Abstract: The current study dealt with the calculation and modeling of cooling degree-hours for some Iraqi cities, represented by Mosul city as a model for the Northern cities, Baghdad as a model for the central cities and Basra as a model for the Southern cities. This research was based on previous actual dry-bulb temperature data recorded over the previous 10 years. These data were used to calculate the actual values of the cooling degree-hours for different base temperatures ranging from 14-28°C to cover all cooling application requirement data. In turn, these data were used to obtain the appropriate mathematical model which can be used to calculate cooling degree-hours values from any base temperature with a small error rate ranging from 0-4% over the Summer months for all locations. And after the success of the developed model in three studied cities which represented three different climatic pattern regions in Iraq, developed model can be used as a general model to predicate the cooling degree-hours for any location in Iraq at any base temperature after knowing the mean value and the standard deviation of the dry-bulb temperature for the concerned location.
