In today’s rapidly urbanizing world, people are spending more time indoors and less time connected to nature. This disconnection has led to a growing recognition of the importance of integrating nature into our built environments (Browning, Ryan, & Clancy, 2014).
In architecture, this awareness has given rise to Biophilic Design, an approach that focuses on enhancing human-nature connections within our built spaces. By incorporating natural elements, Biophilic Design supports well-being, enhances productivity, and promotes sustainability (Kellert, Heerwagen, & Mador, 2008).
In this comprehensive guide, we’ll explore the core principles, benefits, and practical applications of Biophilic Design across various architectural projects, from residential homes to commercial spaces and beyond.
1. What is Biophilic Design?
Biophilic Design is an architectural design approach that seeks to connect people with nature within their built environments. The term “biophilia” was first popularized by biologist E.O. Wilson (1984), who argued that humans possess an innate affinity for nature.
Biophilic Design aims to harness this affinity by incorporating natural elements, patterns, and processes into architecture and interior design (Kellert, 2008). This approach not only enhances the aesthetic appeal of a space but also improves occupants’ physical and mental well-being (Browning et al., 2014).
Key principles of Biophilic Design include:
-
• Fostering a direct connection to nature through elements like natural light, water, and plants
-
• Encouraging indirect connections with nature through the use of organic shapes, natural materials, and biomimicry
-
• Creating spaces that facilitate human-nature interactions and stimulate the senses (Kellert et al., 2008)
2. Benefits of Biophilic Design
Incorporating Biophilic Design principles in architecture and interior design has been shown to yield numerous benefits for occupants, including the following:
Physical Health and Improved Well-being:
Exposure to natural elements can reduce stress, enhance cognitive function, promote overall mental health (Grahn & Stigsdotter, 2010), and contribute to improved cardiovascular health, reduced obesity, and enhanced immune system function (Maas et al., 2009).
Access to natural light has been linked to improved mood and reduced symptoms of depression (Beute & de Kort, 2018). Greenery and other natural elements can have a calming effect, reducing anxiety levels and promoting relaxation (Bratman, Hamilton, & Daily, 2012).
Furthermore, access to green spaces and natural light can encourage physical activity, contributing to overall health and well-being.
Increased Productivity and Psychological Well-being:
Studies have demonstrated that incorporating natural elements into workspaces can boost employee focus, creativity, and efficiency (Heerwagen, 2009).
Office workers with views of nature report higher job satisfaction, lower stress, and better cognitive function compared to those without such views (Kaplan, 1993). Workplaces with plants have been shown to increase employee productivity by up to 15% (Nieuwenhuis et al., 2014).
Biophilic Design creates spaces that promote relaxation, restoration, and mindfulness by incorporating elements like natural light, views of nature, and calming water features, contributing to a more balanced and fulfilling lifestyle.
Enhanced Sustainability and Social Cohesion
Biophilic Design often incorporates energy-efficient materials, natural ventilation, and other sustainable practices, contributing to reduced environmental impact (Browning et al., 2014).
Green roofs can help regulate building temperatures, reduce stormwater runoff, and promote biodiversity (Oberndorfer et al., 2007). Shared green spaces, such as parks, gardens, and courtyards, provide opportunities for social interaction and community engagement, contributing to overall social cohesion (Kuo et al., 1998).
Additionally, Biophilic Design elements can create a sense of place and identity, encouraging pride and attachment to one’s surroundings (Kellert, 2016).
By integrating nature into our built environments, Biophilic Design can promote stronger and more resilient communities.
3. Biophilic Design Elements and Strategies
Biophilic Design encompasses a wide range of strategies and elements to foster connections with nature. These can be grouped into three main categories: direct connections, indirect connections, and spatial configurations.
Direct Connections with Nature
-
• Natural light: Maximising daylight through windows, skylights, and light wells not only reduces reliance on artificial lighting but also has numerous health benefits, such as supporting circadian rhythms and improving mood (Figueiro & Rea, 2010; Boyce, 2014).
-
The use of daylighting strategies such as large windows, skylights, and light shelves should be prioritised to create spaces filled with natural light. Additionally, architects can consider the importance of sun orientation and shading devices to optimise light conditions throughout the day and the year.
-
• Water: Incorporating water features such as fountains, ponds, and rain gardens can provide both visual and auditory stimulation, creating a sense of tranquility and relaxation (Van Renterghem & Botteldooren, 2016).
-
The incorporation of water features such as ponds, fountains, and water walls, in designs can create soothing and restorative spaces that appeal to the senses.
-
• Plants: Integrating greenery through living walls, indoor gardens, and potted plants can improve air quality, reduce stress, and enhance cognitive function (Bringslimark, Hartig, & Patil, 2009; Nieuwenhuis et al., 2014).
-
By incorporating plants into designs in various ways, architects can aim to ensure that occupants are surrounded by nature, no matter where they are in the building.
Indirect Connections with Nature
-
• Biomimicry: Incorporating design features inspired by natural forms, patterns, and processes can evoke a sense of connection to nature (Benyus, 1997).
-
Examples include the self-cleaning properties of the lotus leaf, which has inspired the development of water-repellent materials, and the hexagonal structure of honeycombs, which can be used to create lightweight, durable building components.
-
Architects can draw inspiration from nature’s patterns and structures to inform our design choices, creating spaces that are not only visually appealing but also functional and sustainable.
-
• Organic shapes: Using non-linear, irregular shapes reminiscent of those found in nature can create a more visually interesting and engaging space (Hildebrand, 1999).
-
This might involve the use of curved walls, undulating ceilings, free-form furniture or patterns in textiles and other material finishes. By designing with this approach, architects can create spaces that are both aesthetically pleasing and in harmony with nature.
-
• Natural materials: Utilizing materials like wood, stone, and clay can provide a tactile connection to nature and contribute to a warmer, more inviting atmosphere (Dijkstra, Pieterse, & Pruyn, 2008). Architects often prioritise the use of materials such as wood, stone, and clay, selecting locally sourced and sustainably harvested options whenever possible.
Spatial Configurations
-
• Varied ceiling heights: Mimicking the varied canopy heights found in nature can create a more dynamic and engaging environment (Hildebrand, 1999). Use of this design approach can also create spaces that have a sense of depth and dimension.
-
• Transition spaces: Creating a gradual transition from indoors to outdoors through semi-enclosed spaces like courtyards, patios, and balconies can help blur the boundary between interior and exterior environments (Cooper Marcus & Sachs, 2014).
-
Designing spaces such as courtyards, terraces, and green roofs that serve as a bridge between the indoors and outdoors, offer opportunities for occupants to experience nature in a variety of settings.
-
• Prospect and refuge: Balancing open, expansive spaces with smaller, enclosed areas can offer a sense of security and exploration, satisfying our innate need for both observation and shelter (Appleton, 1975).
-
Architects strive to balance these elements, creating environments that provide a sense of security and comfort while also fostering a connection to the surrounding landscape.
