With a significant portion of poultry production costs, efficient energy management is imperative for sustainable growth. This study evlauated the influence of regional climate variations and structural configurations of broiler houses on their internal environments and energy demands using previously validated Building Energy Simulation (BES) model.The analysis indicated distinct thermal conditions within broiler houses, primarily driven by regional climate differences and building structures. The model effectively demonstrated the effects of various wall compositions and ventilation systems. The installation of ceiling structures in broiler houses showed a pronounced impact on maintaining appropriate rearing temperatures. Specifically, during winter, the mid-ceiling installations led to a temperature rise of up to 4.5°C, effectively reducing heating loads by 4.7% to 5.7% across various regions. In summer, activating ceiling fans in conjunction with mid-ceiling structures reduced cooling loads by 9.0% to 2.4%. These results underscore the importance of tailored building designs, ventilation systems, and energyefficient practices for broiler houses in diverse climatic conditions. The study suggests that dynamic energy simulations could contribute to the development of more sustainable and climate-adaptive practices in broiler farming.
