A balanced ventilation system employed for continuous ventilation of a residential building is expected to ventilate rooms effectively regardless of condition of outdoor environment and building air-tightness. When local ventilation equipments are used, the balance of supply and exhaust air volume may be lost for air-tight conditions. Experimental survey was performed in this study in a model of apartment house in which a balance ventilation system was installed. The result of this study suggest that lost of balance of supply and exhaust air volume is small in a balanced ventilation system compared with an exhaust-only ventilation system. It was found that increase in the pressure loss on outdoor air duct like a filter especially in supply air significantly reduces net air volume rate of total heat exchanger unit.
