Climate change has been mankind’s main concern over the last century, with its many impacts such as rising temperatures, water stress, increase in natural disasters and reduced thermal comfort in urban spaces due to the Urban Heat Island (UHI) effect, a phenomenon that causes several deaths around the world every year and for which measures must be taken to mitigate its impact. The aim of this paper is to assess the impact of climate change on the urban microclimate and the resulting thermal comfort. The Place de Ettoute in Blida city centre, Algeria, is considered as a case study. This case is considered as a reference on which 3 scenarios, B1, A1B and A2 are applied representing three possible ways of the future of climate change according to the prospective study for 2100 of the IPCC for future periods. Envimet V3.1 is used to model the Ettoute urban square, in a 120x120m square with a 3x3m grid. It is based on a three-dimensional digital model that takes into account fluid dynamics and thermodynamic models to simulate the impact of surfaces, vegetation and the atmosphere at the micro-scale of the square. The comparison between the four scenarios shows an increase in temperature (from 0.5 to 1.24°C), particularly at night (8.8 to 10.03°C), which would reduce thermal comfort in Ettoute square, but scenario B1 has less impact on the urban microclimate and scenario A2 represents the worst case. In addition, a reduction in relative humidity (up to −19%) is expected for the scenarios A1B and A2 while a relative increase would be observed for the B1 scenario up to 2%. This study highlights the urgent need for adequate mitigation measures to reduce the impact of UHI for future periods.
