Résumé

Climate responsive design aims to mitigate extreme heat by consciously integrating climate principles in urban architectures and developments. Thereby, the adoption of climate-responsive design in urban areas is foreseen to increase the adaptation capacities of urban dwellers to overheating. However, behavioural overheating adaptation can also be aspatial (e.g. a change in activity program, clothes, or food regime), and thus not depend on the quality of outdoor spaces. According to the behavioural planned theory, the selection of one of these is determined by the individual knowledge of heat adaptation options, its transaction capacities with its daily routines, and cultural beliefs giving its community belonging. We investigated the nature of the overheating adaptation strategies in the densely-built city-state of Singapore for different extreme thermal perceptions so as to determine whenever and when space matters in individual overheating coping strategies in a tropical climate and mature tertiary society. We used the records of two biometeorological campaigns aiming to assess the thermal sensitivity of acclimatized Singaporeans, which were, on occasion, extended with a survey questionnaire dedicated to overheating behavioural adaptation. Unsurprisingly, extreme sun, rain, and heat triggered adaptative strategies, while extreme humidity and wind did not. Rain adaptation was mainly aspatial, while extreme sun and heat triggered a mix of spatial and aspatial strategies with more option diversity for the sun than for the heat. Some adaptation options were mutualized as for the air conditioning to cope both with extreme heat and humidity sensations. Last, not all the selected adaptation options reflected the national Singaporean programs aiming to promote outdoors: urban parks, seafront or large water reserves although supporting the “city in a garden” marketing were declared to be less used than naturally and artificially covered roads developed close to house units to foster active mobility.
