Abstract :
[en] The comfort sensation of pedestrians outdoors greatly impacts residents' happiness and standard of living. With the Earth's temperature expected to rise due to global warming, people's outdoor activities will be limited. Therefore, it's essential to intensify the evaluation of the effects of heat reduction strategies on outdoor thermal comfort in cities to enhance human well-being. At the same time, safeguarding historical and cultural heritage as required by Sustainable Development Goal 11. Across the literature, a limited number of studies have investigated the implementation of nature-based solutions as heat mitigation strategies in historical cities. This research investigates the influence of combining different nature-based solutions and scenarios. Combining NBS involves modifying the urban morphology, street and facade surfaces, and vegetation intensity to examine the cooling impact and enhancement of thermal comfort. The research methodology involves conducting in situ measurements in a traditional urban fabric in Algiers's old city fabric, which is classified as a world heritage site. The research assesses the climatic conditions during a typical summer heat wave using the Physiological Equivalent Temperature (PET). Then, numerical simulations are performed using CFD software Envi-met for different scenarios. The results highlight that combining mitigation strategies shows limited improvement, with the outcome primarily influenced by one or two parameters. Also, In some instances, the use of nature-based solutions to reduce the heat has a slightly better cooling effect (ΔPET = 16.8 °C) compared to morphological reconstruction (ΔPET = 15.2 °C), yielding a difference of 1.6 °C in PET values. The reported results offer practical guidance for stakeholders who renovate traditional cities in Mediterranean climates to make informed decisions about urban heat mitigation methods. This research presents innovative perspectives by analyzing nature-based solutions at two different levels. First, individually, to gauge their impact and by combining strategies of the same category. Then by combining the most favorable scenarios for an in-depth examination. The research also balances the reduction of urban heat with the preservation of cultural heritage.
