Description: As meat consumption increases, the proportion of livestock industry to total agricultural production is increasing every year. Broiler production accounted for 11.5% of the livestock production in 2018. However, the breeding environment of broiler is gradually deteriorating due to heatwaves caused by recent global warming and high density of breeding. Also, broilers have difficulty regulating their body temperature, as they have high metabolic heat generation and few sweat glands. Thus, broilers are vulnerable to high summer temperatures. And tunnel ventilation is a typical method used in domestic broiler houses to effectively relieve heat stress in summer. The tunnel can directly transmit high wind speed to the broilers inside the house too. However, heat stress was not evaluated under various broiler growth conditions and livestock ventilation conditions. The purpose of this study is to validate and develop an energy model to quantitatively evaluate the heat stress of livestock using building energy simulation. In a mechanically ventilated broiler house, external weather and internal microclimate data were measured at various points, and model validation was performed using this data. The conditions for the simulation included the livestock age, breeding density, the thermal insulation of the wall, ventilation of the livestock, and the presence of a cooling pad. The results of the heat stress evaluation were derived and analyzed through the temperature-humidity index. As a result, it was possible to reduce the damage to livestock because of climate change, by preventing mortality due to the heat stress of the broilers inside the house.
