Several studies have shown the positive impact of green walls on the occupants. The green walls help to keep the environment fresh thereby boosting up the mood of residents and promoting productivity. Some of the positive impacts that green walls have include promoting a better emotional state, better task performance, and an improved psychophysiological state.

This further has a positive impact on health by reducing the negative impact caused by dirt accumulation in public spaces.

03. Noise Reduction

Not many may know, but living walls are also helpful in regulating sound in buildings and outdoors. The plant foliage attracts and absorbs any kind of acoustic energy. Thus, green plants help reduce noise in echo-prone areas. The similar kind of benefits are present in outdoor green walls. People are using these exterior green walls to combat the impact of noise pollution due to traffic.

04. Habitat Restoration

The virtual gardens are an artificial extension of nature which further acts as a residence for different species like butterflies, insects, hummingbirds and more. A lot of companies are including larger green walls in the office spaces, which is further promoting the habitat restoration for insects. The lack of habitat for insects is one of the biggest problems in urban areas, but the green wall contributes towards solving this problem.

Increase in the heat island effect, particularly in urban areas is proving to be a threat to the urban world. As a result, it is necessary to maintain the temperature for proper functioning. Most of the urban heat islands are occurring due to the absence of adequate greenery in the living spaces, including open spaces.

Increasing the number of green walls in urban spaces can help to combat the heat. They will eventually absorb the heat and cool the entire environment by the process of evapotranspiration. Compared to interior installations, the exterior green walls are proving to be more helpful as they can cool the entire building by preventing heat from entering the buildings. Many countries have now made it compulsory to create green spaces that combat heat islands.

(b) Business Benefits

Apart from the visual and environmental benefits of green walls, one cannot overlook their economic benefits. Some of them are mentioned as under:

01. Lower Energy Consumption

As mentioned in IGBC Guidelines, the energy-saving could range from 20 – 30 %.

Green Walls Lower the Energy

The plants are combined with building materials to ensure that less heat is transmitted. As a result, air conditioning needs are lowered. Similar to the exterior walls, the interior green walls can have a similar impact. Plants will absorb heat and keep the temperature cool, thereby saving energy cost.

02. Better Productivity – Biophilia

The presence of nature in the workplace can help to boost productivity and morale. Green walls bring about Biophilia.

According to ‘Judith H. Heerwagen’, (Published in Design, Productivity and Well Being: What are the Links?) Biophilia refers to an innate instinctive bond between humans and other living things, “the evolutionary ties between people and nature.” Various studies have shown that it is due to the biophilia that many people have noticed a boost in their mental health, low blood pressure and a jolly mood throughout.
