What is one benefit of a green roof?

A green roof provides benefits primarily through its ability to insulate buildings and reduce heat absorption. The layer of vegetation and soil on a green roof acts as an effective barrier against temperature fluctuations, helping to keep buildings cooler in the summer and warmer in the winter. This results in lower energy costs for heating and cooling, which makes green roofs a sustainable design choice.

Additionally, the vegetation on a green roof helps to mitigate the urban heat island effect by absorbing sunlight rather than reflecting it, which in turn reduces the ambient temperature in urban areas. This feature is essential for promoting energy efficiency and environmental sustainability in urban landscapes. The correct choice captures the essence of these benefits and highlights the roles of green roofs in modern landscape architecture practices.
