As climate change intensifies the frequency and severity of urban heatwaves, elderly populations are becoming increasingly vulnerable to outdoor thermal stress, particularly in dense Mediterranean cities. This study addresses critical need for micro-scale, climate-responsive design strategies that enhance comfort aging residents historically underserved neighborhoods. Focusing on refugee-built area Nikea Greater Athens, this research explores effectiveness nature-based solutions (NBS) mitigating extreme heat through spatial interventions tailored needs older adults. Using ENVI-met 5.6.1, two scenarios were simulated: a baseline scenario reflecting existing conditions an optimal incorporating mature tree planting water features. The results analyzed across three key time points—morning, peak afternoon, evening—to capture diurnal variations. findings demonstrate NBS significantly reduce Physiological Equivalent Temperature (PET), with improvements exceeding 14 °C shaded zones. highlights value fine-grained, promoting equity supporting adaptation populations.

Urban heat islands (UHIs) are a phenomenon of temperature rising within urban areas relative to their rural counterparts. UHIs becoming an increasingly common problem in large cities, which appear due excessive urbanization and reductions natural cover vegetation. This negatively affects the quality life residents affected city, causing discomfort, reducing air quality, increasing energy demand. In this study, were detected analyzed city Split, Croatia, using data from Landsat 8 9 satellite missions ground-based measurements land surface temperatures, conducted July, August, September 2024. research compares sensor-based analysis results proposal new index: Combined Thermal Index. The main feature index, combines measured perceived temperature, is improve understanding impact (Split), compared existing indices. So far, LST have not been combined, nor they combined with human perception important case because it these people who will ultimately feel rise temperature.

Urban heat island (UHI) effects are increasingly recognised as a significant challenge arising from urbanisation, leading to elevated temperatures within urban areas that pose risks public health and undermine the sustainability of cities. Effective UHI management requires high-resolution timely mapping temperature patterns guide interventions. Traditional methods for often lack spatial accuracy efficiency necessary detailed analysis, especially in complex environments. This study integrates artificial intelligence (Urban AI) by presenting U-Net model tailored metropolitan area Adelaide, South Australia. Trained on thermal data Australian Government Data Directory, captures pixel-level variations across diverse landscapes, including densely built areas, suburban zones, green spaces. Achieving low Mean Squared Error (MSE) 0.0029 processing each map less than 30 seconds, demonstrates exceptional computational efficiency. The model, an AI agent, offers scalable tool supporting real-time assessments facilitating targeted mitigation efforts. By bridging gap between advanced geospatial modelling practical planning, it enables data-driven decisions enhance climate resilience, optimise infrastructure, improve rapidly urbanising regions. approach highlights transformative potential addressing challenges, delivering precise actionable insights support sustainable climate-adaptive
