In this study, the indoor supplied temperature according to variation of outdoor temperature in cooling and heating seasons was drawn when the heat recovery system and the floor embedded ventilation system were applied. Besides, the heat loss due to ventilation was analyzed by using the drawn results. The results of the study can be summarized as follows. 1) The indoor supplied temperature of the heat recovery ventilation system was averagely to be 25.91℃ during the cooling season and 17.50℃ for a during the heating season. It showed the supplied temperature above zero even under the lowest outdoor temperature of -15℃. 2) The indoor supplied temperature of the floor embedded ventilation system was averagely to be 25.08℃ during the cooling season and 22.04℃ for a during the heating season. 3) The heat loss of the heat recovery ventilation system was found to be -16.29~-35.69Wh in case of a cooling season and 53.19~117.83Wh in case of a heating season. It was found that it could save the energy of 74.27% on average compared to the Type 1 ventilation system. 4) The heat loss of the floor embedded ventilation system were calculated, it was found to be -46.33~-126.38Wh for a cooling season and 235.35~520.38Wh for a heating season, which similar to the Type 1 ventilation system. 5) Compared the heat loss of the heat recovery ventilation system with that of the floor embedded ventilation system, it was found that the heat recovery ventilation system could save the energy of 74.87% on average compared to the floor embedded ventilation system. As a result of the study, it was shown that the application of the heat recovery ventilation system is appropriate in order to minimize the loss of energy for cooling and heating according to the application of a ventilation system.
