Urban heat islands


The impact of surface cover and tree canopy on air temperature in Western Sydney

Increasing summer temperatures and urban development in Western Sydney present key challenges for contemporary planning. This research shows that increasing the area of hard surfaces and buildings leads to warming while increasing the area of open spaces and tree canopy leads to cooling.

Benchmarking summer heat across Penrith, New South Wales

This report documents variation of summer temperatures across Penrith, in Western Sydney. Between 14 December 2019 and 31 March 2020, more than 1.4 million measurements of air temperatures were collected using 120 data loggers.
Systematic review

Best practice techniques for urban cooling in Australian climate zones

The main objective of this rapid systematic review is to provide an international literature review of best practice techniques for urban cooling for the major climate zones in Australia.

Beating the heat - cooling canopies for community resilience

Documenting canopy coverage and identifying suitable climate change resilient street tree species, this project will contribute to cooler localised urban environments, increasing community resilience in heat events and raise awareness of climate change resilience within the community.

Canopy tree planting in residential areas

Recommendations within this report aim to implement actions to achieve improvements in the urban climate by improving the canopy cover in the private realm.

The urban heat island in Australian city planning

Extreme heat associated with the Urban Heat Island (UHI) and future climate change will have a disproportional geographic and demographic impact across a city. This research investigates Australian cities' strategic plans for heat reduction to maintain their liveability towards heat stress from the UHI effect.

Understanding land surface temperature differences of local climate zones based on airborne remote sensing data

The local climate zones (LCZ) scheme has attracted the interest of climate researchers as it enables the standardized study of urban heat islands by combining thermal and physical parameters of built and natural structures. Most recent work on LCZ has concentrated on understanding air temperature...

Evaluating the cooling effects of green infrastructure: a systematic review of methods, indicators and data sources

Highlights 165 studies from 2010 to 2017 investigating the cooling effects of green infrastructure were systematically reviewed. Studies were analysed for their spatial patterns, investigation period, typologies studied and methodological aspects. Five major gaps in the literature were identified. Research opportunities for future development were...

A methodological framework to assess the thermal performance of green infrastructure through airborne remote sensing

This paper presents a methodological framework for a more accurate assessment of the thermal performance of green infrastructure (GI) using a combination of airborne remote sensing, field measurements and numerical modelling. The proposed framework consists of: (a) controlling intervening variables and classifying sites according to...

Urban heat island and overheating characteristics in Sydney, Australia. An analysis of multiyear measurements

It has become increasingly important to study the urban heat island phenomenon due to the adverse effects on summertime cooling energy demand, air and water quality and most importantly, heat-related illness and mortality. The present article analyses the magnitude and the characteristics of the urban...
