£1.5M canopy to protect Darwin from sun's rays

Ptm group

Work has begun on a £1.5M cooling canopy with vines, lighting and misting systems to combat rising temperatures in a major Australian city.

The 55m long timber and steel frame will let citizens enjoy the shade in Darwin, which often breaches temperatures of 30C. Surface temperatures of 60C have been recorded and the city expects to feel the heat as global warming increases pressure on its infrastructure.

Australian construction firm PTM Group is building the green cooling canopy in Darwin’s central business district until October.

Timber beams and vines will cover a 22m wide steel structure with high pressure misting systems further cooling the street, while an LED mod lighting system will provide tropical ambience, according to PTM Group.

It is one of five heat mitigation trials commissioned by the Northern Territory Government (NTG) over the next 18 months.

Other trials will see reflective paving surfaces, traffic islands offering shade for traffic and trees covering street corners from the sun.

Heat mitigation studies commissioned by the NTG used thermal imaging and drone monitoring to map Darwin’s humidity, heat and wind movement.

The trials form part of the Darwin City Plan, a 10-year plan between the NTG, the City of Darwin and Charles Darwin University to help Darwin stay pedestrian-friendly despite steadily rising temperatures associated with climate change.
