Green Roof Sustainability

It should also be light weight resistant to decomposition and compression and physically and chemically stable.

Green roof sustainability.

Green roofs help reduce the urban heat island effect a condition in which urban environments absorb and trap heat. They mitigate the urban heat island effect by covering heat attracting roofs with vegetation that absorbs sunlight radiation. Green roofs with grass help reduce the temperature inside a sustainable building in summer and grass roofs make eco homes warmer in winter. Additionally this natural protection against extreme heat enables green roofs to last twice as long as traditional rooftops.

A green roof significantly reduces the need for air conditioning in summer and provides insulation in the winter. Green roofs reduce carbon dioxide in the atmosphere by storing it in plant tissue. The insulation in the winter will depend on the amount of moisture in the various layers. Green roofs improve the sustainability of their surrounding areas by.

Precipitation generally runs off the roof of a building into gutters and flows into a storm sewer. 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. We should have energy savings we should have a better insulator and we re dealing with storm water in a better way crowl said.
