GREEN ROOF DEFINITIONS
- A ‘Green Roof’ is a vegetated space that is structurally integrated on top of a man made structure. The word ‘roof’ in this context refers to any continuous surface designed for the protection of inhabitants from the elements, whether open or closed on the sides. The vegetated space may be below, at, or above grade; located on a podium deck, a ‘sky garden’ on an intermediate floor level, or at the very top level of the building; but in all cases the plants are not planted in the ground.
There are two main types of green roofs:
- Extensive Green Roofs, that are lightweight, have a narrow plant range, and are geared for low maintenance; and
- Intensive Green Roofs that have deep soils, a wide plant choice and are geared for recreational use by human beings.
