Green Roofs

After looking over the conceptual site plan drawing for the Academic and Student Affairs Building, I realized it was going to have a green roof.  Some of the benefits of green roofs include:
  • Reduce cooling loads on building by fifty to ninety percent.  With Blacksburg climate this won't play as much as a factor as it would in a hot/dry climate such as Arizona, but is still cost efficient.  Evaporative cooling is the cooling of air through the evaporation of water.  Both simple and cost effective.
  • Reduces storm water run off, using this water to irrigate the vegetation on the roof.
  •  LEED points and filtering of pollutants out of the rainwater.
Below is a picture of a building in Japan with a green roofs:

Detailed look at the green terraces. 
"Effluent follows the drainage system of a natural mountain. The system used as a base entails rainwater from the top floor (13th floor) permeating into the soil and following water paths, before permeating through to the step gardens on lower floors, before reaching the ground level."http://www.treehugger.com/files/2008/07/green-roofs-fukuoka-japan.php
