You Can Combine Them in a Biosolar Roof, Boosting Both Biodiversity and Power Output

Scientists in the Netherlands have assessed how the so-called blue-green roofs can help reduce the operating temperature of rooftop PV panels and have found they provide a significant cooling effect.

Researchers found that vertical green-living walls can save up to 20 per cent of the energy used for air circulation in closed offices and spaces.

Two identical office buildings side by side in Sydney's Barangaroo provided a perfect opportunity for solar energy researchers to test a long-held hunch.
