Green Walls Benefits

Whereas once the greening of buildings was left largely to nature, modern construction materials and methods make the practice more scientific, sustainable and long lasting – ensuring that the benefits derived are not at the expense of the integrity of the building structure.

Green Wall systems combine great design scope with a number of ecological and performance benefits:

Improves aesthetics

A well designed and maintained Green Wall can significantly enhance a building’s appearance - whether it’s to add a new aesthetic dimension, disguise a car park, refresh a tired façade or add colour and texture to a complete wall or section.

Regulate temperature and reduce carbon footprint

A green wall used on appropriate elevations can reduce energy costs by both providing an additional layer of insulation in the winter (keeping heat in) and acting as a screen to the sun in the summer (keeping the building cool).

Protect building façades

Green wall systems can help to protect a building’s façade and extend its life, acting as an effective shield to heavy rain and hail and helping to protect from the damaging effects of UV light.

Provide wildlife habitats

With a strong base from the trellis and appropriate planting, a green wall can provide an ideal habitat for wildlife. In many cases, it can also provide an alternative habitat for any wildlife displaced during construction, with the option of integrating bird houses within the structure.

Improve air quality

A green wall in an urban area can help improve local air quality, both by absorbing carbon dioxide and releasing oxygen, and by trapping dust and other pollutants.

Deter graffiti

In areas where graffiti is a potential problem, green walls can act as an effective deterrent, making the application of graffiti to the building structure almost impossible.

Reduce noise

By adding a layer of insulation (both thermal and acoustic) green walls absorb sound - making a positive impact for both the building’s occupants and the local environment.

Green Wall Applications

Green Wall technology may be used for a wide variety of projects - both new build and refurbishment for a variety of building types.

From small garden projects to large industrial and commercial developments, the benefits of Green Wall systems are being realised across the public and private sectors.

With carbon reduction targets a key focus for many public sector organisations (particularly schools and hospitals), Green Walls can play a contributory role, significantly helping to reduce a building’s carbon footprint.

In schools the systems can also deliver educational benefits, encouraging pupils to engage with the problems of carbon reduction and climate change and with broader ecological and environmental issues. Specific systems can be designed to suit a range of plant types, and as a habitat for different wildlife.

Green Wall systems require very few small fixings and therefore the impact on, or potential for damage to a building’s façade is minimal. Similarly, the system is set away from the wall so, with the correct plant choice, plants will not damage the façade and systems may be used with confidence on existing buildings, even those that may be listed.

Recent developments in vertical faming techniques also demonstrate the potential and versatility of Green Wall systems. Using large urban structures to grow crops on their facades, buildings would become ‘farmscapes’ - effectively with green walls providing a sub-structure to support the growth of crops such as fruit and vegetables.
