The purpose of this paper is to evaluate the performance of four kinds of ventilation systems from the point of view of air exchange, indoor air pollution, and space heating load under Japanese conditions by numerical simulation. TVOC and CO2 are selected to characterise the indoor air quality impact to residents. The results show that the equivalent leakage area has great influence on air movement. In addition, compared with other kinds of ventilation systems, mechanical central supply and exhaust ventilation system shows its advantages for minimising energy consumption and maintaining an acceptable indoor air quality.
