Biophilia at a glance

Biophilia is the intrinsic human tendency to interact or be closely associated with nature. In fact, the instinctive bond between human and nature is called Biophilia.

The word of biophilia was firstly used by an American psychologist Edward O. Wilson in 1980, when he observed how the increase of urbanization leads to disconnection between human and nature. This is in direct contradiction to utilization of the beneficial aspects of nature for human being.


Why do we need Biophilia in our life nowadays?

The World Health Organization has predicted that diseases caused by stress such as mental disorders and cardiovascular diseases will be the major part of illnesses in 2020. Due to attenuation of the connection between human and nature, increasing pressure on urban space, and presence of technology everywhere, there is no chance for humans nowadays to recover their physical and mental energy. Studies exhibit that the combination of direct or indirect natural elements in the human living environment is able to reduce stress, blood pressure, heart rate, and can consequently increase efficiency and creativity.


Biophilia in context

The use of natural elements in the living and working environment can lead to reconciliation of modern human with nature. One of the most important natural elements which is able to objectify the biophilic phenomenon and to provide a good feeling in human is Living-Wall or Green-Wall.


Benefits of Green Walls
  • Aesthetics: We attempt to create and offer spectacular landscapes and picturesque views to anybody watching the green walls like a painting which contains different beautiful colors and textures or walking in a pretty garden full of various types of flowers and plants.
  • Building protection: The green walls are able to prevent the corrosion and fracture of the materials used in the buildings by means of reducing the variations of temperature on the external surface of the building as well as inhibition of UV-light penetration.
  • Property value: Many studies about the real estate appraisal in the western countries demonstrate that the properties equipped by green wall systems are 20% more expensive in average than the ordinary properties. On the other hand, customers are more interested to buy the properties with green wall technology. Also, it has been proved that the calm environment created by the green walls assists the customers for stress relief and hence attract them to recreation and shopping centers, café, restaurants, gyms, and hotels.
  • Indoor air quality: We are always surrounded with polluted air in our homes and working places. Poisonous gases such as Formaldehyde, Trichloroethylene, Carbone monoxide, Benzene, and many other gases are inhaled every day by humans. Fortunately, almost all those gases can be attracted by the plants used in the green walls. The use of plants, which play the role of oxygen-generation and filtration, significantly improves the indoor air quality.
  • Energy saving: The green wall systems decrease heat transfer to the indoor environment at least 10. In addition, the interior green walls are efficient to save energy in the summers.
  • Sound proof: It has been shown in different studies that leaves attract sound energy and prevent its reflection. Therefore, the green walls consisting of numerous plants are known as acoustic elements. The use of plants on the external walls could also hinder the noise and sound reflection in urban spaces.
  • Sustainability: The green walls are able to reduce energy consumption in the buildings and consequently produce less carbon. In fact, the different components of the green walls act as a shield on the building against sunlight and heat penetration decreasing the use of cooling systems. Additionally, smart systems used for exposure, irrigation, and nourishing are able to reduce the maintenance costs of the system.
  • Health and wellness: Life in urban spaces is surrounded by concrete, iron, traffic jam, and noise. Such a life can adversely affect our physical and mental health. Plants subtlety can definitely help stress relief and relaxation. To achieve this, the green walls are used as a connection between the modern cities and nature. It has been demonstrated that the clinical therapies are improved in the hospitals located in the gardens or forests. Air quality is also improved by the plants. With the help of biophilic design, people mostly feel comfortable and relaxed in the environments surrounded by the plants. It has been proved that the employees working in the offices equipped by the green walls have higher performance and their reactions are mainly positive.


Benefits of green walls compared to roof garden
  • Constant companionship with natural elements in daily life
  • The indoor green walls are always fresh and clean as they are located in a roofed place
  • The maintenance cost is much cheaper than the roof-gardens due to utilization of smart electronic systems
  • The initial cost is much cheaper compared with the roof-gardens as they do not need insulation and pre-installation considerations
  • The green walls act as a natural insulation against noise because of their acoustic capabilities
  • Reduction of the pollutants using oxygen generator plants and absorbent of the pollutants such as Benzene, Formaldehyde, Xylene, and etc.
  • Reduction of water consumption compared with the roof-gardens

Some of the suitable places for installation of the green walls:

  • Restaurant and café
  • Hotels
  • Hospitals and clinics
  • Luxurious buildings
  • Inside the residential buildings
  • Waiting rooms
  • Commercial and administrative centers
  • Sport centers and gyms
  • Educational centers
