Urban overheating is causing serious energy and environmental problems. Furthermore, the exposure to high temperatures and heat stress at the urban scale is a frequent cause of reduced health and well-being in an urban environment. To counterbalance the impact of high urban temperatures, several mitigation technologies have been proposed, developed, and implemented worldwide. Monitoring of several large-scale urban projects involving the application of mitigation technologies has shown the possibility to decrease the peak ambient temperature of the precincts up to 2.5 °C. Analysis reveals that the magnitude of the overheating depends on many parameters including the layout and the characteristics of the buildings and open spaces, the type of the building and paving materials, the anthropogenic heat released by vehicle exhausts and building heating and cooling, land use, and climatic conditions, etc. This project performs analysis of Menangle Park precinct existing and future scenarios to evaluate the effectiveness of different mitigation strategies.
The results and conclusion have shown that:
