Effect of Green façade on Enhancement of Indoor Air Quality

This article explores the benefits of green facades in improving indoor air quality (IAQ) and their potential impact on energy efficiency. Green facades, also known as living walls or vertical gardens, are vertical structures covered with plants that can be installed both indoors and outdoors. They have gained attention in the field of sustainable architecture due to their ability to provide multiple advantages, including enhanced IAQ and energy efficiency. The research presented in this article is based on a comprehensive review of existing literature, real-world data, and simulation tools. The findings highlight the significant role of green facades in air purification, the reduction of harmful pollutants, and the overall well-being of building occupants. Green facades act as natural insulators, minimizing heat absorption in the summer and heat loss in the winter, thus reducing the energy needed for cooling and heating a building. The article also discusses the various types of green facades, such as direct greening, indirect greening, and living wall systems, and their potential applications in different climate conditions and building types. Additionally, it provides a visual representation of the process by which green facades contribute to improving IAQ, including the absorption of carbon dioxide and harmful air pollutants. The effectiveness of green facades in improving IAQ and energy efficiency remains significant. Incorporating green facades into smart building design can contribute to creating healthier and more sustainable indoor environments, reduce air pollution, and enhance the well-being of building occupants.
