Researching the benefits of demonstration green roofs across Australia

In this project we are investigating and developing solutions to cultural, community and horticultural barriers to green roof construction.

With expertise in green infrastructure, psychology and business, our interdisciplinary research team is investigating:

  • the effectiveness of demonstration green roofs in overcoming barriers to uptake
  • proven plant palettes for different green roof build-ups
  • maintenance needs of different green roof build-ups for new implementation guidelines
  • which green roof plants are aesthetically attractive to a wide range of people
  • vegetation characteristics that increase emotional wellbeing.
