Biophilic Design Defined
Biophilia is a relatively obscure term for a basic principle – humans are instinctively drawn to nature; it nurtures, calms and inspires us. Our design concepts for all types of senior living housing and care residences incorporate biophilic design elements to positively impact health and well-being.
German social psychologist Erich Fromm coined the term in 1964 to describe our innate need to be connected to nature. E.O. Wilson, American biologist, researcher, theorist, naturalist and author of the book “Biophilia,” came up with the biophilia hypothesis—that the deep affiliations humans have with other life forms and nature as a whole are rooted in our biology.

The Research Behind Biophilic Design
For most of us, the choices above seem obvious. However, these choices go beyond personal preference. A significant body of research has established that connections to nature, both direct and simulated, promote health, well-being, learning and productivity.
In 1984, Roger Ulrich and his team demonstrated that patients recovering from gallbladder surgery at a suburban Pennsylvania hospital had different experiences based on the views outside their windows. Those fortunate to end up in rooms with views to a small stand of deciduous trees requested less pain medications, had fewer negative comments from nurses’ charting observations (e.g. upset and crying) and were discharged earlier than patients who, after their surgeries, ended up in rooms facing a brick wall.
More recently, a 2014 Cornell University study demonstrated that hospital nurses who had access to natural light experienced significantly lower blood pressure, communicated with colleagues more frequently, and served their patients in better moods than nurses who settled for large doses of artificial light.
Gadsden Glen Health & Rehabilitation Center
Outdoor connections are a priority for senior care environments like the below examples from Bishop Gadsden in Charleston, South Carolina. Biophilic design principles guided the design vision. Views to nature were a design focus, along with integrating local vernacular and curating “light and bright” spaces to uplift and inspire all who live, work, and visit.
And it’s not just healthcare environments where connections to nature can have a measurable impact. In office settings, studies have shown not only reduced absenteeism for employees with views of nature, but also increased productivity.
Courtyard at RLPS
The courtyard area at the center of our own office building helps to maximize daylight and outdoor connections for all employees. Operable screen doors on every side provide cross ventilation and bring in the smells and sounds of nature.
In a perfect world, we would all spend significant time outdoors in nature, perhaps even partaking in the Japanese practice of forest bathing. This utopia would extend to the buildings where we would live, work and play with abundant, multi-sensory nature connections in all areas.
This is the ultimate goal, but the reality is that most of us spend less than ten percent of our time outdoors and many of our interior environments provide little or no connection to the natural world. This reality makes biophilic design principles that much more important.
It’s the reason our team strives to incorporate these values into every project to the greatest extent possible. Based on the book Biophilic Design: The Theory, Science and Practice of Bringing Buildings to Life, Stephen Kellert presents the following six key elements of biophilic design.
1. Environmental Features
This straightforward category involves incorporating well-recognizing characteristics of the natural world into the built environment. A few examples would include color, water, fire, sunlight, plants, animals, natural materials, façade greening, habitats and eco-systems.

2. Natural Shapes and Forms
Beyond the “real deal,” there are also benefits to incorporating representations or simulations of the natural world. Another study by Roger Ulrich demonstrated that patients in a recovery suite following surgery responded positively to a simulated nature scene on the wall over a plain white wall or abstract artwork, with the latter actually eliciting negative responses.
Artwork selections, especially in senior care residences, often feature beautiful nature scenes and botanicals. In a 2008 study in the Journal of Environment and Behavior, a University of Michigan researcher reported that the presence of art posters in the workplace — particularly artwork featuring nature scenes — lowers both anger and stress levels in men. Interestingly, there was no discernable impact for women.
Based on the results of these studies and several others involving different patient groups, school age children and office employees, we recommend consideration of nature artwork for a wide range of settings.
Mother Nature Meets Interior Design
Artwork is far from the only option in our toolbox for incorporating natural shapes and forms into interior design features and finishes. Other options include botanical motifs, tree or columnar supports, animal motifs, shells and spirals, egg, oval and tubular forms.
3. Natural Patterns and Processes
These elements take things a bit further by incorporating natural properties into the built environment rather than just simulating these shapes and forms. A good way to think about this is how a stream moves and changes over time, the effect of wind on a field or the sights and smells of rain. For interior design, this means incorporating features that provide sensory variability, information richness, reflect age, change and patina of time, and/or incorporate growth and efflorescence (gradual unfolding of a maturation process).
Specific examples could include fish swimming in an aquarium, water moving in a fountain or a flickering fire. Another example would be a light fabric window treatment that can move with breezes coming in and allows filtered changing light to stream into interior spaces.
According to Stephen Kellert in The Practice of Biophilic Design, people tend to respond positively to information-rich and diverse environments that present a wealth of options and opportunities, as long as the complexity is experienced in a coherent and legible way. For example, fractals are a geometric form often encountered in the natural world, where a basic shape occurs in repeated but varied and predictable ways that contribute both variety and similarity to a setting.
4. Light and Space
These elements relate to the qualities of light and spatial relationships, valuing natural light over artificial forms while also including elements such as diffused or reflected light, shadow, spaciousness, spatial variability and inside/outside spaces. RLPS interior designers coordinate with the electrical engineers to provide multiple lighting sources and dimming capabilities. Some communities are using tunable LED lights that gradually transition from blue light in the morning to red in the evening to mimic the way that natural light changes throughout the day and supports the body’s natural circadian rhythm.
We typically recommend multiple light sources including decorative and task lighting to allow the end users to control light for personal comfort. Window treatments are typically selected with the goal of preserving daylight to the greatest extent possible.
5. Place-Based Relationships
Research indicates that we not only prefer natural settings to man-made environments but also favor expansive views from a position of refuge. For interior spaces, this could be a cozy window seat tucked into a corner from which to view the outdoors, feel the sunlight streaming in or open the window to hear the sounds of nature and feel the wind. Creating a focal point, like a fireplace can help organize and define a space, connecting several little parts into a visual whole.
Culturally and Geographically Relevant Design
Another important consideration is connecting spaces with the bio-cultural context of their location, reinforcing a sense of place and connection – geographically, historically, ecologically, and culturally. In practical terms, this translates to selecting materials, finishes and artwork that are relevant and unique to the location where the space exists. Other criteria include interior design strategies to encourage and aid people with navigating an environment through transitional spaces. The spaces in between such as corridors, thresholds and indoor-outdoor links such as porches or patios can help to subtly guide people through spaces.
6. Evolved Human-Nature Relationships
The elements of evolved human-nature relationships, focus on the fundamental aspects of the inherent human relationship to nature. In the book Place Advantage, Dr. Sally Augustin surmises that years of evolution have developed our desire to surround ourselves with natural elements. She provides the examples of animals in the Serengeti seeking shelter of the trees to provide respite from the harsh heat and glare of the sun.
Humans similarly tend to prefer spaces with dappled light, creating soft shadows rather than unfiltered, intense, artificial lighting. Effective biophilic design goes beyond our affinity to nature to also address how we engage with the world around us.
According to Stephen Kellert, “Prospect and refuge, order and complexity, curiosity and enticement, change and metamorphisis, security and protection, mastery and control are all elements of a more complex relationship between humans and nature that reveal our evolutionary influences.”
The below photo from Medford Leas evokes a feeling of comfort from the sense of prospect and refuge. We are looking out over the patio from the protection of the shade canvas.
Kellert further asserts that the effectiveness of biophilic design depends on interventions that are connected, complementary, and integrated within the overall environment.
For most of us, our love of nature is simply second nature. However, when we take a look at the research, we understand how important biophilic design truly is for our clients, our communities and ourselves.
