A living wall or Green Wall offers numerous benefits at economic, ecological and societal level. A living wall helps to purify the air, to reduce the ambient temperature, to regulate the temperature and promotes biodiversity in the city. Living walls are part of climate-proof construction. What's more, people are happier in a green environment than in grey surroundings. Below we explain the benefits one by one.
Purifies the air
The plants in a living wall filter particulate matter from the air and convert CO2 into oxygen. 1 m2 of living wall extracts 2.3 kg of CO2 per annum from the air and produces 1.7 kg of oxygen . With a living wall you contribute to air purification.
Reduces the ambient temperature
Plants absorb sunlight, 50% is absorbed and 30% reflected; so this helps to create a cooler and more pleasant climate. For the indoor climate this means that 33% less air conditioning is required, which in turn means energy savings. An outdoor living wall also has a positive influence on the heat-island effect in the city. Overall, it means a 3°C reduction in the city.
Reduces ambient noise inside and outside
A living wall acts as a sound barrier to your building. It absorbs 41% more sound than a traditional facade and this means that the environment is much quieter, both inside and outside your building. This results in a reduction of 8 dB, which means that ambient noise is halved
Healthy indoor climate
Greenery promotes a healthy indoor climate. Complaints such as irritated eyes, headaches, sore throats and tiredness diminish. In offices where there is plenty of greenery, there is a noticeable decrease in absence due to illness.
A green workplace can result in a 15% increase in productivity. Plants have a positive effect on people. This is also reflected in employee satisfaction
Offers healing environment
Greenery encourages faster recovery for patients, resulting in a shorter hospital stay. A persons tolerance of pain is higher in a green environment. This is also known as a ‘healing environment’.
