BIOPHILIC DESIGN: Creating Green Buildings for Life (Part 2)
PART 2: Exploring Human Experiences with Nature
In our increasingly urbanized and technology-driven world, people are spending more time indoors than ever before. While modern buildings may be efficient and functional, they often disconnect us from the natural world—something our bodies and minds still crave. This is where Biophilic Design comes into play.
OBJECTIVE
This is the second episode of our mini-series on the subject of Biophilic Design. So, perhaps you may want to go through with the first part for a better understanding:
BIOPHILIC DESIGN: Creating Green Buildings for Life (Part 1)
Biophilic Design goes beyond simply adding plants to a space; it is an evidence-based approach to architecture and interior design that fosters a deeper human connection to nature. It taps into our innate biological affinity for the natural environment, improving physical health, boosting mental well-being, and enhancing productivity. By integrating natural elements, patterns, and spatial experiences into the built environment, biophilic design transforms ordinary spaces into restorative and inspiring places to live, work, and learn. In this episode, it will be a different approach this time. Instead of extracting excerpts from reference materials, I will be combining my personal insights and experiences while referencing research material. So please remain seated, as this would be another adventurous expedition in the enchanting jungles of Amazon.
THREE KEY CATEGORIES OF BIOPHILIC DESIGN
To better understand this concept, biophilic design can be explored through three key categories of human experiences with nature: Direct, Indirect, and Experience of Space & Place. Each category offers unique ways to incorporate the benefits of nature into our everyday lives.
1. Direct Experiences of Nature
Direct experiences involve actual, physical interaction with natural elements. These appeal to our senses in real time, allowing us to see, hear, feel, and even smell nature.
Natural light is one of the most effective ways to connect people with nature indoors. Sunlight regulates our circadian rhythm, boosts mood, and can enhance focus and creativity. Light plays a crucial role in helping people orient themselves with the time of day and the season. It contributes to wayfinding and comfort, and it can create natural patterns, movements, and shadows.
In design, this concept can be applied creating buildings with strategically placed windows, skylights, clerestories, reflective materials, light wells and atriums allow natural daylight to fill the space, reducing the need for artificial lighting and creating a healthier environment. Imagine working in an office bathed in soft morning light; your energy levels rise naturally, and your day begins on a brighter note.
Example: An office building with a glass façade and strategically placed workstations to maximize daylight exposure.

b. Fresh Air & Natural Ventilation
Breathing in fresh air can truly rejuvenate both our minds and bodies. Features like cross-ventilation, operable windows, and open layouts allow breezes to bring in the scents of flowers, rain, and nearby vegetation. These conditions can be managed using windows and other passive strategies. Most importantly, variations in these elements can enhance occupant comfort and productivity. This experience is not only enjoyable but also healthier, as it helps reduce indoor pollutants and increases oxygen levels.
Example: A home designed with sliding glass doors that open to a garden, letting in breezes and scents from nearby plants.

c. Water Features
Water has a uniquely calming effect. The sight and sound of flowing water can lower heart rates, reduce stress, and create a meditative atmosphere. Water engages multiple senses and can be effectively integrated into building design to enhance movement, sound, touch, and sight. Whether it’s a trickling indoor fountain or a koi pond in a courtyard, water attracts people and encourages them to take a moment to pause. Water can be incorporated in buildings through elements such as water bodies, fountains, wetlands, and aquariums. People have a deep connection to water, and when utilized in design, it can reduce stress and improve health, performance, and overall satisfaction.
Example: I had my own personal experience in Japan going to Onsen. They have a section where you can lie down in flowing streams of natural warm water that provides relaxing atmosphere and a calming effect to the mind and body.
d. Vegetation & Greenery
Plants do not only look beautiful; they also improve air quality, reduce noise, and enliven spaces. Engaging with leaves, smelling flowers, or tending to indoor gardens provides sensory experiences and relaxation. Incorporating vegetation into both the exterior and interior spaces of a building creates a direct connection to nature. It is important to have an abundance of plants, such as green walls or numerous potted plants, some of which should produce flowers. Plants can enhance physical health, improve performance and productivity, and reduce stress for the occupants of the building.
