Sydney trials measures for a cooler city

Keeping-temperatures-lower-in-the-growing-city-is-key_157_73672_0_14100167_300Sydney is trialling a bold new strategy for reducing temperatures in urban areas, which could boost liveability in the rapidly thriving city.

The City of Sydney is installing lighter-coloured pavement in the inner-city suburb of Chippendale, which includes a 600 square metre section on Myrtle Street. The process will involve filling open grade asphalt pavement with concrete slurry, lightening the colour of the pavement, according to a June 17 council statement.

The streets will be monitored over the the following months, looking at whether or not temperatures drop along the lighter areas of the streets. If the trial proves successful, it could be expanded to other parts of Sydney, and even to other parts of Australia eventually.

Independent sustainability expert Michael Mobbs praised the idea behind the trial.

“Materials such as concrete and cement store more heat than natural surfaces, absorbing it during the day and releasing it at night, which can contribute to hotter urban areas,” Mr Mobbs told the council.

“Black-coloured roads and a lack of tree cover can increase the heat of our cities by up to eight degrees. Lighter-coloured pavements may result in lower energy bills for surrounding buildings.”

The success of the trial thus far has the potential to doubly benefit Sydney residents. Not only might this bring down energy costs for surrounding neighbourhoods, but lower temperatures in the already sweltering city will be a tangible improvement to the lives of Sydneysiders. It wouldn’t be surprising if this further raises the city’s profile for home buyers.

Temperatures in the city are expected to rise significantly due to climate change as well as the city’s accelerating growth which will see millions more people added to the city.

Lord Mayor Clover Moore pointed out the city was also increasing tree canopy by 50 per cent to keep buildings cool.

A more habitable Sydney is likely to result from these measures, which is good news for owners of Sydney property.
