Introduction
Picture yourself walking into a structure where the walls are alive, light is not a luxury but a necessity, and nature is not an ornament but a necessity. This is the world of biophilic architecture, where nature and contemporary design are intertwined. With the increase in the size and population density of cities, people’s interaction with nature is limited. However, the inherent need of people to be in touch with nature is still present. This desire has led to the emergence of a new architectural movement – biophilic design, which aims to bring nature into the built environment.
In this blog, we discuss what biophilic architecture is, how it affects well-being and the sustainability advantages of the concept, as well as some interesting case studies from around the world.
What is Biophilic Architecture?
In it's essence, biophilic architecture is based on biophilia, a concept that was coined by biologist Edward O. Wilson in the 1980s and translates to love of life or living systems. The idea postulates that people have a fundamental psychological need to be in contact with nature. Biophilic architecture, therefore, uses light, air, plants and water in the design of buildings to facilitate this link. But it is not just a visual solution – biophilic design also incorporates haptic and auditory stimuli, as well as olfactory stimuli to create the sensation of being in nature.
1. Key Principles of Biophilic Design
Natural Light and Ventilation: The use of natural light and air in buildings not only saves energy but also improves the mood and performance of the people inside the building.
Integration of Natural Elements: Indoor plants, water fountains and the incorporation of natural elements such as wood and stone give a feeling of harmony.
Connection with the Outdoors: The use of large windows, skylights and open floor plans ensures that the occupants have a clear view of the outside environment, thus making them feel closer to nature.
Non-Rhythmic Sensory Stimuli: The use of stimuli that are unpredictable but positive such as the sound of leaves or smell of flowers enriches the sensory input.
Ecosystem Imitation: Some designs try to replicate whole ecosystems, for instance, designing buildings that have indoor trees or vertical gardens that mimic the natural environment.
2. The Psychological and Physical Benefits of Biophilic Architecture
Apart from the visual aspect, biophilic architecture has many psychological and physiological advantages. It has been found that exposure to natural elements can help to decrease stress levels, enhance creativity and boost cognitive performance.
3. Mental Health and Well-being
The contemporary world isolates people from nature, and this is why Richard Louv has introduced the term called nature-deficit disorder. Staying for long hours in artificial environments such as cities leads to anxiety, depression and fatigue. Biophilic design solves this by bringing nature back into our lives, thus enhancing our psychological health. For example, research has shown that patients in hospitals that have windows with views of nature heal faster and employees in biophilic environments are happier and less stressed.
4. Improved Productivity
Introducing natural elements into the workplace can also result in improved efficiency. According to a study conducted by Human Spaces, workers who are exposed to natural features such as plants and light had a 15% improvement in their well-being and a 6% improvement in productivity. The biophilic elements assist in combating mental fatigue, enhance focus and create a more relaxed yet invigorated workplace.
5. Enhanced Physical Health
Biophilic architecture can also have a positive effect on physical health. Natural lighting helps to minimize the use of artificial lighting which is known to cause sleeplessness and eye problems. Properly designed ventilation systems provide fresh air to the indoor environment and minimize the transmission of airborne diseases and poor air quality. The use of natural materials such as wood also helps to improve the quality of air inside the house since they do not contain volatile chemicals as found in synthetic materials.
6. Sustainability and Environmental Impact
However, the environmental benefits of biophilic design are just as persuasive as the human ones. With the increasing effects of climate change, biophilic architecture offers a chance to design structures that are more efficient in terms of energy use.
7. Energy Efficiency
Another of the key concepts of biophilic design is the use of natural light and air, which saves energy. The use of biophilic features in buildings can reduce energy requirements by as much as half, which in turn reduces the carbon impact of the building. Some of the sustainable practices that architects use in biophilic designs include green roofs, vertical gardens and passive solar design. These elements not only help in saving energy but also assist in improving the insulation and heat control of the building.
8. Biodiversity and Urban Greening
Biophilic architecture can also assist cities to reduce the effects of the urban heat island, a phenomenon where urban areas are much hotter than the surrounding rural areas because of human activities. Green roofs and walls reflect solar radiation, dissipate heat through evapotranspiration and support bird and insect life, enhancing biological richness in cities. In cities such as Singapore, which is known as the “city in a garden”, biophilic architecture is a significant part of the city’s green infrastructure, with many buildings featuring impressive living walls that clean the air and support local fauna.
9. Water Management
Indoor waterfalls and ponds are used in biophilic buildings as part of the sensory stimulation, but they also serve practical purposes. These features can assist in the control of stormwater, thus easing the pressure on the urban drainage networks. Some of the biophilic designs also include rainwater harvesting systems to recycle water making the building even more sustainable.
10. Iconic Examples of Biophilic Architecture
In the contemporary world, architects are embracing biophilic design to develop structures that are unique and represent the natural environment.
The Bosco Verticale, Milan, Italy
The most famous example of biophilic design is the Bosco Verticale (Vertical Forest) in Milan. These residential towers are clad in over 20,000 trees and plants that help to reduce CO2, release oxygen, and act as an insulator. Not only do these towers save energy costs but also they provide habitat for birds and insects in the urban setting.
The Eden Project, Cornwall, UK
The Eden Project is situated in Cornwall and is a perfect example of how architecture can mimic ecosystems. The complex is designed to have large biomes containing various climates including tropical rainforest, Mediterranean and others, all enclosed in large geodesic domes. The Eden Project is an educational facility and an example of biophilic design that helps people remember that we are part of nature.
Singapore's Changi Airport
Changi Airport’s Jewel, a biodome, has the world’s largest indoor waterfall and a forest within an airport environment, and it is one of the busiest airports globally. The airport has over 2000 trees and plants and this makes the environment to be more attractive and also makes the journey to be more enjoyable.
The Future of Architecture: A Symbiosis with Nature
Biophilic architecture is not a trend, but a transition to a new level of sustainable, humane and nature-oriented construction. With the increase in the rate of urbanization, architects are in a position to design buildings that are not only utilitarian but also those that feed the soul and the earth. Biophilic design reimagines the way we interact with the built environment and makes buildings into living organisms that are part of the biosphere. In the future, biophilic architecture is a chance to design cities as spaces for living and working, but also as spaces where people and nature can coexist. It is a vision of the modernity that is in harmony with the eternal values of the nature and the architecture that does not just contain life but enhances it. Biophilic architecture is a fresh concept in a world that is gradually being filled with concrete jungles, it is a concept that tells us that nature is not just a place to visit but a companion to live with.