Example: A roof terrace surrounded with plants and trees. Some call these roof gardens or green roofs. (See cover image)
e. Seasonal Changes
Observing the changing colors of trees, the blooming of flowers, or the falling of rain helps us appreciate nature's cycles and our role within them. Weather can be directly observed through windows and transitional spaces, but it can also be simulated by manipulating the air within a space. Incorporating large windows or outdoor seating areas that offer seasonal views establishes a dynamic connection with the environment, ensuring that our spaces remain visually and emotionally engaging throughout the year. In ancient times, awareness of the weather was crucial for human survival and fitness. Today, it continues to promote awareness and mental stimulation.
Example: A classroom with large windows overlooking deciduous trees that change colors throughout the year. Another example I could share may not only be visual, but something heard as well such as falling raindrops. Its sound always gives me a unique soothing effect. Same thing also when looking at them falling on your window sills.
ABSTRACT: Given the broad nature of this category, I have selected only a few important items for discussion. When it comes to incorporating nature in Biophilic design process, some elements were found to be challenging to achieve. However, I will leave room for their evolution over the years and will address them when the time is right. These elements include animals, natural landscapes, and fire, and there may be additional categories that develop in the future.
2. Indirect Experiences of Nature
Indirect experiences are symbolic or representational. They evoke nature without direct physical presence, often through design, material choice, and imagery.
a. Natural Materials
Materials like wood, bamboo, stone, and clay connect us to the earth’s raw textures and patterns. They invite touch, carry natural scents, and age gracefully over time. For example, a timber staircase not only serves its function but tells a story through its grain.
People are increasingly drawn to natural materials because they engage the mind and elevate our surroundings. These materials age beautifully, developing a unique patina that resonates with us on an emotional level. In architecture, incorporating elements like wood, bamboo, stone, and clay connect us to the earth’s raw textures and patterns and creates structures that feel alive and environmentally friendly. For example, a timber staircase not only serves its function but tells a story through its grain.
Similarly, in interior design, using natural fabrics and furnishings adds warmth and authenticity to our spaces. While leather has traditionally been viewed as a staple biophilic material, awareness of its environmental impact—stemming from animal agriculture as a significant contributor to climate change—compels us to reconsider our choices. Alternatives such as faux leathers made from mushrooms, pineapple skin, or cactus not only offer sustainability but also align with our desire for a deeper connection with nature. Embracing these plant-based options reinforces the philosophy of biophilia, reminding us that fostering a bond with nature shouldn’t come at the cost of harming it.
Example: A spa with wooden floors, stone basins, and woven rattan furniture.
b. Nature-Inspired Patterns (Biomorphic Forms)
Nature’s forms inspire remarkable designs because they are rarely straight or uniform; they create curve, spiral, and captivating patterns. By mimicking these shapes in furniture, textiles, and architectural details, we can evoke a sense of familiarity and comfort in our environments.
Incorporating repetitive and varied patterns found in nature, like fractals, into facades or structural elements can transform a space. These natural geometries feature hierarchical organization and flowing lines, moving away from rigid straight edges and harsh angles. Think of the honeycomb pattern or the gentle ripples in water—these designs not only enhance aesthetics but also connect us to the beauty of the natural world.
Example: Ceiling panels shaped like overlapping petals or wall tiles with ripple patterns.
c. Images & Artwork of Nature
Even without a window view, captivating images of forests, mountains, or ocean waves have the power to significantly reduce stress and enhance mood. In settings like hospitals or underground workspaces, these visuals become vital emotional lifelines for occupants. Numerous studies demonstrate that exposure to nature imagery provides profound emotional and intellectual satisfaction. By integrating these inspiring depictions through paintings, photographs, sculptures, murals, or videos, we can create environments that promote well-being and resilience.
Example: A hospital waiting room decorated with large, high-resolution images of forests and waterfalls.

d. Natural Colors
Colors significantly influence our mood, and the hues derived from nature—like soothing greens, tranquil blues, warm browns, and soft earth tones—instill a sense of calm and balance in any environment. Imagine how a green-accented wall can enliven a room, reminiscent of the refreshing ambiance of a sunny park. Earth tones, often muted shades of brown, green, and blue, are prevalent in nature and should be the go-to choices for building colors. These natural hues create a harmonious atmosphere. Brighter colors, while eye-catching, should be used with caution; research has shown that red flowers on plants can become overwhelming and distracting for those who occupy the space. Embracing these subtle shades can transform your environment into a serene sanctuary.
