Green Wall Architecture for Sustainable Buildings

Green walls can be an effective way to reduce urban heat island effects, as seen in cities like Singapore where green walls can lower temperatures by up to 2°C.

Green walls can also help to reduce air pollution by removing particulate matter and other pollutants from the air. They can even improve air quality by releasing oxygen and reducing the amount of carbon dioxide in the atmosphere.

Green walls can be integrated into building design to create a seamless and natural-looking facade. By using a variety of plant species and a well-designed irrigation system, architects can create a thriving ecosystem on the building's exterior.

Green walls can be installed on buildings of any size, from small residential homes to large commercial high-rises.

Green walls are vertical structures that have different types of plants or other greenery attached to them.

The growth medium, which can be soil, stone, or water, is often built into the wall, and irrigation systems are usually included to keep the plants healthy.

Green walls differ from facades, which use the outside walls of buildings as structural support.

In green walls, the growth medium is on the surface or structure of the wall, whereas facades are rooted in the ground.

Smart and active green walls use artificial intelligence and technology to enhance their effects, making them look similar to conventional green walls but serving more purposes.

These smart living walls can be automated and monitored, and they can even feature natural air purification and humidification thanks to enhanced air circulation and specialized growth medium.

There are three main types of green walls: panel/modular systems, tray systems, and free-standing walls.

Panel or modular systems feature plants that are pre-grown into panels and can be used indoors or outdoors in any type of climate. They bring instant gratification and visual impact to the setting.

Tray systems, on the other hand, are made up of individual trays that hold a certain amount of water, giving plants ample hydration without having to compete for it. They are commonly used indoors and are cheaper than panel systems.

Free-standing green walls are movable living walls that can be used both indoors and outdoors and can also be used as flexible room-dividers or on-demand partitions.

Biodiversity is key to a thriving green wall. Our green wall is always planted with a carefully selected mix of plants, fit to the specific situation and outdoor or indoor climate of your project.

This approach ensures that the green wall remains healthy and resilient, even in challenging conditions.

Outdoor panel green walls are primarily visual elements, used to bring greenery into urban landscapes.

They can be made of a range of materials and plants, depending on the most suitable solution for each space. Outdoor green walls have restrictions in terms of the climate, as they have to endure their surrounding circumstances.

The construction of these living walls can reduce overall temperatures, capture rainwater, or insulate buildings. This can be a cost-effective solution for outdoor spaces.

Outdoor green walls are often used in urban landscapes, but they can also be used in other outdoor environments, such as parks or gardens.

Design and installation of green walls requires careful planning to ensure they thrive in various environments. A well-designed green wall system can be installed in as little as 1-2 days.

To maximize plant growth, green walls are typically installed in areas with high humidity, such as indoor spaces with controlled temperature and lighting conditions.

The panel is a crucial component of a green wall system. It's the surface where plants are attached and grown, and it comes in different types, such as the Urbanscape Green Wall Panel that's planted with a mix of indoor and outdoor plants.

For indoor green walls, the panel is typically cultivated with a carefully selected mix of indoor plants and ferns, ensuring at least 90% coverage upon delivery. This is to create a visually appealing and lush green space that purifies the air and improves the overall ambiance.

Outdoor green walls, on the other hand, are planted with a mix of shrubs, perennials, and ferns that are specifically chosen for their ability to thrive in various climates and weather conditions. This is because outdoor green walls face harsher conditions, such as wind, sunlight, and rainfall, which can affect the health and well-being of the plants.

The choice of panel and plants also depends on the location and available technology, as mentioned in the article. For instance, in areas with arid climates, succulents are a great option as they store water in their leaves, making them more resilient to drought.

In terms of maintenance, the panel and plants work together to create a stable environment that promotes healthy growth. Regular trimming, irrigation, and nourishment are essential to keep the plants vital and thriving.

The design of a living wall is not usually limited by size, but wide models are easier to maintain than tall ones.

Manufacturing round shapes for living walls built from metal or plastic modules is harder, whereas felt is ideal for round and varying shapes.

Active green walls prioritize air circulation features, which limits most designs to solid modules.

Most indoor green walls are wall-mounted, but free-standing and double-sided models are not uncommon.

In terms of commercial green walls, most are custom-made solutions.

