Growing population development and the covered areas by buildings in metropolitan regions resulted in less suitable living conditions and reduced quality of life for city dwellers, as well as affecting climate change, natural disasters, and reducing sustainability on a wider scale. In the larger picture of sustainable development, the current concept of green building was formed as one of the solutions for modern society to tackle these difficulties, which varies in so many methods from the building trend that has been prevalent for years. Green roofs are among the sections of green building that modern architecture has developed to discover sustainable solutions for modern construction.
green roof systems are a new green building technology that consists of a vegetative covering on the roof. They are made up of multiple layers, including a protective felt covering, a drainage-storage foil, a filtering felt layer, a green roof base, and a final layer of the plant. Green roofs are divided into two types: extensive and comprehensive green roofs. Based on the type of green roof other layers may differ.
Benefits Of Green Roof
Green roofs can minimise the amount of energy required for building heating and cooling by absorbing and storing enormous amounts of heat when they are wet, reducing temperature variations. During the winter, these insulating effects imply that the building emits less heat, reducing the demand for heating. Green roof flora decreases the temperature of the rooftop and the surrounding air in the summer, reducing the need for cooling electricity.
