Sustainable Design and Biomimetics

  1. 1. SUSTAINABLE DESIGN AND BIOMIMETICS ABHILASHA TRIPATHI M.Tech Env. Engg. and Mgmt. CPEE, P.U.
  2. 2. SUSTAINABLE DESIGN • Objective: To eliminate negative environmental impact completely through skilful, sensitive design. Keeping in mind that it don’t affect the availability of resources for future generations. • Chair grown by tree shaper John Krubsack in Wisconsin, United States in 1919.
  3. 3. SUSTAINABLE DESIGN PRINCIPLE Low-impact materials Energy efficiency Emotionally durable design Sustainable design standards Design for reuse and recycling Bio mimicry Service substitution Renewability
  4. 4. BEES (Building for Environmental and Economic Sustainability) software • A powerful technique for selecting cost- effective, environmentally- preferable building products. • Developed by the NIST (National Institute of Standards and Technology) Engineering Laboratory the tool is based on consensus standards and designed to be practical, flexible, and transparent. • BEES Online, aimed at designers, builders, and product manufacturers, includes actual environmental and economic performance data for 230 building products.
  5. 5. BEES cont.… LIFE CYCLE ANALYSIS • Analyse the performance of building products by using the life-cycle assessment approach specified in the ISO 14040 series of standards. • All stages in the life of a product are analysed: • Raw material acquisition • Manufacture • Transportation • Installation • Use • Recycling • Waste management
  6. 6. Economic performance is measured using the ASTM(American Society for Testing and Materials) standard life-cycle cost method, which covers the costs of initial investment, replacement, operation, maintenance and repair, and disposal. Environmental and economic performance are combined into an overall performance measure using the ASTM standard for Multi-Attribute Decision Analysis For the entire BEES analysis, building products are defined and classified according to the ASTM standard classification for building elements known as UNIFORMAT II (a standard for specifications, cost estimation and cost analysis in USA and Canada).

  8. 8. LOOP AND HOOK FASTNER • Swiss engineer George de Mestral invented the amazingly useful fastening material called VELCRO after seeing how cockleburs from the burdock plant stuck like glue to the fur of his dog. • Based upon that he came up with the Velcro. • Also called “hook and loop fastener” or “touch fastener” as “Velcro” .
  9. 9. RELAX YOUR WASHING MACHINES, CLOTHES CAN CLEAN THEMSELVES TOO • The leaves of Lotus are coated with nanoscopically tiny bumps and the bumps are, themselves, covered with a thin layer of wax. • Dirt particles balance precariously on the waxy bumps but never get a really good grip on the main surface of the leaves below. • The nano-bumps work a bit like a natural detergent, holding dirt clear of the leaves so water can easily wash it away.
  10. 10. • So, Now clothing manufacturers are coating garments like skate pants with nanofibers so they work in a similar way. • The idea is that dirt is held slightly apart from the main fabric so stains cannot penetrate deeply; clothes coated with nanofibers can be washed clean much more easily.
  11. 11. DIVING COSTUMES MIMICING SHARKS • Human skin is not designed for swimming • Water doesn't flow well past human skin because the skin starts to wrinkle. • For hairy body, every single one of your hairs will drag and slow you down even more.
  12. 12. • To avoid the problem a swimsuit is manufactured by Speedo company to mimic a shark's skin. • FASTSKIN, the tight-fitting suit covered with tiny v-shaped channels, just like the ridges (technically known as placoid scales or dermal denticles) on a shark's body. • The idea is that water whizzes along these channels, reducing drag and turbulence, so you can swim faster. • Fits tightly thus, compressing the swimmer's muscles, helps to reduce fatigue. • According to Speedo, swimsuits like this can boost a swimmer's speed by up to 3 percent.
  13. 13. HEY!! DRESS UP LIKE A PINECONE • If it's going to rain, the spines close up to protect the seeds inside. • If it's going to stay dry, the spines open up to improve the chances of the seeds escaping.
  14. 14. •The London College of Fashion are trying to design biomimetic clothes that could work the same way. •The fabric could be made with an outer layer of tiny spikes, only 1/200th of a millimetre wide. •When it's hot, the spikes would open up to let out the heat, cooling you down. •When it's cold, the spikes would flatten back down to trap air and provide more effective insulation.
  15. 15. BETTER LEARN DRIVING FROM THEM….. • 80 million of them in a kilometre square and yet they never collide. • Collision avoidance circuitry is under research, For this the neuron of locust is under study. • They have a distinctive way of processing information through electrical and chemical signals, giving them an extremely fast and accurate warning system for impending collisions. • Robotics is also in adopting the technique.
  16. 16. FLIGHT OF FREEDOM….. • A German engineer called Otto Lilienthal strapped wings to his arms and jumped off a hill in an attempt to fly. • Though eventually, kill himself trying to fly like the birds. • But his pioneering glider experiments inspired the Wright brothers to develop their engine- powered airplanes in the early 20th century.
