Green Roof Sustainability

A green roof significantly reduces the need for air conditioning in summer and provides insulation in the winter.

Green roof sustainability.

The increased urbanization of towns and cities has resulted in less green space and more impervious surfaces. Green roofs also contribute to the sustainability of a building. Decreasing stormwater runoff on average of 40 to 60 keeping runoff out of local sewer systems and reducing wear and tear along with potential damage that can lead to contamination. Green roofs with grass help reduce the temperature inside a sustainable building in summer and grass roofs make eco homes warmer in winter.

They mitigate the urban heat island effect by covering heat attracting roofs with vegetation that absorbs sunlight radiation. It should also be light weight resistant to decomposition and compression and physically and chemically stable. Green roof economics benefits costs npv net present value benefits costs rinaldi buffam et al. Additionally this natural protection against extreme heat enables green roofs to last twice as long as traditional rooftops.

A green roof s plants remove air particulates produce oxygen and provide shade. That is how roof top gardens dramatically lower air conditioning and heating costs. In prep assumes a 40 year lifespan of the green roof and a 20 year lifespan of a conventional roof model based in cincinnati with cso s present largest cost of green roof is related to installation but roof replacement costs are reduced. Green roofs improve the sustainability of their surrounding areas by.

Green roof growing medium is composed of mineral aggregates and only a small amount of organic material. The insulation in the winter will depend on the amount of moisture in the various layers. Green roofs help reduce the urban heat island effect a condition in which urban environments absorb and trap heat. Ginkgo sustainability is committed to being a leader in the living roof and living wall industry.

Associate director of sustainability sam crowl said green roofs provide a lot of benefits and noted that the schoonover space was always designed to be a green roof. Precipitation generally runs off the roof of a building into gutters and flows into a storm sewer. A green roof also helps control storm water runoff and retention. We should have energy savings we should have a better insulator and we re dealing with storm water in a better way crowl said.
