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 strategies and techniques which can be applied to Australian cities. This review found that strategies can focus on:
- indoor air temperature reduction, including green roofs and vertical greening systems as well as cool roofs and high albedo materials.
- outdoor air temperature reduction including green spaces (such as ground vegetation, trees, and forests), blue spaces (such as lakes and rivers) and solar canopy (mainly applied to improve outdoor thermal comfort).
In many cases, a combination of strategies will be required.
