Urban heat study to guide the cooling of Darwin

The Northern Territory Government has released an urban heat study that will guide steps to cool the city of Darwin and make it more liveable for residents and attractive to tourists throughout the year.

The study, undertaken by a research team at the University of New South Wales Faculty of the Built Environment with a grant from the NT Government, maps temperatures across the CBD using thermal imaging and drone monitoring.

The study found Darwin's streets, parking lots, roofs and pavements have very high surface temperatures, ranging from 45-67C. Areas that are particularly hot are the Post Office carpark, the Supreme Court carpark, the Bus Terminal and Cavenagh Street.

The Study also identifies cooling methods such as reflective materials to cool pavements and roofs, street shading, greenery, and evaporative water systems.

Chief Minister of the NT, Michael Gunner, said that to make Darwin walkable and liveable the temperature needed to be reduced generally by 2C and in hot spots by 4C. Earlier this year he headed a delegation to Singapore to look into urban green design concepts that have been successfully adopted by a city with a similar climate to Darwin.

Further mapping of temperature over a 12 month period will be undertaken to continue to build a consolidated picture of temperature, including a small number of weather stations to be installed through the CBD.
