Green Roof System

Urbanization has promoted fast urbanization with high surface temperature, stormwater runoff, and consumption of energy in cities. Traditional concrete roofs trap too much heat and also contribute to urban heat island effect. This paper is directed towards the design and analysis of a Green Roof System as a green solution to the present-day buildings. The system comprises of several layers such as waterproof membrane, drainage layer, filter fabric, light weight growing medium, and appropriate vegetation. The approach was site selection, structural load analysis, selection of materials and plants selection, and performance testing. It was observed that the green roof had lower surface temperatures than a normal roof, and stored more rainwater that otherwise would have been washed away in rainfall. Structural safety and adequate conditions of growth of the plants were checked by soil and load checks. The findings show that the green roofs have a beneficial effect on the thermal insulation, energy consumption, air quality, and environmental sustainability. That is why green roof systems can be regarded as a solution to environmental-friendly and sustainable urban development. .
