Biomimicry in Architecture: Learning Design Lessons from Nature
1. Introduction: Nature as Mentor
For the past 3.8 billion years, life on Earth has been engaged in a relentless process of research and development. Through the slow, rigorous, and unforgiving filter of natural selection, it has discovered what works, what is appropriate, and what lasts. Nature is the world’s most accomplished architect and engineer, having already solved the very challenges we are now struggling with: how to generate energy, manage water, create durable structures, and build resilient systems, all while using a limited palette of materials and creating zero waste. A profound and exciting design discipline has emerged from this realization, known as biomimicry. 🍃
Coined and popularized by scientist and author Janine Benyus, biomimicry is the conscious emulation of nature’s forms, processes, and ecosystems to solve human problems. In architecture, this goes far beyond simply making a building look like a shell or a flower (a practice known as biomorphism). Biomimicry is a deep, functional design methodology that seeks to understand the performance of natural systems. It asks not “What can we extract from nature?” but “What can we learn from it?” By studying a termite mound’s self-cooling abilities or a sea sponge’s structural integrity, architects can uncover elegant, time-tested solutions to create buildings that are dramatically more efficient, resilient, and sustainable.
2. The Three Levels of Biomimicry
Biomimicry operates at three distinct but interconnected levels of complexity, moving from mimicking a single organism to emulating an entire ecosystem.
- 1. Emulating Form (The Organism Level):
This is the most direct and easily understood level of biomimicry. It involves mimicking the specific shape, structure, or form of an organism to achieve a particular function. It is a process of learning from nature’s morphology.
- Example: The Gherkin and the Sea Sponge. London’s iconic Gherkin tower (30 St Mary Axe), designed by Foster + Partners, features a distinctive spiraling diagrid structure. This design was partly inspired by the Venus Flower Basket, a deep-sea sponge whose cylindrical, lattice-like exoskeleton is incredibly strong and stiff, allowing it to withstand powerful ocean currents. By emulating this highly efficient structural form, the architects were able to create a building that is exceptionally rigid while using significantly less steel than a conventional skyscraper with a traditional frame.
- 2. Emulating Process (The Behavior Level):
This deeper level of biomimicry involves copying a natural process, behavior, or method of making something. It is about understanding how an organism achieves a certain effect, such as self-healing, self-cleaning, or passive cooling.
- Example: The Lotus Effect. The lotus leaf is renowned for its ability to stay clean in muddy waters. Microscopically, its surface is covered in tiny, waxy bumps that cause water to bead up into perfect spheres. As these beads roll off the leaf, they pick up and carry away dirt particles. This “Lotus Effect” has been emulated to create a new generation of superhydrophobic materials, including self-cleaning paints, coatings, and glass. A building coated with this material can be cleaned by a simple rain shower, reducing maintenance costs and the use of harsh chemical detergents.
- 3. Emulating System (The Ecosystem Level):
This is the most holistic and ambitious level of biomimicry. It involves designing a building, a campus, or even an entire city to function like a complete ecosystem, such as a forest or a prairie.
-
Principles of an Ecosystem: Mature ecosystems run on sunlight, use only the energy they need, fit form to function, recycle everything, and reward cooperation. There is no concept of “waste” the waste output of one organism is the resource input for another.
-
Example: Circular and Regenerative Design. An ecosystem-level biomimetic building would function like a living system. It would harvest its own water (like a bromeliad), generate all its own energy from the sun (like a leaf), be constructed from local, recycled materials, and treat its own waste, perhaps turning it into nutrients for a rooftop garden. This is the core idea behind the “Living Building Challenge” and the broader movement towards a circular economy, where our built environments are designed to be fully integrated, self-sustaining, and regenerative.
3. The Methodologies: How to Ask Nature for Advice
There are two primary pathways for applying biomimicry in the design process.
-
Design to Biology: This approach begins with a specific human design challenge. The designer identifies the core function they are trying to achieve (e.g., “How can we design a quieter train?”) and then turns to the natural world to ask, “How has nature already solved this problem?” This was the process that led to the redesign of the Japanese Shinkansen bullet train. The train was creating a loud sonic boom when exiting tunnels. The engineering team looked to the kingfisher, a bird that can dive from the air into water with almost no splash. By modeling the train’s nose cone on the precise shape of the kingfisher’s beak, they not only solved the sonic boom problem but also made the train 15% faster and 10% more energy-efficient.
-
Biology to Design: This process begins with a biological discovery. A biologist or an observer in nature identifies a fascinating adaptation or principle (e.g., the way a beetle in the Namib desert harvests water from fog on its back). The designer then takes this biological insight and asks, “What human design challenges could this help us solve?” This is a more exploratory process, creating a library of natural solutions waiting for the right problem to emerge.
4. Case Studies in Biomimetic Architecture
-
The Eastgate Centre, Harare, Zimbabwe (Mick Pearce, 1996): This shopping center and office block is a world-renowned example of mimicking process. Located in a climate that would typically require massive air-conditioning, the building maintains a comfortable interior temperature year-round using virtually no energy for cooling. Architect Mick Pearce modeled the building’s passive ventilation system on the self-cooling mounds of African termites. The building uses its high thermal mass to absorb heat during the day. At night, a system of fans draws in cool night air, which flushes the building and cools the concrete structure. During the day, warm air rises and is exhausted through a central atrium and a series of thermal chimneys, creating a continuous convection current—precisely the same strategy used by the termites.
-
Esplanade – Theatres on the Bay, Singapore (DP Architects & Michael Wilford, 2002): Nicknamed “the durian” by locals due to its spiky appearance, the twin domes of this performing arts center are a brilliant example of climate-specific biomimicry. The challenge was to create a glass enclosure that would provide views out but not allow the intense tropical sun to create an unbearable greenhouse effect. The solution was a sophisticated sun-shading system composed of over 7,000 triangular aluminum louvers. The size and angle of each louver were precisely calculated by computer models based on its specific orientation to the sun’s path throughout the year. The system functions like a protective, directional skin, mimicking the way shells and fruit husks (like that of the durian) are often optimized to provide protection from the sun while allowing for a degree of filtered light and air.
5. Biomimicry vs. Other Green Design Approaches
It is important to distinguish biomimicry from other related concepts.
-
Biomorphism vs. Biomimicry: Biomorphism is the practice of making buildings look like natural forms. The Sydney Opera House looks like shells, and TWA Flight Center looks like a bird, but they do not function like shells or birds. This is about aesthetic imitation. Biomimicry, in contrast, is about functional and systemic imitation.
-
Biophilia vs. Biomimicry: Biophilia is the idea that humans have an innate need to connect with nature. Biophilic design addresses this by incorporating natural elements into a space—plants, water, natural materials, views of nature—to improve human health and well-being. Biomimicry is about learning from nature as a source of engineering and design solutions. The two concepts are highly complementary and should ideally be used together.
6. Conclusion: Nature as Model, Measure, and Mentor
Biomimicry represents a fundamental and necessary shift in our worldview. It is a move away from the industrial-age mindset of nature as a warehouse of resources to be exploited, and towards a new mindset of nature as a library of brilliant, time-tested ideas to be consulted. Janine Benyus refers to nature as “model, measure, and mentor.” It is a model for our designs, a measure against which we can judge the sustainability of our innovations, and a mentor that teaches us a more resilient and integrated way of living on this planet. By humbly asking the question, “How would nature solve this?”, architects and designers can begin to create a built environment that is not just less bad, but is actively good—an architecture that is not just sustainable, but truly regenerative.
