Green roofs are layers of vegetation planted on the rooftops of buildings. They help to reduce energy costs by providing insulation, which keeps buildings cooler in the summer and warmer in the winter. Additionally, green roofs can manage stormwater by absorbing rain, reducing runoff, and improving urban air quality.
These roofs can also support biodiversity by providing habitats for birds, insects, and other wildlife. They are often designed with various plants, including sedums, grasses, and wildflowers, which can thrive in rooftop conditions. Overall, green roofs contribute to sustainable urban development and enhance the aesthetic appeal of cities.
