The paper examines the impact of climate change on the cooling and heating load of a sample building in 1000 locations across Iran. Although climate change affects the behavior of residents, building layers, tariffs of energy carriers, and other goods in addition to changing weather conditions, in this study only the effects of changing weather conditions on cooling and heating load have been studied. The results can be utilized to obtain a fair price for energy carriers in different climates, plan energy carriers' supply chains, and check the appropriate technologies to reduce energy consumption (insulations, water heaters, and other similar cases). In order to quantify the impact of climate changes on cooling and heating load, engineering software has been used. Investigating the cooling load and heating calculated shows that the range of the heating load is far greater than the range of the cooling load, and in general, the average cooling load is higher than the heating load. The maximum, average and minimum heating load was 198 , 7.2 , and close to zero, respectively. Moreover, the maximum, average and minimum cooling load was 166 , 67 , and 3.6 , respectively.
