Biophilia refers to the bond between human beings, the natural world and living organisms. In a concrete, urbanised world, vertical gardens provide a way for nature to be introduced back into daily living. Vertical gardens in office spaces and living environments not only enhance the aesthetics of a building or room, but improve the negative psychological effects associated with property demarcation. A sense of privacy and calm is created through the use of natural greenery, increasing productivity and overall psychological wellbeing.
Open plan offices and living environments are often noisy spaces. The dense growth of plants in Living Green Walls provides a visually appealing way to refract and absorb noise. Noise is often disruptive and distracting, resulting in increased interruptions and lower productivity rates. Plants naturally absorb, deflect and refract sound, and are used in various landscapes to block high and low frequency sounds. The vast number of plants used in the construction of vertical gardens increases this absorption, thereby reducing the amount of noise in that environment. The type, size and shape of the plant all has an effect on sound reduction. Living Green Walls and plant screens provide a large expanse of plants which absorb unwanted noise and instead offer quieter, restful environments in which to work or relax.
Externally, buildings are exposed to a variety of negative weather elements, such as UV radiation; a fluctuation in temperature; corrosive rain and heavy wind. As a result, building facades may begin to deteriorate and break down. Living Green Walls not only act as a ‘green’ blanket to cover the building, but they can also replace conventional rain-screening technologies. In addition, living walls assist in building protection by regulating climate control. The plants prevent drastic fluctuations in temperature which would ordinarily result in corrosion due to the expansion and contraction of the building. Living Green Walls further provide natural insulation by retaining heat in winter, providing additional warmth, and cooling the building in the warmer months.
With the rapid increase of carbon dioxide and other harmful green-house gases, there is a need for a natural way to cleanse the air we breathe. Plants not only provide us with oxygen and reduce the levels of carbon dioxide in our air, but they also naturally filter approximately 90% of the pollutants. Toxins from synthetic materials, dust and mould are unknowingly inhaled on a daily basis, often resulting in illness. Living Green Walls help filter these toxins from the air.
