Citizens’ preferences of public space elements and supportive features during heat-stress conditions are under particular focus in this paper. Outdoor activity choices in different thermal environments were surveyed in Adelaide from September 2013 to April 2014. This post-activity survey indicates that necessary, optional and social activities decreased during outdoor heat-stress more than any other thermal conditions. %9 Conference paper
