  • In South Korea, mora than 90% of swine barns had open-style side wall by winch operation, and less than 5% of swine barns were semi-windowless or windowless style. The aisle ventilation system of the barn was changed to roof-wall ventilation system, and the width and the length of barns were 10~12 m and 30~50 m, respectively. The width of aisle satisfying energy save was 2~3 m. The re-modeled barns inhaled air through duct which was opened to aisle and exhaled through forced ventilation fans on the windowless wall which was accomplished by installing planks on the open wall. After remodelling, the culling ratio and energy cost were decreased from 11% (47 heads) to 3% (12 heads) and from 1,550,000 won to 730,000 won, respectively. Hence, re-modeled swine barns raising 400 heads could save 2,835,680 won during winter (from December to March).
