Today, with the advancement of technology, industrialization, and scientific progress, life has moved toward mechanization. Attention to the environment, energy resources, and air pollution has become a significant concern of the present era. Creating interactive green roofs and walls is a way to make cities more sustainable, and one of the modern solutions to urban problems, reducing air pollution through the creation of green spaces. Green walls have tremendous potential in terms of energy savings and increasing the lifespan of buildings, which are among the side benefits of this approach. The use of vertical green systems, known by various names such as vertical gardens, green walls, energy storage, building facade beautification, and urban form enhancement, is gaining popularity. Green architecture is also one of the new trends and approaches in architecture that has attracted many contemporary designers and architects worldwide in recent years. This architecture, which originates from sustainable development concepts, seeks compatibility and harmony with the environment as one of humanity's essential needs in today's world. The research method in this article is descriptive-analytical. First, by reviewing the theoretical background, various types of green walls are named. Then, the type and extent of the effects of green walls on building cooling and heating are analyzed and explained based on the collected data. The goal of creating green buildings is to improve air quality, prevent energy loss used for cooling and heating, and reduce the negative impacts of construction on the environment. This results in the design and use of green walls in the building's exterior or interior spaces as one of the strategies toward implementing green architecture. In fact, a green fence goes beyond being just a plant-covered facade; it is a structure that, although having a relatively simple function, requires precise design of its components and the correct selection of plants to achieve the goals of reducing cooling and heating costs, mitigating the urban heat island effect, and increasing wind resistance.
