What’s the Most Effective Way to Incorporate Living Walls Indoors for Air Quality?

As our urban spaces expand, the need to incorporate the green into our grey cityscapes has never been more urgent. One solution gaining popularity is the use of living walls. These vertical gardens not only make a visual impact, but they also contribute positively to air quality, energy efficiency, and overall health and wellbeing. In this article, we will explore the most effective ways to incorporate living walls indoors.

Understanding the Concept of Living Walls

Before we delve into how to integrate this green innovation into your space, it’s important to understand what living walls are. These vertical structures, also known as green walls or wall plants, are systems designed to grow plants on walls. Living walls can range from simple panels of trailing plants to intricate designs of different species, creating a living piece of art.

Living walls are not just decorative; they also serve a purpose. They can improve indoor air quality, reduce energy costs by providing natural insulation, and even increase the level of humidity in the air, which can be beneficial during heating seasons. As a bonus, they can also contribute to your mental well-being by providing a relaxing, natural element in the otherwise concrete jungle.

How Do Living Walls Improve Indoor Air Quality?

The incorporation of living walls in indoor spaces presents an effective solution to improving air quality. Plants in living walls work as natural air purifiers. They absorb harmful pollutants through their leaves and roots, breaking them down into harmless substances and releasing oxygen in the process.

Studies by scholars have shown that plants can remove 87% of toxins in the air within 24 hours. As a result, the air inside a building with a living wall is fresher and cleaner. Additionally, the plants can help maintain humidity levels, providing a comfortable indoor environment and reducing the need for artificial humidifiers.

Designing Your Indoor Living Wall

When it comes to designing your indoor living wall, it’s crucial to consider the type of plants you want to incorporate, the available light, and the overall aesthetic you want to achieve. The right plant selection will ensure your living wall thrives while also effectively improving air quality.

Choose plants based on the amount of light your indoor space receives. Some plants, like ferns and ivy, do well in low light, while others, like succulents and certain herbs, require more sunlight. Also, consider plants that are known for their air-purifying qualities, like spider plants, peace lilies, and English ivy.

Consider incorporating an integrated watering system into your design. These systems can be as simple as a drip irrigation system that delivers water to each plant, ensuring they receive the right amount of moisture without overwatering.

Building and Maintaining Your Living Wall

Building a living wall may seem daunting, but with the right approach and resources, it can be a manageable project. There are various systems available on the market, from modular panels that you can easily attach to your wall to more complex setups that require professional installation.

Maintenance of a living wall is equally important as its design and construction. Regular watering, fertilizing, and pruning will keep your living wall looking its best and functioning optimally. The watering system you choose will play a significant role here, as it can automate the task and ensure consistent moisture levels.

The health of the plants on your living wall directly affects its efficacy in improving indoor air quality. Therefore, it is essential to keep the plants healthy and thriving. Monitor for signs of disease or pest infestation and treat promptly to prevent the spread to other plants on the wall.

Living Walls and Energy Efficiency

In addition to improving indoor air quality, living walls can also contribute to energy efficiency in buildings. They provide natural insulation, reducing the need for heating and cooling systems and thereby lowering energy consumption.

During the summer, the plants absorb sunlight, reducing the amount of heat that reaches the building’s interior. During the winter, they act as an extra layer of insulation, retaining heat inside the building. This can lead to significant savings on energy costs.

Moreover, living walls can absorb sound, creating a quieter, more peaceful indoor environment. This is especially beneficial in bustling urban areas, where noise pollution can be a significant issue.

Overall, incorporating living walls indoors offers many benefits. While improving air quality is a significant advantage, the added bonus of energy efficiency and aesthetic appeal makes living walls a compelling choice for individuals and businesses alike. So consider adding a touch of green to your walls for a healthier, more vibrant living or working space.

Incorporating Modern Technology with Living Walls

Today, with the rapid advancement of technology, it’s possible to incorporate living walls into our spaces in a more efficient and manageable way. Technology can help in the maintenance of these green walls, ensuring their health and, in turn, maximizing their air-purifying capabilities.

You might be wondering how technology comes into the picture. One example is the use of smart automated watering systems. These systems can monitor the moisture levels in the soil and water the plants as needed. This not only saves water but also ensures that the plants are neither overwatered nor underwatered. Both of these conditions can harm the plants and reduce their ability to purify the air.

In addition to watering, technological advancements can also help with lighting. For indoor living walls, artificial lighting might be necessary, especially if natural light is insufficient. LED grow lights can be used to provide the plants with the required amount of light. These lights consume less electricity and produce less heat than traditional lighting systems, contributing to energy efficiency.

Furthermore, technology can aid in monitoring the health of the plants. Apps and software can alert you to potential disease or pest problems, allowing you to react quickly and prevent further damage to your living wall.

Air Quality Monitoring and Living Walls

One of the main purposes of installing a living wall is to improve indoor air quality. However, to truly understand the effects of your living wall on air quality, monitoring is essential. By measuring parameters like carbon monoxide, particulate matter, and relative humidity, you can assess how well your wall is performing and make any necessary adjustments.

Several air quality monitoring devices are available on the market. Some devices can even be integrated with a smartphone or a home automation system, providing real-time updates on the quality of your indoor air. These devices can measure various air pollutants, including volatile organic compounds (VOCs), which can be emitted by certain building materials and can have health effects.

Living walls can help reduce these pollutants, improving the quality of your indoor air. By monitoring air quality, you can understand the impact your living wall is having and take steps to optimize its performance.


In conclusion, living walls offer a viable and effective solution to improve indoor air quality while enhancing the aesthetic appeal of our living or working spaces. They contribute to a healthier and more pleasant built environment, reducing air pollution and maintaining relative humidity at comfortable levels.

With the integration of modern technology, maintaining a living wall becomes a more manageable task. Smart watering systems, LED grow lights, and air quality monitoring devices can help ensure the health of your green wall and its efficiency in purifying the air.

As we continue to grapple with the challenges of urban expansion and environmental degradation, solutions like living walls become all the more critical. They represent a fusion of nature and technology, providing a sustainable way to improve our indoor environments. Whether at home or at work, incorporating a living wall can bring a touch of nature indoors, promoting health, well-being, and a sense of tranquility amidst our busy lives.
