Green roofs, green walls and rooftop gardens have a vast potential to address many of the fundamental challenges facing modern urban living.

They are not just beautiful, enjoyable and distressing spaces, but they also serve many purposes, such as absorbing rainwater, providing insulation for a building, decreasing temperature of surounding area, creating a habitat for wildlife, increasing amenity and green space in city…

Environmental benefits

  • Reduce heating (by adding mass and thermal resistance value).
  • 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.
  • Natural Habitat Creation.
  • Filter pollutants and carbon dioxide out of the air which helps lower disease rates such as asthma.
  • 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.
  • With green roofs, water is stored by the substrate and then taken up by the plants from where it is returned to the atmosphere through transpiration and evaporation.
  • Green roofs not only retain rainwater, but also moderate the temperature of the water and act as natural filters for any of the water that happens to run off.
