The phenomenon of climate change is one of the biggest challenges for the world in the coming
years. This phenomenon will affect many cities in Egypt such as Aswan city. The poor thermal
performance and the thermal discomfort in urban spaces of Aswan city during the summer period
are considered as the main problem of this paper. This problem may be more complicated in the
future due to the phenomenon of climate change and its various effects such as increasing of
temperature in urban spaces. So this paper aims to evaluate the thermal performance of one of those
urban spaces as a first step towards achieving the best condition of thermal comfort in these urban
spaces by 2020. This goal will not be achieved without improving the thermal performance of these
urban spaces through using various climate control strategies. Also it will not be achieved without
redirecting urban designers towards the study of the phenomenon of climate change and its potential
impact and put them into consideration when designing their urban spaces. Simulation programs
were used to achieve this goal. Also analytical method was used for the analysis of the results that
are obtained through simulation software “Autodesk Simulation CFD 2013", Thermal Comfort
Index Calculator and “Ccworldweathergen" program.
