Living walls on the outside of buildings are popular in today’s increasingly built up surroundings, and it is not difficult to see why – they can provide a touch of nature to an otherwise concrete dominant world.
However, why restrict living walls to outside when they can bring a multitude of benefits to the indoor environment too, particularly offices? It may surprise (and alarm) you to learn that there is such thing as indoor pollution. This pollution consists of an array of toxic fumes, and is particularly the case in offices with certain types of furniture containing hidden, potentially harmful chemicals. Green walls are made up of plants that can absorb pollutants from the air. One wall can contain over a thousand plants that can filter air as well as creating energy-rich oxygen.
Green walls indoors can go someway to protecting our eardrums too! It can be quite overwhelming to be in a room full of people and feeling you have to shout just so the person you’re talking to can hear. This is because the reverberation created by voices, music and other sounds bounces off the walls, ceilings and other hard objects in the room. Plants can help dampen this form of noise because the leaves reflect and absorb acoustic energy.
What’s more, indoor plant life can help to save energy during the summer months. Plants cool their surrounding environment slightly and with each additional plant, this increases. Therefore, a green wall made up of hundreds of plants can actually reduce the temperature of a room.
Although the science speaks for itself, there are further therapeutic sides to living walls in offices – after all, green walls are essentially living works of art! Studies have shown that people instinctively feel more relaxed and calm around greenery. According to studies carried out at American and European universities, simply having a view of plants in a working environment gives positive psychological responses. This can lead to greater productivity and efficiency of staff, culminating in increased earnings for an organisation. What’s not to like?
