Recently, it has been revising regulation of ventilator installation and detail regulation the secures comfortable & safety indoor air quality(IAQ) and obligated establishment of heat recovery ventilator in new apartment building. In this study, we offers operation and a plan of heat recovery ventilator to energy saving by measure efficiency the come out from outdoor conditions and comparing & analysis the energy saving effect. As a result of in this study was as follows : In case, we think that if it do not show that the upper than average of 30 percents absolute humidity in spring and autumn, it should profitably operation "by-pass mode". (2) Energy saving effect appears the heat recovery ventilator show widely rate ratio compared to constant air volume system.
