Global warming is intensifying the frequency and severity of heat waves, making urban environments increasingly hostile, especially during the summer months. Pavement surfaces are particularly vulnerable, often reaching extreme temperatures that cause significant thermal discomfort, contact burns and material degradation. This study presents an innovative solution based on nature: a cold pavement system that takes advantage of naturally cooled subsurface water to reduce surface temperatures by conduction, without relying on evaporation or water consumption due to the absence of capillarity. The system is particularly suitable for hot climates and outdoor public spaces where users can walk barefoot, such as coastal promenades or water parks. To evaluate its performance, a digital thermal model was developed and experimentally validated in real conditions in Seville, Spain, during the summer of 2023. A sensitivity analysis identified optimal design parameters, including pavement thickness, thermal conductivity, absorptivity and water heat exchange. Results indicate that this passive cooling strategy can reduce surface temperature by up to 20 ◦C compared to conventional pavements, while maintaining safe thermal conditions for more than 80 % of the exposure time and systematically avoiding harmful contact thresholds. This nature-based approach demonstrates great potential to improve outdoor urban thermal comfort, mitigate heat-related health risks, and support the development of more sustainable and climate-resilient urban environments.
