Quick answer：Roof greening on top floors refers to the process of planting vegetation on the roofs of buildings. This practice is becoming popular for its environmental benefits, such as reducing urban heat island effects, improving air quality, and providing additional green space. An 'effect diagram' would be a visual representation showing how the roof will look after greening, often used for architectural design and planning purposes.
