The present study was conducted to investigate the effect of electrical and thermal systems optimization on energy consumption in broiler farms. Experiments were conducted in 4 different climates (cold, hot, dry, and temperate) with four treatments (4 broiler farms in each region) and 5 iterations (5 rearing periods per farm) on the Ross 308 strain of broiler chicken in a completely randomized basic design. The results showed that the solutions applied in cold and dry climates had a significant effect on reducing energy consumption (P<0.05). In the hot climate, although the reduction in energy consumption was observed after the application of the solutions, the difference was not statistically significant (P>0.05). Also, the application of solutions in temperate climates created a significant difference in the specific amount of thermal energy consumption per kilo of meat and total energy (P<0.05). Overall, the results of the present experiment showed that optimizing the electrical and thermal systems of broiler houses could reduce energy consumption in all climates.
