Rooftop greenery, also known as green roofs or living roofs, involves the application of vegetation to roofs. These installations not only serve aesthetic purposes but also provide environmental benefits such as improved energy efficiency, stormwater management, and habitat creation for urban wildlife. A 'large-scale rooftop greenery rendering' refers to a visual representation of a roof covered with extensive vegetation, often used in architectural design or urban planning to showcase the potential of green roofs.
