The Role Of Extensive Green Roofs In Sustainable Development

Additionally this natural protection against extreme heat enables green roofs to last twice as long as traditional rooftops.

The role of extensive green roofs in sustainable development.

Therefore the focus of this review is primarily on extensive green roofs. This can play a role in reducing greenhouse gas emissions and adapting urban areas to a future climate with warmer summers. In natural areas much of the rain. A green roof s plants remove air particulates produce oxygen and provide shade.

Green roofs absorb heat and filter the air keeping the temperature low getter 2006. The technology addresses a wide array of environmental issues associated with urbanization. Green roofs are lightweight engineered rooftops designed to promote the growth of vegetation while protecting the structural integrity of the roof. Extensive roofs are much more common than deeper intensive roofs.

Environmental and human health benefits of green roofs include air purification urban heat island amelioration lower building energy costs increased urban biodiversity reduced stormwater runoff and improved stream water quality. The benefits of green roof show that it plays an important role in making cities safe sustainable and resilient to climate change. Before green roof technology can be incorporated into urban agriculture on a larger scale installation costs must be reduced roof weight limitations should be assessed and appropriate management practices should be developed which will ensure that the benefits of green roofs such as energy savings and storm water management are still provided to urban communities. Green roofs contribute to the sustainability efforts of an organization through.

In addition green roofs play a critical role in improving the urban environment by enriching the biodiversity delaying the storm peak to the drainage system diminishing the runoff quantity purifying the air pollutants as well as the runoff quality. Before human development began dis turbing natural habitats soil and vegetation constituted part of a balanced ecosystem that managed precipitation and solar energy ef fectively. So if the roofs are made green by vegetating it will act a major role in mitigating the uhi effect. Green roofs help reduce the urban heat island effect a condition in which urban environments absorb and trap heat.

Conserving energy by insulating the building and mitigating thermal heat gain which reduces the need for heating and cooling. Green roofs can also help reduce the distribution of dust and particulate matter throughout the city as well as the production of smog.
