Countries across the globe are likely to face significant challenges in coming years that will test the resilience of their cities. However, there is often a lack of proactive evidence-based analysis of available options and their outcomes as well as indicators of success or progress.
Important research is looking at counteractive measures to urban heat island effect from the best materials to reflect urban heat to the best technology and urban design to keep us cool. What we can do now is make our cities, where the majority live, smarter, healthier and increasingly more liveable.
Buildings are major consumers of energy for heating and cooling. The number of buildings is growing rapidly with demand for energy. To reduce consumption, governments worldwide have implemented codes, standards, and building practices.
The Building Sustainability Index (BASIX) assessment tool estimates the operational energy consumption and GHG emissions from new residential developments based on information available at the building design stage. However, post-occupancy energy consumption can be different from the estimated figures at the design stage.
At present, building scale energy efficiency is often limited to the design stage; therefore, the post occupancy energy efficiency of dwellings rarely gets reported. Australian households receive quarterly energy bills; however, these bills, which show aggregated energy consumption, are not helpful in understanding the breakdown of energy usage that would...
Maintaining indoor thermal comfort is crucial for the health and productivity of building occupants. Building envelope plays a major role in influencing the impact of outdoor climate and controlling the indoor thermal conditions.
Sustainability assessment tools aim to promote high sustainability outcomes in residential buildings, ensuring less consumption of water, energy and less emission of greenhouse gases. However, existing literature often presents variations between the estimated outcomes from the assessment tools and actual outcomes after building occupation.
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.
This strategy provides 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).
