Background/unmet need

Green roofs have the potential to retain storm water on the roof surface and lower the thermal loading on buildings. Green-roof technology could be especially beneficial in the American South and Southwest, where drought conditions are persistent. However, current commercial green-roof substrates perform poorly in these hotter climates, where drought is persistent and the substrates are unable to retain the proper amount of moisture.

Invention Description

Researchers at UT Austin have created a new green-roofing/wall growing media that is ideal for the harsh summer climates of the American South and Southwest. Years of studying how different soil media are affected in this region have allowed these scientist to create the ideal mixture that stands up to intense heat and drought conditions.


  • Better performance of green roofs/walls in the South and Southwest United States
  • Increases potential geographical distributions of green walls and roofs


  • Better water retention
  • High heat tolerance
  • Drought resistant
