Responding to the urban heat island: Optimising the implementation of green infrastructure
Researchers: A/Prof Nick Williams, Dr Andy Coutts (Monash University), A/Prof Steve Livesley, Dr Briony Norton
Funding: Victorian Centre for Climate Change Adaptation (2011-2013)
In this project, we assessed the effectiveness of different green infrastructure systems for urban cooling and developed a systematic approach for urban land managers to optimise the selection and implementation of green infrastructure options.
- quantified the range in land surface temperatures and near-surface air temperatures for different urban surface types and vegetation types using DPCD/DSE collected data
- identified surface types and features that tend to create localised heat exposure or cooling
- assessed the thermal performance of different types green infrastructure for encouraging urban cooling (e.g. a green roof, green wall, and street trees) by monitoring green infrastructure surface temperatures
- identified and assessed key considerations for integration of green infrastructure into existing urban areas including available space, existing infrastructure, installation and maintenance costs
- analysed the institutional opportunities and barriers to implementation
- developed a systematic approach for selecting and implementing green infrastructure that considers the more vulnerable sections of society, heat exposure ‘hot spots’ and the local context
- translated the scientific findings into user-friendly guidance material for use by policy-makers and practitioners.
