Architectural innovations that are responsive to architecture do not have to resemble a plant or an animal. Where form is intrinsic to an organism’s function, then a building modeled on a life form’s processes may end up looking like the organism too. Architecture can emulate natural forms, functions and processes. Though a contemporary concept in a technological age, biomimicry does not entail the incorporation of complex technology in architecture. In response to prior architectural movements biomimetic architecture strives to move towards radical increases in resource efficiency, work in a closed loop model rather than linear (work in a closed cycle that does not need a constant intake of resources to function), and rely on solar energy instead of fossil fuels. The design approach can either work from design to nature or from nature to design. Design to nature means identifying a design problem and finding a parallel problem in nature for a solution. An example of this is the DaimlerChrysler bionic car that looked to the boxfish to build an aerodynamic body.[10] The nature to design method is a solution-driven biologically inspired design. Designers start with a specific biological solution in mind and apply it to design. An example of this is Sto’s Lotusan paint, which is self-cleaning, an idea presented by the lotus flower, which emerges clean from swampy waters.
