The increasing frequency of severe heat waves poses significant challenges for urban tourism, particularly in Mediterranean cities, where high temperatures can negatively impact the quality of the visitor’s experience. This paper introduces a comprehensive methodological framework designed to assess the effectiveness of heat mitigation efforts in the context of the COOL NOONS project, which aims to test innovative strategies to improve thermal comfort for both urban tourists and residents. The framework utilises a combination of advanced technological tools for gathering data, such as satellite imagery, thermal cameras, GPS tracking, and Wi-Fi-based location tracking. These technologies are anticipated to facilitate meticulous monitoring and analysis of land surface temperatures, microclimatic conditions, and patterns of tourist movement. In addition, the framework includes survey-based methodologies for evaluating visitor satisfaction and adaptive behaviours in response to cooling interventions. The proposed framework provides an effective approach for assessing the effectiveness of urban cooling solutions by incorporating multiple data sources and methods. The insights gained from this framework aim to inform sustainable urban planning and improve the resilience of tourism infrastructure in the face of climate change.
