Global warming and climate change are among the most pressing challenges facing humanity today. Approximately 70% of cities are affected by these issues, with nearly all urban areas at risk. Large cities are responsible for more than 70% of global carbon dioxide emissions and consume 2.3 times the world’s energy, making urban strategies critical to controlling climate change. Rising urban air temperatures have prompted architects to explore innovative solutions, such as green facades, in both new and existing buildings. Vertical green systems are increasingly used to improve air quality and enhance environmental conditions around structures. This article introduces the main types of green walls and highlights their benefits for human health and the surrounding environment. The research methodology includes case studies, comparisons with conventional buildings, and surveys of building residents. The acceleration of global warming and climate change has made it imperative to adopt adaptive strategies. Utilizing vertical green spaces on buildings not only mitigates the heat island effect but also contributes to sustainable architecture and enhances the quality of life for residents.
