Vertical gardens and green walls are becoming essential tools for cooling dense cities and reducing the urban heat island effect. By integrating hydroponic systems and strategic plant selection, these installations lower building surface temperatures and improve thermal comfort for residents during heatwaves. Beyond temperature control, vertical forests like Milan's Bosco Verticale provide measurable environmental benefits, including carbon sequestration and the restoration of urban biodiversity. These systems offer a scalable way to introduce nature into cities where ground space for traditional parks is unavailable.
