A living roof, or green roof, is a roof of a building that is partially or completely covered with vegetation and a growing medium (soil or another medium), planted over a waterproofing membrane.

A green roof can provide a cooling effect on the immediate surroundings, benefiting both the building and the area. Also, there is an insulating effect by the layer of soil, if used. Green roofs, if implemented widely in a city, could help reduce the heat island effect.[verification needed]

However, they typically require a stronger structure, particularly if soil is used. Thus any environmental advantages may be offset by the greater embedded energy of the structure. The insulating effect can be achieved more cheaply by other means.[verification needed] See Insulation. However, other forms of roof insulation will not have the same cooling effect on the immediate surroundings.

Suggested projects

  • Weigh up the environmental advantages and disadvantages of green roofs, comparing them with alternative designs.
