Abstract Cities are particularly sensitive to the effects of climate change, causing an increasing incidence of heat waves. Extreme temperatures can impair the use of public spaces in cities, as heat stress endangers human well-being and health. Identifying suitable adaptation measures to maintain the full functionality of public spaces requires a multidimensional approach, accounting for interrelated scientific, social, and practical aspects. As one result we introduce an inter- and transdisciplinary concept that addresses the challenge of adapting public spaces to climate change. Additionally we present a pilot study from Heidelberg, Germany, where a new, sustainable urban quarter experienced more pronounced heat stress than the historic city centre in the hot and dry summer of 2018. The study shows the suitability of our approach to identify appropriate heat adaptation measures. Solar potential modelling and mental map surveys proved to be particularly effective methods. We find that adaptation measures generate synergy effects by improving both climatic and social conditions.
