In 2007, the City of Sydney developed a long-term strategic vision and plan for the future, Sustainable Sydney 2030. Building on the success of this plan, the City of Sydney are looking beyond the minimum 10-year lifespan to develop a vision for ‘Sydney 2050’ that is community led and informed by reliable research and technical advice. Planning for Sydney 2050 will look to the recently developed Resilient Sydney report which provides the first strategic direction for the city to increase its “ability to survive, adapt and thrive in the face of increasing global uncertainty and local shocks and stresses”.
A key direction of this report and of the planning for Sydney 2050 is to ‘live with our climate’. Within this, extreme heat is identified as the one of the primary challenges for Greater Sydney and addressing it requires collaborative action and policy to minimise the associated health risks and resource demands. Therefore, the purpose of this report is to provide urban overheating mitigation recommendations to support the strategic planning of Sydney 2050 based on in-depth research conducted by the Cooperative Research Centre for Low Carbon Living (CRCLCL) and the University of New South Wales (UNSW).
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
Financing the upfront costs of energy efficiency and renewable energy projects in buildings can be a significant barrier to the expansion of sustainable, low carbon buildings, despite this being a low-cost option on the carbon abatement curve. Systematic literature on...Read more
It has become increasingly important to study the urban heat island phenomenon due to the adverse effects on summertime cooling energy demand, air and water quality and most importantly, heat-related illness and mortality. The present article analyses the magnitude and the characteristics of the urban heat island in Sydney, Australia. Climatic data from six meteorological stations distributed around the greater Sydney region and covering a period of 10 years are used. It is found that both strong urban heat island (UHI) and oasis phenomena are developed.
Overheating of cities is causing serious energy, environmental and health problems and it has a serious impact on the whole economic and cultural life of cities. To counterbalance the impact of high urban temperatures several mitigation technologies have been proposed, developed and implemented.
This project was carried out by UNSW Sydney and Swinburne University in collaboration with government and industry partners. This report briefly outlines the achievements of the project, incorporating several previously published reports and case studies in addition to two new case studies in Parramatta and Macarthur Heights.
The main outcomes of the project include the following two online tools:
Local and global climate change increases the ambient temperature of cities by several degrees with important consequences on energy consumption, health and the economy. Advanced urban mitigation technologies contribute to decrease the ambient temperature and counterbalance the impact of urban heat islands. The present paper analyses and presents in a comparative way the mitigation potential of the known mitigation technologies using performance data from about 220 real scale urban rehabilitation projects.
