How can you design a green wall to purify air in urban environments?

It is very important to choose the exact location for choosing the plant and the type of irrigation and maintenance of the green wall. In our country, Iran, there are different climates, for each of which a different plant is suitable. For example, in the north of Iran, the climate is moderate and humid, and the desired plant should be able to absorb a lot of water in the green wall due to the rains in the region. In the south of Iran, the weather is hot and humid. In addition to adapting to the weather, the plant should be able to solve the main problem of the area, i.e. excessive dust, and be used as a green wall to reduce dust.

Designing a green wall, also known as a living wall, to purify air in urban environments involves selecting appropriate plant species and implementing effective design strategies. Green walls can contribute to air purification by absorbing pollutants, releasing oxygen, and providing other ecosystem services. 1. Select Air purify Plants 2. Consider Plant Traits 3.

Location is very important for the green wall installation. The goal must not just to purify the environment but also to make it a focal point for the viewers, visitors and inhabitants of the area. Also you need a irrigation plan for this and accessibility for the maintenance team. So choosing a location which can gives a good view to the maximum people and which is nor too much hard to access for the maintenance team will be preferred by me. As far as the matter of purifying the air is concerned, this can be achieved by the plants automatically. One more thing which I would Like to add is about the selection of plants. There are a many plants species which can absorb more carbon elements than others. One must chose the plants wisely.

Plant Selection: Choose native, pollution-tolerant plants with high surface area leaves, like ivy, ferns, and certain grasses. They'll be more effective at capturing pollutants and thrive in the urban environment. Irrigation System: A well-designed irrigation system ensures your plants receive the right amount of water without wasting resources. Consider rainwater harvesting or greywater systems for a sustainable approach. Vertical Structure: The structure supporting your green wall should be lightweight, durable, and weatherproof. Modular systems offer flexibility and ease of installation. Maintenance: Regular maintenance is crucial for a healthy green wall. This includes pruning, pest control, and monitoring for potential issues.

I agree with Maya - the exact location will determine what plants will grow where the - statement applies only to the northern hemisphere.

Non pollinating tropical plants generally are a good place to start however, once the tropical plants are selected, it’s less about the plant types and more about how the plant is grown. Geoponic or soil based systems will restrict the plants ability to clean the air by covering the microbes within the rootzone that do 98% of the heavy lifting. Planting the system with hydroponically grown plants overcomes this issue as the plants rootzone is completely exposed allowing the microbes to access the active airflow within the system and scrub the air of indoor air pollution.

Selecting the right plant is the major decision to be taken while executing green wall because if everything is in place and we select a wrong plant based on the location and light conditions, the green wall will eventually fail. We should make sure we select a hardy plant to a place where the location is open to more light and pollution, at the same time we must ensure that watering / irrigation to be considered based on the plant because not all plants require same amount of water and at same intervals .

Das ist ganz einfach. Man pflanzt 1 Parthenocissus tric. Veitchii je 2 m an die Wand. Fertig. Also gut. Es werden 125 Zeichen gewünscht.

Chose the plants with shallow root systems and broad leaves. Play with color to add the beautification. Hanging perennials can be very good.

Try and use native, indigenous species. This will help in developing the local ecosystem. Many species can be propagated using the cutting generated out of these.

It's important to consider how polluted air is forced through areas of the living wall that have the ability to filter air. This can be done through onboard fans or even air handling units in the building. The advantage of hydroponic living walls is that you can force air through the root zone of the plants (which have microbes useful in metabolize VOCs), in addition it is low pressure since the growing medium should be porous. This reduces energy used by fans and improves removal efficiencies.

Design the structure in accordance to the irrigation. A firm and quality frame must be used to support the Plants weight. But if you are only going to plant a creeper which can climb the wall, You may not need any frame. Just plan something which can hold the branches of your vine.

It’s important to consider the structural requirements of a green wall, specially if you’re dealing with vegetated mats or modular systems. Generally, we often underestimate the amount of stress and load these systems put on the buildings or the primary structure wherever they are installed. It is, therefore, important to involve a structural designer along with plumbing consultant and other co professionals at the concept stage itself.

A estrutura deve ser vista para além do suporte que prestará a vegeta??o. N?o basta somente haver espa?o para inser??o de terra ou água (no caso de hidrop?nicas) mas sim prever algo que irá funcionar como um organismo que é fácil de fazer manuten??o, sem precisar retirar as plantas quando sofrem de alguma infesta??o de organismos, por exemplo.

Using a site readiness sheet is critical for a smooth living wall installation, serving as a formal agreement that the site is ready. It's essential for several reasons: It acts as a checklist to ensure the site meets all conditions for plant health. The sheet also confirms that the site is clean and prepared, preventing plant damage and extra expenses from premature plant installation or site unpreparedness. The sheet aligns all parties on the schedule, streamlining the installation process. The document can also serve as a legal safeguard, detailing financial responsibilities. It's a pivotal measure for the project's success and the living wall's durability.

