Green roof or solar? Both is best

Australian first biosolar green roof study leads the way for climate resilient cities.

The benefits of combining solar panel installations with green roofs has been confirmed by new research, which demonstrates significant improvements in energy production, stormwater filtration and most surprisingly, a major increase in animal biodiversity.

The study, led by UTS researchers Peter Irga, Fraser Torpy and Robert Fleck set out to measure the advantages of green roofs in cities, and was supported by Lendlease and Junglefy.

Undertaken in Barangaroo in central Sydney, the researchers compared the conventional photovoltaic (PV) solar system on International House with a combined PV solar and integrated Junglefy green roof system (biosolar roof) on Daramu House over an eight-month period that spanned summer and winter.