Building-friendly features are a crucial aspect of green wall and facade design. By incorporating plants into your building's design, you can reduce energy costs and create a more comfortable indoor environment.

Outdoor green walls and facades can reduce overall temperatures of buildings when exposed to the sun, which in turn reduces energy costs. This is because the plants absorb heat and reduce the need for air conditioning.

The transpiration process of plants can also reduce temperatures indoors, making them an energy cost-effective solution. This is especially beneficial in areas with high temperatures.

Sufficient plant matter can also help reduce noise levels, creating a more peaceful environment for occupants. I've seen firsthand how a well-designed green wall can transform a noisy area into a serene oasis.

Here's a breakdown of the benefits of different types of green walls and facades:

By incorporating these features into your building design, you can create a more sustainable, comfortable, and cost-effective space for occupants.

CAD designs play a crucial role in the design and installation process of green walls. A set of detailed Urbanscape Green Wall drawings (CAD Designs) was made to assist architects and other designers with their work.

These CAD designs are specifically created to help architects and designers visualize and plan their green wall projects. CAD designs can be customized to fit the specific needs and requirements of each project.

With CAD designs, architects and designers can ensure that their green wall projects are not only visually appealing but also structurally sound and functional.

Our green wall panels are planted with a carefully selected mix of shrubs, perennials, and ferns. This mix is designed to thrive in a variety of situations and climates.

The assortment of plants is extensively tested to ensure they can handle different conditions, so you can enjoy a lush and healthy green wall.

Indoors are more lenient for plant selections, allowing for a wider range of options.

Evergreen plants are usually preferred for both indoor and outdoor walls due to their longevity and looks. By definition, evergreen plants have to keep their leaves all year round.

For indoor green walls, houseplants and tropical plants are the most suitable options. These plants don't have to tolerate major temperature changes, but humidity can still cause issues if not accounted for.

Some manufacturers resort to using chemically treated moss or plastic plants, which trade other benefits like air purification for easier upkeep.

For outdoor green walls, the selection process is more rigorous, especially for active green walls. Plants have to be tested to ensure they can survive in an active green wall, where air circulation can be quite taxing.

A carefully selected mix of shrubs, perennials, and ferns is used for outdoor green wall panels. The assortment of plants is extensively tested to ensure it's suitable for different climates and situations.

No two green walls are alike, and each one is designed exclusively for a specific project. The plant species are chosen based on aesthetic preferences, geographical area, and other factors like light conditions and size.

Edible Plants can be a great option for your green wall, but they require some special care.

For living walls, plants like Heartleaf Philodendron and Clusia Rosea can thrive, but they're not edible.

Some plants that can be used for edible walls include, but are not limited to, herbs like basil and mint.

These plants are relatively low maintenance and can add a burst of flavor to your cooking.

Keep in mind that edible plants need more frequent watering than non-edible plants.

The right plants can make all the difference in the success of your edible green wall.

Living with green walls can have a significant impact on our well-being. Studies have shown that being around nature can decrease negative behaviors, such as aggression and anxiety.

Green walls can make us happier and more productive, as they appeal to our innate need to be around nature. This concept is also known as biophilia.

The air purification effect of plants is achieved through microbes of plant roots, which can use chemicals as nutrients. Improved air quality has been proven to advance people's alertness and cognitive abilities.

Smart and active green walls with active air circulation can achieve noticeable air purification and naturalization. This is because the wall, plants, and supporting technology are all designed for the purpose.

Green walls can be a key element in re-populating our offices successfully, as they create workplaces where people feel safe to return to and spend their time in.

A Green Roof System can be an effective solution for urban areas, providing insulation and reducing stormwater runoff.

To further enhance the benefits of a Green Roof System, a Detention Green Roof can be implemented to store and filter rainwater.

A Landscaping System can also be designed to complement the Green Roof System, incorporating native plants and trees to create a thriving ecosystem.

For a more dramatic effect, a Green Wall can be installed, providing a vertical garden that adds visual interest and helps purify the air.

Here are some key solutions to consider:

One of the most impressive things about green walls is how they can transform a building's façade into a dynamic, living entity. They create highly-efficient building envelopes, minimizing heat loss and cooling loads.

