Vertical landscaping is a new technology inspired by nature. Which can be used either for the exterior or the interior purposes and under various climate. It brings vegetation to the crowded spaces thus making buildings more attractive.

The concept of vertical landscaping was first given by French Botanist Patrick Blanc, around 20 years ago. With an aim to recreate ecosystem found in the forest in his own apartment he looked into nature for an inspiration.

He realized that many plants can grow without soil with their roots developing through the substrate such as moss or algae.

Vertical landscaping generally includes woody or herbaceous climbers either planted on the ground or in planter boxes with substrate filled in them.

Supporting systems are sometimes necessary to provide irrigation facility for planter boxes.

Four factors which are making vertical landscaping important factors are

  • Advances in horticulture
  • New inventions in building materials
  • Growing environmental awareness
  • The scarcity of open green spaces.System Requirements:
  • Supporting elements
  • Growing media
  • Vegetation

Drainage vertical landscaping can be classified into 3 types 

  • Green Facades: Easiest and the simplest form of vertical landscaping in which walls are simply covered with climbing plants or cascading vegetation.
  • Wall vegetation: Vegetation growing at the surface walls especially in joints or cracks. This is a natural spontaneous process and therefore has irregular growth.
  • Living wall systems: They differ from green facades in a way that vegetation rooted in the substrate is attached to the wall itself with the help of planter boxes and a supporting system. 

Technical details

A frame is erected, as vertical beams or latticework. For exterior green walls either aluminium, galvanized steel, stainless steel, or some other non-rusting metal can be used which is firmly attached to the building or structure.

Waterproof panels are then fastened to it. For interior green walls, framing is done with wood beams since no moisture can go behind the waterproof panels. Frames have an air space between the panels and the existing wall which is approximately 1.5 to 2 inches and also enables air to circulate freely behind the wall.

The practice of going green vertically can also improve residents’ health, both mentally and physically. Green color brings the feeling of harmony to people’s mind.

Waterproof panels are made up of recycled synthetic fibers spun into a nonwoven matrix. Plants are placed between the two layers of material in pockets. The inert substrate, such as perlite or vermiculite, in used in place of soil as the substrate holds the water longer. The roots of the plants are free to grow throughout the whole vertical garden.

A drip irrigation system allows the water to slowly percolate downward. Harvesting and irrigating with rainwater is recommended and when used diminishes the number of required nutrients.

There are many advantages and claims on what vertical greening systems are capable of, such as

  • Aesthetically appealing and can protect the wall against graffiti.
  • Filter air particulates which improve air quality.
  • Reduce the urban heat island effect.
  • Provide sound insulation.
  • Moderate a building’s internal temperature via external shading.
  • Create a microclimate, which will help to alter the climate of a city as a whole.

Improve the insulation properties in summer and winter Sustainable aspect 

At present we l human development and environmental conservation. The US Green Building Council and Canadian Green Building Council’s Leadership in Energy and Environmental Design (LEED®) rating systems have are now being used as the basis for green building procurement and in some cases regulatory requirements. Green walls can contribute to securing up to 18 credits under the LEED® for new buildings. Therefore, there is a need to have more green walls installed as part of registered LEED buildings.

As the term itself suggests, Vertical Landscaping refers to the vegetation growing vertically or in other terms wall covered with live vegetation.

Other terms which are used interchangeably for Vertical landscaping are living wall, green wall, green facades, vertical garden, sustainable Architect etc. So, it can be concluded as an Integration of verticality in landscaping with Urban built environment.

Green facades cover large facade area and even protect the wall against the rain & snow, it can dry out its foundations, it will cool it down to save ventilation cost. And their impact on the cooling effect that they can have on a city temperature as well as their capacity to regulate rainwater still need to be shown.

The  Arch point does these works. Green walls in the future can be an important tool to solve future energy, space, and water.

So at the question of why do, we do green wall?; the answer will be: for us, for now, for the future.
