As the world increasingly focuses on sustainable and eco friendly building practices, facade architecture plays a crucial role in enhancing the environmental performance of buildings. This article explores the environmental function of external green elements in faca de architecture, such as living walls, vertical gardens, and green roofs. It high lights the benefits of these elements in terms of energy efficiency, air quality improvement, and biodiversity enhancement. By acting as natural insulation, external green ele ments reduce heat transfer and contribute to energy savings. They also help reducing air pollution by capturing dust particles and filtering pollutants, resulting in fresh and healthier urban environments. Additionally, these green elements create habitats for wildlife, promoting biodiversity within the built environment. The article a ddresses implementation considerations and challenges, offering recommendations for architects, designers, and building owners interested in incorporating external green eleme nts into their facades. By harnessing the potential of external green elements, f acade architecture can contribute to sustainable and environmentally responsible building practices, creating a greener and healthier future for urban spaces.
