People who live in cities are subject to various risks because of the dense cities and a large number of moving vehicles. These include street noise, extreme temperatures, and air pollution. Large cities also have trouble keeping comfortable due to excessive energy usage for heating and cooling. Introducing green walls is one option for minimizing the aforementioned negative impacts. Plants clean the air of contaminants, produce oxygen, provide thermal insulation when put on exterior walls, and have pleasant psychological implications.
What is Green Walls?
A green wall is a type of wall with soil or another substrate and is entirely covered in vegetation. It is also referred to as living walls or vertical gardens. Climbing plants make up the majority of green walls. However, there are other options that architects have employed in which the plants are cultivated in an environment that includes development media like soil. It consists of an integrated water delivery system that provides insulation to maintain a stable internal temperature.
The green wall offers benefits such as foliage, fresh air, and others. The building’s internal temperature may be adjusted and maintained with the help of a green wall. It also decreases air and noise pollution and promotes water efficiency.
Most green walls have automated drip irrigation systems, which maximize water use and minimize waste. The most effective method is to pump water repeatedly from the bottom to the top of the tank until there is no more, at which point the tank is refilled. Direct irrigation is an alternative when there is no room for tanks, while sophisticated walls may use rainwater capture systems.
How are Green Walls constructed?
Green walls are constructed using a skeleton framework divided into parts that hold the plants and flowers that will make up the wall.
- Panel systems: putting pre-planted plants on wall panels. They are fixed directly onto a building’s wall utilizing a support framework and can be used indoors or outdoors in any environment.
- Felt systems: Plants are placed in felt pockets, and pipes are inserted through the wall to maintain moisture in the felt to support plant growth.
- Tray systems: These plants are put into the wall and are commonly used inside. They are cultivated off-site, giving them adaptability and the ability to cover huge surfaces.
- Trellis systems: Container-grown plants are trained to climb a wall trellis.
- Freestanding walls: Frequently utilized indoors and most adaptable, allowing for easy relocation or plant replacement.
Typically, wall plants are chosen for their ability to purify the air, resilience, wide range of tolerances, ability to resist extreme weather, and other factors. Some plants require soil, while others don’t.
