Council's cool concept to help reduce heat island effect

Campbelltown Council is investigating opportunities to trial a new 'cool pavement' idea which could reduce temperatures around the city.

Traditional pavement materials add to the urban heat island effect which raises temperatures in populated areas, but cool pavements work in the opposite way, and can reduce the heat island effect.

Council director of city growth and economy Rebecca Grasso said the council was exploring avenues to introduce cool pavement in the area.

"Council is investigating opportunities to partner with universities and other western Sydney councils to trial cool pavements within Campbelltown this summer," she said.

"The council maintains an increasing number of footpaths and cycleways which require regular replenishment.

"This provides an opportunity within the Reimagining Campbelltown City Centres framework to explore new technologies that reduce the urban heat island effect and create more sustainable and resilient public infrastructure."

Traditional pavements, including concrete and asphalt, typically cover 25-50 per cent of the urban landscape, the latest council business papers revealed, and can reach peak summer surface temperatures well above 60 degrees Celsius.

Ms Grasso said there were a number of positive aspects to cool pavement technology.

"Cool pavements are typically lighter in colour, radiate heat more efficiently and are permeable, allowing water to drain and evaporate which also helps to maintain surrounding vegetation," she said.
