Evaluation of heat exhausts impacts on pedestrian thermal comfort

The objective of this research is to study the effect of anthropogenic heat on pedestrian thermal comfort within the urban space. Using infrared camera for different places in El Hussein square to identify the thermal performance under the climatic condition and under the mechanical heat generation sources. Different scenarios in El Hussein Square (Historical Cairo, Egypt) were carried out by simulations and modeling using ENVI-met and ANSYS/CFD to quantitatively assess the microclimatic thermal impacts of those heat exhausts. The results show the effect of heat exhaust in increasing the outdoor air temperature (heat island) as well as affect the outdoor thermal comfort of El Hussein Square due to the reduction of air flow between buildings.
