Urban Heat

In Australia, 89% of Australians live in urban areas. The liveability and resilience of urban areas is therefore of critical importance but is under significant threat from increasing temperatures; particularly the number of extreme hot days and heatwave events. A key driver of urban heat is the “urban heat island effect” which refers to urban areas being hotter than their non-urban counterparts due to less green cover (e.g. trees) and higher proportions of built, impervious cover. The urban heat island effect is increasing as cooling green infrastructure (e.g. trees, shrubs, irrigated lawns) is increasingly removed and replaced by built infrastructure (e.g. roads, buildings) that absorbs, stores and then radiates heat. 

Edge is Australia’s preeminent provider of thermal mapping, analysis, and management. We use global best practice techniques and approaches, together with leading knowledge and technologies to work with clients to map and quantify hotspots and heat islands, consider social vulnerability, and investigate mitigation and management options, including tree planting priorities and others.
