This document provides practical guidance for built environment professionals and regulatory agencies seeking to optimise development projects to moderate urban microclimates and mitigate urban heat island effects in major urban centres across a range of climates in Australia .
The emphasis is on the public realm, and the scope is project-focused. The three dimensions which contextualise the effectiveness of urban cooling strategies in this Guide are urban form, climate type and the nature of intervention. This 3D matrix provides the framework for the Guide, in terms of both process (methods) and product (the design outcomes).
This project covers urban heat mitigation strategies in climate zones relevant to Brisbane, Sydney, Parramatta, Canberra, Melbourne, Hobart, Adelaide, Perth, Darwin and Cairns. The range of urban typologies include the dense inner city, middle ring and outer suburbs. The focus for design intervention will include streetscapes, plazas, squares and malls. Urban surface properties, vegetation cover, shading and orientation are key variables. Interventions cover both active (e.g. misting systems and operable awnings) and passive systems (street trees, green roofs/walls, water bodies, cool roofs and façades).
This urban cooling guide draws on data from the three- year Urban Microclimates project at the Cooperative Research Centre for Low Carbon Living, and cross- references the CRC LCL Microclimate and Urban Heat Island Decision-Support Tool project. It also benefits from relevant research at the CRC for Water Sensitive Cities.
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
Transportation planners are often looking for efficiency in transportation but this article in Science Advances has also identified that resilience is an important city design feature. Planning for when disruptions occur can help to avoid city gridlock.Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
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).
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.
Precipitation is a relevant climatic variable for building and urban design in hot climates, because of its potential to naturally mitigate heat excess in buildings and cities by evaporative cooling; and as a primary source of water to artificially reproduce this cooling mechanism, particularly in the humid tropics and subtropics.
Urban spaces are experiencing warmer microclimates as the combined result of climate change and the Urban Heat Island (UHI) effect. While climate change projections indicate a likely increase of 2°C in Australia by 2070, an additional heat load of 10°C exists in the built environment.
