Restorative Biophilic Design

Land Planning, Architecture and Collaborative Design promoting
Physiological and Psychological Health and Well-Being

Building Places that Re-Connect with the Natural World.

“The goal of biophilic design is to create places imbued with positive emotional experiences—
enjoyment, pleasure, interest, fascination, and wonder—
that are the precursors of human attachment to and caring for place.”
- Judith Heerwagen Ph.D.

Biophilic Design

Biophilic elements have demonstrably real, measurable benefits for human performance metrics such as productivity, emotional well-being, stress reduction, learning, and healing.

Biophilic features foster an appreciation of nature, which can lead to greater protection of natural areas, species conservation, and pollution prevention.


Restorative Elements and Attributes of Biophilic Design

Definition of Biophilic Design

The word “Biophilia” was popularized by the Harvard Biologist and Zoologist E.O. Wilson in 1984.

It refers to the inherent human inclination to affiliate with natural forms, systems and processes, especially life and life-like features of the non-human environment. 3

Biophilic Design translates this affinity into the design of buildings and places, which are instinctively experienced as restorative, neurologically nourishing and beautifully alive.

Biophilic Design incorporates Green Building, but considers that true sustainability must include quality of life issues involving human physiological and psychological health and well-being. 2


Why the Need for Restorative Design?

Evidence is mounting that we need to look to restorative attributes that allow us to re-connect with nature.

Many of the psychological ailments of our time such as depression, SAD (seasonal affective disorder), anxiety, violence, confusion, isolation and loneliness, as well as many of the physiological problems of our time such as sleep disorders, fertility issues, increased cortisol levels, allergies, asthma and even cancers may directly or indirectly be related to the way we have designed and structured our indoor and outdoor environments.

One common thread between all ailments, psychological and physiological seems to be that of an organism stressed, depleted and unable to cope.




Aesthetic Response

“ ….our brain evolved in a biocentric, not a machine-regulated world.” (EO Wilson 1984)

A neurological evolution-based understanding of human aesthetic responses is now being established.4

The findings come from a variety of disciplines: cognitive neuroscience, neuroscience in architecture, behavioral genetics, evolutionary biology, environmental sciences, cognitive psychology, biological anthropology, social ecology, photobiology and others.

As a species, most of our emotional, problem-solving, and constructive abilities reflect skills and aptitudes learned in close association with natural systems and processes that remain critical in human health, maturation and productivity.5

An increasing number of studies are beginning to measure a multitude of physiological and psychological benefits of sustained positive connection to seasonally dynamic natural environments.

This connection appears to be a necessity for achieving lives of fitness and satisfaction even in our modern urban society. 5

Denying this genetic dependence is akin to denying our need to breathe and eat.


Health Benefits of

Biophilic Design

Enhanced Healing, Cognitive Function, Hormonal Balance; Improved Immune Function, Stress Reduction, Reduced Cell Aging

learn more

Enhanced Healing and Recovery
  • Contact with nature and the natural variability of daylight, particularly morning sunlight exhibit enhanced healing and recovery from illness, bipolar disorder, and SAD 9; this includes direct contact (vegetation), as well as representative depictions ( images) 5.
  • Patients with tree views have significant shorter hospital stays, less need for pain medications 11 6 .
Healthier Childhood Development
Improved Attention, Concentration and Cognitive Function
Circadian and Hormonal Balance
  • Photobiology has shown that the internal circadian clock is set by daylight of specific wave lengths at different times of the day…the circadian rhythm controls the hormones in the pituitary, pineal, adrenal, and thyroid glands.
  • Regular exposure to dynamic natural sun light avoids a lack of UV-triggered melatonin production, which has been linked to sleep disturbances, carbohydrate cravings, poor performance at task, short term memory loss, depression, anxiety, increase susceptibility to disease 15 including cancer (breast cancer is melatonin sensitive) 13.
  • Relationship between circadian rhythms and cancer.
Improved Immune Function, Stress Reduction and Reduced Cell Aging
  • Regular exposure to dynamic natural sun light avoids circadian misalignment (see above), which has been linked to cortisol over stimulation, leading to increased stress, suppressed immune function, insulin resistance, obesity, osteoporosis, and cell aging 14.
  • Restoration becomes manifest in emotions and in lower blood pressure, slower heart rate, and improved muscle tension 16.
Vitamin D Metabolism
  • Human physiology evolved to require direct sun exposure for metabolism of Vitamin D for the development of a healthy musculoskeletal system, preventing rickets and osteoporosis, maintaining muscle strength, and preventing chronic diseases such as type1 diabetes and rheumatoid arthritis 8
The Healing Sounds…
  • The peaceful sounds of nature, the sounds of silence, offer welcome rest and healing from our sonically overburdened world.
  • The tranquility of a garden or garden room allows us to re-connect with our own thoughts and feelings, rejuvenates and restores our inner balance and ability to cope.
