Green roofs are plants and vegetation growing on a
roof. They are sometimes known as living roofs and can
contain a variety of different plants including (but not limited to) sedum/succulents, shrubs, grass and New Zealand native plants.
Green roofs contribute to healthy cities and are the
logical choice when considering green building design in urban areas.
They benefit the environment in a number of ways:
• they manage stormwater runoff by retaining rainwater
• they remove CO2 from the air and release oxygen
• they reduce the amount of heat absorbed from the sun and then released by buildings, back into the environment ("urban heat island effect")
• they insulate buildings by keeping the heat in during
the winter and the heat out during the summer
• they enable a building to merge into the landscape
• they encourage biodiversity within the urban environment
