Thermal comfort plays a significant role in encouraging people to utilize outdoor spaces. Therefore, this feature must be analyzed and evaluated in order to be improvised. Computational fluid dynamics (CFD) is an alternative technique that predicts thermal comfort and environmental parameters. Validation of CFD is important to ensure its effectiveness. This study assessed the performance of ENVI-met for its ability to estimate thermal indices (PET) by comparing it to field measurement for various points in a street canyon in Port Said, Egypt, throughout the summer and winter seasons. Except for the limited air velocity correlation, the results presented very good agreement, particularly with respect to the final results of the PET visually curved and numerical values, with an index of agreement value ranging from 0.81 to 0.95. The study's conclusions concern the use of the ENVI-met simulation model as a tool for assessing outdoor thermal comfort. HighlightsOutdoor thermal comfort was investigated in a hot-humid climate.The effectiveness of using a Computational fluid dynamics (CFD) simulation software program such as ENVI-met was evaluated as an alternative technique in urban design.Varied environmental parameters and outdoor thermal comfort indices were evaluated.It was concluded that validating CFD simulation through field measurement was significant in offering integrated decisions for urban design.
