Abstract. While the livestock industry has been greatly developed recently in Korea, many problems have occurred in terms of maintaining optimum micro-climate in the facility. Especially, many consultants as well as farmers have easily made misunderstanding and wrong judgement on ventilation efficiency and internal airflow distribution. The air flow is the main mechanism of internal environmental distribution such as gas, temperature, humidity, and dusts, but, as well known, the airflow is invisible and difficult to predict and measure. Therefore, it is essential to develop the training materials for the farmers to recognize micro-climate visually. In this study, aerodynamic approach was carried out using CFD (computational fluid dynamics) for combining with VR (virtual reality) technology. First, all research papers, reports, journals, and publications on livestock industry have been reviewed to find representative problems at swine houses during hot and cold seasons in Korea while there are four distinctively different seasons. Then, Open-source CFD, non-commercial software, was used for computing the selected problems and their solutions. The livestock house models were designed based on 2009 Korean Standard of swine houses. These CFD computed results such as airflow, temperature, humidity, gas, etc were applied to VR simulator for educating swine farmers
