Green roof
The roof area is split into 7 zones: sedum, wildflowers, perennials/meadow, brown roof, a lightweight tree pit, a climber wall and a living wall. The roof also includes 6 experimental beds for green roof design research purposes.
This all sits on a multi-layered floor with a drainage underlayer that collates the excess water from the roof and directs it to the central irrigation tank. All zones are monitored and are automatically watered as needed from the irrigation tank. The weight and retrofit considerations were an essential factor in the design of this roof.