Installation of any green wall system will depend upon the context, system typology, plants, and the requirements of the system. Generally, manufacturers and vendors “market” these products as “one solution for all types” but that’s not the case. Its important to understand that integrating the green wall system with your building structure requires precision and a sufficient tolerance for errors, as these are “live” systems and to predict how they are going to behave is not possible at an initial stage. Therefore, the installation of a green wall is not a one-step process, it’ll require continuous monitoring and tweaking the design as per the performance over a given period.

Beyond structural requirements, if the greenwall is to clean air - onboard fans and or integration with the building HVAC system must be considered. An installation will not sufficiently clean air without that air flow being directed into the rootzone with some form of mechanical component guiding it.

In my experience, it happens too many times that green wall maintenance is often not discussed early enough in the design phase, resulting in an underfunded maintenance program and leading to the project's failure. Maintenance is not an afterthought but an integral part of a living wall's design and budget. It's vital for the wall's sustainability and the benefits it provides.

Most of the green walls fail because of bad maintenance. The success of the green walls depend on the amount of discussion on it’s maintenance during the design and installation phase. In my opinion ,maintenance is not just watering the plants, we have to make sure that the right amount of manure or fertiliser is given timely. Also, we have to make sure that the dried leaves are removed, the dust is properly cleaned and most importantly we have to clear the pests and mealy bugs immediately after it attacks the plant by using appropriate pesticides.

Es importante que cuando se proponga un muro verde recalcar la importancia del mantenimiento, este paso puede llegar a ser el más costoso al momento de construir un muro verde, porque va requerir de una revisión continua y constante. Lo ideal serían sistemas de riego con moto bomba, estar pendiente de las plantas que requieran ser reemplazadas y hacer la debía fertilización.

Maintenance of a green wall is the primary “barrier” in their implementation. Most of the systems that are available currently are extremely maintenance-intensive and require a huge amount of work and costs. The systems should be designed in a way that regular maintenance can be done easily and effectively without having to alter the environment. The pruning of the plants, along with the amount of bio-waste because of dead leaves and stems is an important aspect to consider, along with watering requirements. Majority of the green walls fail because of poorly designed irrigation systems. Additionally, one should also consider that the sizing of the irrigation systems should be able to accommodate recycled water and must not fail.

this is the key element to proposing a green wall. How to manage the maintenance. specially if you have a very low rain average per year. and you have to depend on irrigation. even with an automatic irrigation system, you'll have to use plants that can be more resilient. besides the texture and color you might want to use with your design. probably the guidelines should be the resistance of the plans.

Inherent benefits are understood when it comes to nature based systems. Ongoing, a company should have some form of monitoring and measuring to reflect the benefit (in this case, air quality) above and beyond the assumption that plants clean the air. Realizing this benefit through data collection is one strong method of doing so.

Paredes verdes desempenham um papel crucial no espa?o urbano, oferecendo benefícios ambientais, econ?micos e sociais, ambientalmente, contribuem para a purifica??o do ar, absorvendo CO2 e liberando oxigênio, enquanto reduzem a temperatura local e controlam a polui??o sonora, economicamente, melhoram a eficiência energética de edifícios, resultando em economia de custos. A estética aprimorada valoriza propriedades e áreas urbanas, atraindo investimentos, socialmente, proporcionam espa?os agradáveis, beneficiando o bem-estar dos habitantes, e criam habitats urbanos, promovendo biodiversidade.

When using vegetation to filter air, especially particulates that are trapped on surfaces, designers and managers must consider what happens to the plant biomass. Deciduous leaf drop and decomposition can cause an accumulation of particulates on the ground surrounding the green wall. If the green wall is collocated with sensitive populations, such as a play ground for kids, the green wall may be incidentally increasing exposure to pollutants.

Beyond air quality, living walls are more consistently recognized for other benefits, such as mitigating the urban heat island effect for cooler cities and reducing energy use in buildings. They enhance urban biodiversity by providing habitats for various wildlife, which is crucial for ecological balance. Moreover, the biophilic design of these green spaces takes center stage, significantly improving mental health and cognitive function, thus elevating the overall quality of urban living.

Es un elemento “artificial” donde las plantas requieren más atención por parte de sus mantenedores ya que no están plantadas en plena tierra. Es una buena solución si no tienes tierra y deseas vegetar un muro.

Hay que tener en cuenta que un muro verde requiere de un buen mantenimiento y suficiente agua para que se sostenga en el tiempo, esto puede implicar que al momento de querer mandar hacer uno es probable que ese factor del mantenimiento sea lo más costoso de la obra

Paredes verdes, ou jardins verticais, s?o inova??es urbanas que contribuem significativamente para a purifica??o do ar e melhoria dos ambientes, essas estruturas, com plantas crescendo verticalmente em fachadas, absorvem CO2 e liberam oxigênio, promovendo a qualidade do ar, além disso, reduzem a temperatura urbana por meio da evapotranspira??o, melhorando a eficiência energética, a diversidade de plantas em paredes verdes também cria habitat para fauna urbana, promovendo resiliência ecológica.
