Low weight low capital cost low plant diversity and minimal maintenance requirements.
Green roof design criteria.
Additional standards under development include performance standards for the multiple functions of growing media.
Green roofs for healthy cities works to develop standards in support of the further development of the industry.
The two basic types of green roof systems extensive and intensive are differentiated mainly by the cost depth of growing medium and the choice of plants.
Green roof design criteria structural capacity of the roof.
Completes thorough a project study of every installation to determine the most appropriate.
The green roof system.
Green roofs can be limited by the additional weight of the fully saturated soil and plants in terms of the physical capacity of the roof to bear structural loads.
The roofs are designed so that water drains vertically through the media and then horizontally along a waterproofing layer towards the outlet.
Design criteria for green roofs design criteria for green roofs green infrastructure.
Extensive green roofs are often not accessible and are characterized by.
Green roofs consist of a series of layers that create an environment suitable for plant growth without damaging the underlying roof system.
