6. Conclusion
Thermal performance of green roof system was measured in this study by developing a CFD model for a sub-
tropical climate in Queensland, Australia. Standard
turbulence model was used to develop the model.
The impact of air temperature was assessed on the room cooling performance using simulation. The simulation
result shows a minimum temperature reduction of approximately 0.95˚C in the room. The developed model was
validated at different points of the room with the measured data, and only 1.7% temperature variation was found
between numerical result predicted by Fluent and the experimental result. Further investigation is being under-
taken in this study.
