The Essential Guide To Green Roof Systems

By Nova No comments

Green roofs 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 layer, a drainage-storage foil, a filtering felt layer, a green roof substrate, and a finishing layer of the plant. Green roofs are divided into two types: intensive and extensive green roofs. Based on the type of green roof, the flora, substrate, and other layers may differ.

Benefits Of Green Roof  

Vegetation decreases air pollution and greenhouse gas emissions by storing carbon in the form of dry deposition, confiscation, and storage green roof systems reduce the air pollution and greenhouse gas emissions connected with energy production by reducing the demand for power in buildings. Furthermore, because ground-level ozone is created more easily at high temperatures, green roofs inhibit the generation of ground-level ozone by lowering the atmospheric temperature.

Particulate and gaseous pollutants such as nitric oxide, sulphur dioxide, carbon monoxide, and ground-level ozone can be removed by green roofs. According to research, a green roof with a surface area of 93 square metres can remove around 40 kilogrammes of particles from the air in a year, producing oxygen and eliminating carbon dioxide from the environment. For example, 15 cars emit around 40 kg of particles in a year of driving.  Green roofs in urban areas minimise and slow down rainfall runoff. Green roofs’ plants and soil, as well as traditional green areas, absorb water that would otherwise be wasted.
