Green Wall as a Part of Your Enjoyment

Share |

How great can it be to be surrounded by the green wall with its gorgeous flowers, to smell their fragrance, to hear the bees buzz, to see pretty butterflies with their beautiful wings, and all this makes for a very relaxing and enjoyable time. Green wall will make your room or yard look even better than it is now. The look of a very green fence around your house is the best thing you could ever have.

A Green Wall

A green wall is a wall, either a free-standing or an integrated part of a building that is particularly or completely covered with vegetation and, in some cases, soil or organic growing medium. The concept of green wall dates back to 600 BC with the Hanging Gardens of Babylon. The modern green wall with integrated hydroponics was invented by Stanley Hart White at the University of Illinois Urbana-Champaign in 1931-38. A green wall is either a hedge that is entirely composed of plants, such as shrubs, or a wall that is partially or completely covered by plants.

Green wall is a key component of living architecture and it will become increasingly important fixtures in our cities in years to come. The technologies provide a good range of options for designers who are interested in using the building envelope to accomplish multiple objectives and to provide new free-standing design features on the exterior and interior of buildings.

Types of Green Wall

There are two main categories of green walls: green facades and living walls. Green facades are made up of climbing plants either growing directly on a wall or specially designed supporting structures. The plant shoot system grows up the side of the building while being rooted in the ground. With a living wall the modular panels are often made of stainless steel containers, geotextiles, irrigation systems, a growing medium and vegetation.

Functions of Green Wall

The plants reduce overall temperatures of the building, which in turn reduces energy consumption. They may also be the means for water reuse. The plants may purify slightly polluted water by absorbing the dissolved nutrients. Bacteria mineralize the organic components making them available to the plants. Green walls are suitable for cities, as they allow good use of available vertical surface areas. They could also function for urban agriculture or urban gardening. They may be built as works of art and for their beauty. They are sometimes built indoors to help cure sick building syndrome.

Advantages of Green Wall

Having created a green wall you will get the benefits in increasing the life span of the waterproofing membrane, cooling exterior and interior, reducing heat off the building, reducing toxins in the air, adding oxygen to the air, adding to the aesthetic value of the property, reducing traffic noise, giving shade, and designing and engineering for any façade. Another significant advantage is the increase infiltration and storage of rainwater through their root systems. They can be complete ecosystems or simpler configurations of plants that thrive and help to decontaminate urban environments. Many green walls are built indoors, but they can also be brought outdoors, such as on the exterior walls of buildings.

Three Types of Growth Media

There are three types of growth media used in green walls: lose media, mat media and structural media.

Loose Media

Loose medium wall tend to be “soil-on-a-shelf” or “soil-in-a-bag” type systems. Loose medium systems have their soil packed into a shelf or bag, which are then installed onto the wall. These systems require their media to be replaced at least once a year on exteriors and approximately every two years on interiors. Most importantly, because these systems can easily have their medium blown away by wind-driven rain of heavy winds, these should not be used in applications over 8 feet high.

Mat Media

Mat type systems tend to be either coir fiber or felt mats. Mat media are quite thin, even in multiple layers and as such cannot support vibrant root systems of mature plants for more than three to five years before the roots overtake the mat and water is not able to wick through the mats. The method of reparation of these systems is to replace large sections of the system at a time by cutting the mat out of the wall and replacing it with new mat. This process compromises the root structures of the neighboring plants on the wall and often kills many surrounding plants in the reparation process.  Mat media are better suited for small installations no more than eight feet in height where repairs are easily completed.

Structural Media

Structural media are growth medium “blocks” that are not loose, nor mats, but incorporate the best features of both into a block that can be manufactured into various sizes, shapes and thicknesses. These media have the advantage that they do not break down for 10 to 15 years, can be made to have a higher or lower water holding capacity depending on the plant selection for the wall. Depending on the installation, they do tend to be more expensive to install, but lower cost in maintain.

Constituent Flora

Some popular plants include:

  • Actinidia
  • Akebia quinata
  • Aristolochia
  • Campsis
  • Celastrus
  • Clematis
  • Cotoneaster
  • Hedera
  • Heuchera
  • Humulus lupulus
  • Pyracantha
  • Wisteria