Example: An apartment with soft green walls, sandy beige flooring, and warm wooden cabinetry.
e. Simulation of Natural Light & Shadows; and Air
When natural light is unavailable, utilizing lighting systems that replicate daylight cycles is essential for maintaining our body’s rhythm. By incorporating soft shadows and dynamic lighting changes throughout the day, we can evoke the feeling of sunlight filtering through leaves, creating a more harmonious environment. In settings where natural ventilation and light cannot be achieved, innovative strategies for interior lighting and mechanical ventilation can effectively mimic these vital elements. Designers can enhance this experience by using a variety of lighting types, reflective surfaces, and natural forms that allow light to diffuse beautifully. Additionally, subtle alterations in temperature, humidity, and air velocity can create the sensation of natural airflow, making our spaces feel more alive and connected to nature.
Example: LED systems in offices that shift from cool white in the morning to warm amber in the evening.
3. Experience of Space & Place
This category focuses on how spatial arrangements and environmental cues mimic the way we experience landscapes in the wild, influencing comfort, safety, and curiosity.
a. Prospect & Refuge
Humans feel secure when they can see their surroundings from a vantage point. This is why we gravitate toward high terraces or rooms with wide panoramic views—it’s a natural survival instinct rooted in open plains. Prospect emphasizes horizons, movement, and sources of danger.
Refuge refers to the building's ability to provide comfortable and nurturing interiors (alcoves, dimmer lighting). Conversely, we also need places of retreat. Small alcoves, covered porches, and enclosed nooks provide comfort, privacy, and a sense of protection—much like sheltering under a tree.
Examples: Design elements that include balconies, alcoves, lighting changes, and areas spaciousness (savannah environment).
b. Mobility
The ability for people to comfortably move between spaces, even when complex; it provides the feeling of security for occupants and can be done through making clear points of entry and egress. When different parts comprise a whole, it provides satisfaction for occupants
Example: Design elements include interior spaces using clear boundaries and or the integration of a central focal point.
c. Mystery
Spaces that suggest there’s more to discover encourage curiosity and exploration. When a path disappears behind a bend or a curtain partially reveals what’s beyond, our curiosity draws us forward. This sense of mystery adds depth and engagement to spaces.
Example:
A winding garden path partially obscured by hedges, inviting people
to find out what’s around the corner.
d. Risk / Peril (Perceived)
Small doses of perceived danger—like standing on a glass floor high above ground—create excitement and heighten sensory awareness, making the space more memorable.
Example: A glass skywalk over a canyon or a rooftop pool with a transparent edge.
e. Transitional Spaces
This element aims to connect interior spaces with the outside or create comfort by providing access from one space to another environment through the use of porches, decks, atriums, doors, bridges, fenestrations, and foyers. This concept creates a gradual sensory shift. This transition makes the experience richer and more comfortable.
Example: A covered veranda with potted plants that leads into an open garden.
f. Integration with Local Context - Cultural and Ecological Attachment to Place
Using local materials, referencing traditional architecture, and designing in harmony with native landscapes connect people not just to nature but to culture and place. Creating a cultural sense of place in the built environment creates human connection and identity. This is done by incorporating the area's geography and history into the design. Ecological identity is done through the creation of ecosystems that promote the use of native flora and fauna.
Example: Log houses or nipa huts using native wood, bamboo, natural materials like nipa roofing, walls with traditional weaving techniques, and landscaping with endemic plants.
FINAL THOUGHTS
Biophilic design is far more than a fleeting architectural trend; it is a vital response to our inherent need for nature. Our bodies and minds are essentially wired to connect with the natural world, and when our built environments reflect this bond, we truly thrive. By intentionally integrating direct and indirect experiences of nature, alongside spatial features that resonate with the outdoors, we can craft spaces that enhance health, ignite creativity, and promote overall well-being. In today’s world, where disconnection from nature is prevalent, biophilic design emphasizes that the most effective buildings do more than provide shelter—they rejuvenate our spirits and remind us of what it means to be alive.
