Will the real biomimicry please stand up?


            When you throw something away, where is away?  Is there somewhere that magically eradicates trash and debris?  If you're a plant, you have a system that takes care of that in an amazing way.  Nature does things so differently than humans do.  If a human wanted to make a leaf, he would take some green material and cut out a leaf, then throw away the left over material.  Nature makes the leaf exactly the size that is necessary.  There is no waste in nature.  When a tree drops its leaves in the fall, those leaves become soil for the next year.  If humans could learn from nature and design with a sort of ecosystem-like pattern, the world would be a different place and we would be practicing biomimicry.
            There has been a lot of organic design going on lately, but this is copying the geometry of nature, not biomimicry.  Biomimicry has nothing to do with appearance.  The definition of biomimicry is imitating or becoming inspired by nature's forms and processes in order to solve human problems.   The other way that nature has influenced design is through bio-utilization.  This is using nature to solve a design problem, like using mushrooms in leeching fields where a septic tank drains waste.  This bio-utilization is helpful, but should not be mistaken for biomimicry. 
            To begin the process of biomimicry, the designer must first research and examine an organism or ecosystem.  Next, should come a thoughtful execution of the design principles found in nature's solution.  At this point we are learning from nature, not about nature.    We must always ask ourselves how nature would deal with an issue, then use biology as a tool for solving this problem or achieving a function. 
            There are two ways designers address the use of biomimicry in design.  One is the problem-based approach.  In this approach, the designer works with a biologist after defining the problem.  They reframe the problem, find a biological solution, extract the biological solution and apply it in the design.  The second approach begins at the solution.  Once a biologist finds a solution, he must collaborate with a designer to see if it can be used as a relevant design consideration.  When biological research influences our design, the collaborative process depends on the collaborators having relevant research, not on a particular design problem.
            An example of problem-based biomimicry usage comes from a product called Smart Paints.  These paints use a self-cleaning technique learned from lotus leaves. The paint surface has densely packed ridges like the bumps on lotus leaves.   These little bumps prevent water drops from diffusing.  They roll off the surface taking any dirt and debris with them.
            Similarly, biologists were inspired by the way that conifer cones protect their seeds.  This is a solution-based innovation.  The spines close to keep the seeds dry on a rainy day and open up to let the seeds go during dry weather.  The FAZ Pavillion, located in Frankfurt, Germany, is an example of biomimicry, which uses the conifer cone for its design.  Like the conifer cone, the pavillion responds to weather changes based on a simple material element, which has an embedded sensor, no-energy motor and regulating element.  The pavillion's surface is fully open on sunny days.  When it rains, the humidity triggers a rapid, autonomous response, closing the structure to form a weatherproof skin.
            These case studies encourage us to include biologists early and fully in the design process.  They should not be "add-ons" in this process.  We can accomplish a great deal more when working with scientists as a team, fully engaged in collaboration from the very start of a project.
            Some biologists and designers believe that our future interior spaces; where we work, live and play, may be designed to function like living organisms.  It is hoped that we will learn to use the surrounding nature to provide our energy and water.  The author of this article hopes that in the future, architects and designers will be inspired by nature instead of machinery.
