Environmental benefits of Green Roof

Environmental benefits
A modern green roof (California Academy of Sciences). Constructed for low maintenance by intentionally avoiding many native plant species, with only the hardiest surviving varieties selected for installation on the roof.

Green roofs are used to:

  • Reduce heating (by adding mass and thermal resistance value)

A 2005 study by Brad Bass of the University of Toronto showed that green roofs can also reduce heat loss and energy consumption in winter conditions.

  • Reduce cooling (by evaporative cooling) loads on a building by fifty to ninety percent
  • especially if it is glassed in so as to act as a terrarium and passive solar heat reservoir — a concentration of green roofs in an urban area can even reduce the city's average temperatures during the summer
  • Reduce stormwater run off  — see water-wise gardening
  • Natural Habitat Creation  — see urban wilderness
  • Filter pollutants and carbon dioxide out of the air which helps lower disease rates such as asthma — see living wall
  • Filter pollutants and heavy metals out of rainwater
  • Help to insulate a building for sound; the soil helps to block lower frequencies and the plants block higher frequencies
  • If installed correctly many living roofs can contribute to LEED points
  • Increase agricultural space
