This project investigates the characteristics of the local climate in the CBD area of Alice Springs, NT. It identifies hot spots in the city to develop and evaluate appropriate local climate mitigation scenarios such as cool materials, urban shading devices, water-based technologies, greenery and tree planting.
One of the most documented climate phenomena is the urban heat island (UHI) effect, namely the local overheating in the built environment, with higher ambient temperatures than in the adjacent surroundings. This is documented for hundreds of cities around the world including major cities in Australia and it adds to and interacts with global climate change. The inner area of the CBD of Alice Springs, a remote town in Australia’s Northern Territory, is affected by local overheating and the urban heat island effect adds to the already high temperatures in the area, which impacts thermal comfort, energy consumption and health, with serious consequences on the local economy. The specific objective of this project is decreasing the ambient temperature in Alice Springs by identifying hot spots in the city, developing and evaluating appropriate local climate mitigation scenarios (five mitigation scenarios involving UHI mitigation strategies such as use of reflective materials for buildings and pavements, street shading, windbreak and evaporative systems), and propose optimum solutions. Advanced simulation techniques have been used to quantitatively evaluate their UHI mitigation impact.
