This guide focuses on the use of green infrastructure (GI) to mitigate urban heat. GI is an effective means to minimise heat accumulation in the urban environment as it shades hot surfaces, increases evapotranspirative cooling and modifies wind patterns The guide provides advice on spatially strategic ways to reduce urban surface temperatures across Greater Melbourne using increased cover of GI. Surface temperatures are an excellent target for mitigation by GI because sun exposure is a key driver of increased urban surface temperatures, and GI reduces this exposure through shading (e.g. trees) or covering these urban surfaces (e.g. green walls). Green infrastructure is an effective and socially appealing means to minimise heat accumulation in the urban environment. It maximises cooling by vegetation and delivers numerous other environmental and social benefits, with significantly less energy use and greenhouse gas emissions than alternatives such as air conditioning.
