Roof greening cooling effect

Quick answer：

Roof greening refers to the practice of planting vegetation on roofs. It can effectively reduce the urban heat island effect, improve air quality, and provide insulation to reduce cooling energy consumption in buildings. The cooling effect is achieved through the evapotranspiration of plants, which cools the air, and the reflective properties of green roofs that reduce the absorption of solar heat. This method is increasingly being adopted in urban planning and sustainable architecture.
