Environmental Benefits Of Green Roof To The Sustainable Urban Development: A Review
With rapid growth of population and the increasing demands for higher living standards, the development of urban infrastructures and buildings are likely will increase the impervious surfaces in the river basin. Green roofs have become a popular strategy in the sustainable urban development strategies in recent decades. Green roof is a viable means of increasing the amount of vegetation in urban cities, where the open space at ground level is limited but roof tops are largely unused yet remain impervious and contribute to stormwater runoff. This paper is aimed to review comprehensively the types, components and environmental benefits of green roofs to the sustainable urban development. Generally, green roofs provide many benefits such as reduce energy consumption by decreasing cooling and heating loads, provide amenity and aesthetic value, increase building values, improve stormwater runoff mitigation, lower air temperatures, enhance urban air quality, assist in urban stormwater pollutant removal, reduce noise in urban environments and mitigate urban heat island effects. This paper also reviewed the development and application of green roofs in different countries. In conclusion, more implementation of green roofs in the urban city should be promoted in order to ensure the sustainability of the urban development.
