Experimental investigation on thermal comfort assessment in public open spaces: Case of Jijel, Algeria



This study aims to assess the impact of some paving materials on the outdoor space thermal profile which are of prime importance for their viability and attendance.  This was carried out through a case study in the Mediterranean context of Jijel city. A comparative analysis of thermal indices was done using RayMan model outcome, validated through field measurements and survey. The results highlighted a neutral temperature of 21.2°C and a comfort zone between 18.4°C and 23.9°C obtained via the physiological equivalent temperature index. The results revealed the importance of paving materials albedo on public open spaces thermal profile, and the need for a better knowledge of the thermoradiative properties of materials before their uses.
