence is a naturally occurring form of chemiluminescence where energy is released by a chemical reaction in the form of light emission

Design biomimetics is a bridge that can connect building design professions on a route to linking designed, environmental, and, eventually, non-toxic materials. Design biomimetics can lead to technological means for visualization, digital fabrication, and, eventually, bioengineering and intelligent systems.
