Using Biomimicry in Sustainable Design

Nature is the best learning tool. After generations and generations of improvement, nature has perfected itself to work best with its environment. Taking a closer look at an organism and the way it operates can inspire design. Janine Benyus, a biologist in the biomimicry world spoke about the innovative technologies inspired by nature: “learning about the natural world is one thing, learning from the natural world, that’s the switch.”

Biomimicry is designing technologies based upon natures’ sustainable strategies. When biomimicry is applied to design, efficiencies in energy, materials, and space are conserved. The people inventing these efficient designs range from professionals in the field, to students aiming to improve technology. In an effort to engage youth in the biomimicry community, Biomimicry 3.8 has created a competition for the best design inspired by nature.

Youth around the world have entered the challenge to design efficient technologies. The concepts in the challenge were inspired by their region-specific issues and applied natures’ efficiencies to create new technologies. Students from McGill University of Montreal, Canada addressed the problems related to cargo ships transporting organisms by inventing an air ballast system. Since cargo ships transport a lot of weight ballasting water was created to help a cargo boat stay afloat. Water is added when there is no cargo, and when there is cargo the water is released. The transfer of water to different bodies of water introduces non-region specific species. If the species is introduced to a region where it would thrive, it would become invasive and thus disrupt the ecosystem. The team from McGill proposed to replace the water with air. Filling the ballast tanks with air when the ship has cargo, and emptying the tanks when the ship is empty will replace the need for water. This design was inspired by the cuttlefishes’ ability to control buoyancy. Another team in Yucatan, Mexico designed a stable form of transportation. The alternative before this design was working tricycles which were unstable and inefficient. After study snakes movements, the team designed a quadricycle that operates via hand steering movements. At the Institute for the Built Environment (IBE) we strive to create efficiencies in construction to preserve the beauty of this planet. By using the U.S. Green Building Council rating system, IBE applies biomimicry technologies to construction projects. With construction comes options for implementation of new technologies. Everywhere you look in nature you can see efficiencies that have been improved over generations and generations. Some of the greatest inventions have been inspired by nature.
