Agreenroofis agreenspace created by adding layers of growing medium andplantson top of a traditional roofing system. This should not be confused with the traditionalroofgarden,where planting is done in freestanding containers and planters,located on an accessibleroofterrace or deck.
Greenroofsare promoted as a nature-based approach to mitigate various environmental issues and provide a variety of ecosystem services. However, establishing and maintainingplantsongreenroofscan indeed be challenging with unclear net benefits. This review exploresplantdiversity integration on extensivegreenroofs, emphasizing its ecological benefits, management challenges, and best ...
GREENROOFSGreenroofsare designed to retain, treat, filter, and transport rooftop runoff. The volume of water that will be retained determines the design. Additionally, the design must consider the load-bearing capacity of theroofstructure on which theplantswill be installed. Theroofmust be able to support the weight of theplants, soil, and captured water.Plantschosen will impact ...
GreenRoofComposition Agreena rooftop, contiguousroofis not simplyplantsplaced on but rather a highly-engineered, system of plantings designed to protect the structural integrity of the building while providing significant environmental, economic and aesthetic benefits.
Because of this, specific design strategies,plantselection, growing media and supplemental irrigationrequirementsare key considerations forgreenroofproject parameters to continue to evolve for the climate in the semi-arid and arid west.
Furthermore, visual representations like the one above help us fully grasp the concept of Green Roof Plant Adaptation Requirements.
Greenroofscan remove up to 50% of the annual rainfall volume that falls on theroof.Greenroofsremove precipitation through water retention and evapotranspiration. There are two types ofgreenroofs: Extensive - low-growingplantswith a thinner soil layer.
