And fervent overflow of drains. Can you imagine a whole country full of green buildings?  ]]> 2016-05-04 06:44:32 UTC https://padlet.com/covenc2/greenroof/wish/109145492 green roof covenc2 https://padlet.com/covenc2/greenroof/wish/109146267 2016-05-04 06:50:04 UTC https://padlet.com/covenc2/greenroof/wish/109146267 green roofs covenc2 https://padlet.com/covenc2/greenroof/wish/109146340 2016-05-04 06:50:45 UTC https://padlet.com/covenc2/greenroof/wish/109146340 Brief description  covenc2 https://padlet.com/covenc2/greenroof/wish/109146434

Waste Diversion

  • Prolonging the service life of heating, ventilation, and HVAC systems through decreased use
  • You can use recycled materials in the growing medium

Stormwater Management

  • 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.

  • Green roofs reduce the amount of stormwater runoff and also delay the time at which runoff occurs, resulting in decreased stress on sewer systems at peak flow periods.
