Displacement ventilation can create better indoor air quality than conventional mixing ventilation and can also save energy. In cold climates, the heat loss at the perimeter such as windows may cause a cold draught along the wall. This may disturb the displacement ventilation air flow and may cause uncomfortable draught feeling for the people in the room. In this paper, two types of the perimeter system were modeled and simulated by CFD simulation. In Case A, convectors were installed beside the outer wall with single glass. The air exhaust system through double window was mounted on the outer wall in Case B. In addition, the applicability of the air exhaust system through double window was examined under the cooling condition in Case C.
