GREEN structural Design
Green structural design comprises green roofs and green walls. These systems can be considered an unconventional form of open space that offers visual relief from the metal
and concrete of our dense urban areas, while at the same time providing stormwater
and pollution management benefits, habitat, and reduction of the heat island effect.
There are two type of green roofs – Intensive and Extensive. Intensive green roofs are
rooftop gardens that include spaces for humans to walk and relax. Extensive green
roofs have a thin soil profile and typically cover the entire roof surface. As a result, they
are not meant to be walked on. Extensive green roofs provide greater overall ecological
benefits primarily because they do not require irrigation.
Roofs with Green Structural Design
Like rooftop gardens, foliage covered walls have been used for centuries to add to the
aesthetics of designed open spaces. The new moniker, “green walls”, reflects the growing awareness that vegetated walls offer significant environmental benefits, particularly with respect to pollution reduction. Green walls are even beginning to be incorporated into building interiors in order to ameliorate the “sick building” effect.
Both green roofs and green walls can be used to provide sensory continuity between
more traditional open spaces. They can also serve as habitat patches and corridors for
birds and invertebrates
