The urban heat island (UHI) effect in which urban areas exhibit higher temperatures than the surrounding rural or suburban areas is well documented in hundreds of cities around the world including major cities in Australia.
The Government commissioned the University of New South Wales (UNSW) to conduct a study of inner city heat, humidity and wind movement. The study used thermal imaging and drone monitoring to map the city’s temperatures.
The initial report summarises the UNSW investigation of the characteristics of the urban heat island of Darwin, NT, identifying hot spots in the city, developing and evaluating appropriate UHI mitigation scenarios and proposing optimum UHI mitigation solutions that could be tailored for the city of Darwin.
Some of the recommendations to achieve a cooler inner city include greening and shading and new-generation paint and paving products. Further mapping of temperature over a twelve month period will be undertaken to continue to build a consolidated picture of temperature, hotspots and mitigation technologies.
