Nowadays, despite complex and sophisticated methods for the energy analysis in buildings, the degree-day method, which is one of the most important energy forecasting techniques, is still important. During the research, heating and cooling degree-day values were calculated using dry-bulb thermometer temperature values of long years of five cities (Diyarbakir, Batman, Siirt, Sirnak and Mardin) located in the Tigris Basin. Six different base temperature values were used for each province located in the research area in order to calculate the heating and cooling degree-day values in broiler breeding. Within the proposed six base temperature values, the most heating degree-day values were in Sirnak, and the least were in Batman province. Cooling degree-day values were calculated in the same way. The most cooling need was in Mardin province, except the base temperature value proposed for the first week. The least cooling day values were in Sirnak province. Regression coefficients were obtained by correlating heating and cooling degree-day values and six proposed base temperature values. It was determined that the regression coefficients for all provinces between cumulative heating and cooling degree-day values (dependent variable) and average annual heating and cooling degree-day values and independent variable, in other words, proposed base temperature values, varied between 0.993-0.999, and there was a very strong relationship in a positive way. If the numbers of heating and cooling degreedays are low in a region, then it can be said that the region is suitable for agricultural production. In accordance with the data obtained in the study area, it was concluded that Batman was the most suitable province for broiler breeding in terms of both heating and cooling degree-days.
