%T Limits of thermal adaptation in cities: a case study of Darling Harbour, Sydney %A Ehsan Sharifi %A John Boland %I 50th International Conference of the Architectural Science Association, 7-9 December 2016, Adelaide, Australia %D 2016 %K Open spaces, %K Urban heat islands, %K Thermal environment, %K Thermal adaptation %P 229-238 %U https://apo.org.au/node/233366 %X Climate change projections indicate a likely 3.8°C increase in the average temperature in Australia by 2090. During summer, outdoor heat-stress causes significant thermal discomfort, altering outdoor living preferences. This paper aims to explore the neutral and critical thresholds for outdoor thermal adaptation. The paper reports on outdoor activity change during different outdoor microclimates in Darling harbour, Sydney. Results indicate that outdoor participants adjust their insulation and activity rate by an outdoor neutral thermal threshold of 28-30°C. %9 Conference paper