A green wall can also reduce rainwater runoff and filter pollutants out of the air. This is especially important in urban areas where air quality can be a major concern.

Green walls can be designed to sway in the breeze and change with the seasons, bringing a sense of movement and life to a building's exterior. They're not just aesthetically pleasing, but also highly functional.

By incorporating green walls into a building's design, architects can create beautiful, evolving ecosystems that connect people through fragrance, texture, and pattern. This can have a profound impact on the way people interact with and experience a building.

When designing green spaces, it's essential to consider the solutions that can help minimize environmental impact. A Green Roof System is a great option, as it helps to reduce stormwater runoff and provides insulation for buildings.

A DETENTION GREEN ROOF is another effective solution, which stores rainwater and allows it to slowly infiltrate the soil, reducing the amount of water that enters storm drains.

Green spaces can also be enhanced with a Landscaping System, which helps to create a visually appealing and sustainable environment.

Green Walls are another popular solution, which can be equipped with a drip-irrigation system for efficient watering.

The most common watering system in green walls is the drip-irrigation system, which links an Irrigation Control Box directly into the plumbing system of the building.

This automated system maximizes water usage and minimizes waste, as it can be released on a timed schedule.

The tank system or 'water tanks' is another water management system, but it is mostly seen in tray systems and free-standing green walls.

They basically need to be filled and re-filled manually, and since they aren’t connected to the building’s plumbing, they require manual labor.

Here are some common solutions for green spaces:

Green walls can be constructed using various types of media, including loose media, mat media, and structural media. Loose media is a popular choice, but it can break down over time.

Structural media, on the other hand, is a more durable option that can last for 10 to 15 years. It's available in various sizes, shapes, and thicknesses, and can be customized to suit specific plant needs.

Sheet media is another option, which uses semi-open cell polyurethane sheeting with an egg crate pattern. This type of media has excellent water-holding capacity and can be used for both outdoor roof gardens and vertical walls.

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 adequately wick through the mats.

Mat type systems tend to be either coir fiber or felt mats, which are best used on the interior of a building and are a good choice in areas with low seismic activity.

These systems are particularly water inefficient and often require constant irrigation due to the thin nature of the medium and its inability to hold water and provide a buffer for the plant roots.

Mat systems are not suitable for large installations or areas with high plant growth, as the mat can be ripped apart under the weight of the plants.

Mat media are better suited for small installations no more than eight feet in height where repairs are easily completed, and this is a significant consideration when planning a living wall project.

Structural media are growth medium "blocks" that can be manufactured into various sizes, shapes, and thicknesses.

These blocks have the advantage of not breaking down for 10 to 15 years and can be customized to have a higher or lower water holding capacity depending on the plant selection.

Structural media can also have their pH and EC's tailored to suit the specific plants used in the wall.

This makes them easy to handle for maintenance and replacement, as they don't break down like loose or mat media.

They can be made to have a higher or lower water holding capacity depending on the plant selection for the wall.

This versatility is one of the key benefits of using structural media in living walls.

Media-Free green walls don't require soil substrates, fertilizers, or reticulated watering systems.

These systems use a structural steel frame infilled with wire mesh, which is then attached to the façade of the structure, and plants are individually attached to this wire mesh.

The frames are offset from the supporting structure to allow airflow between the green wall and the supporting structure, resulting in additional cooling to the adjoining building.

This method results in green walls that are considerably lighter than other methods, and also require significantly less maintenance.

The risk of liquid migration into adjoining structural walls is eliminated.

Xeric plants like Tillandsias can be used in media-free systems because they absorb available atmospheric water and nutrients via trichome leaf cells, and their roots have developed to hold onto a support structure.

Tillandsias use a crassulacean acid metabolism to photosynthesize, and they have evolved to withstand long periods of heat and drought, requiring minimal maintenance.

Every three-to-five-years, any additional plant growth can be harvested to reduce weight, and these plant pups can be utilized for additional green walls.

Potential plant losses across any three-to-five-year period is minor as long as suitable species are matched to the climate of the green wall's location.

This method eliminates potential mold, algae, and moss problems that can plague other systems because of the lack of media and water.

Media-free screens can also be installed horizontally, and the first of these screens ever installed was for a 2023 installation on the rooftop of the City of Melbourne's Council House 2 building.
