A team from the University of Technology, Sydney, believes to have made a breakthrough in roof technology, creating a roof surface that stays cooler than the ambient air around it – even in hot Australian summers.
The development is a result of a study by Dr Angus Gentle and Emeritus Professor Geoff Smith from UTS. They reported the results, said to be 11 degrees colder than a state-of-the-art white roof, from a ‘coated polymer stack’ – a combination of specially chosen polyesters on a silver layer.
The results is believed to have major implications for reducing the severity of the heat island problems in urban areas, as well as helping eliminating peak power demand from air-conditioning.
The work has been supported by an Australian Research Council Discovery Project grant. Thanks for keeping Australia cool, and clever, UTS.
