This study carries out a field measurement survey and CFD calculation about the heat loss of a house when heated by the floor heating and the air conditioning were analyzed in detail. The energy consumption in the actual condition of both the floor heating and the air conditioning is clarified. The results of the measurement are as follows: (1) In this investigation, the heat load of the floor heating is 421[MJ/day}, the heat load of the air-conditioning is 405[MJ/day]. (2) CFD calculation results that SET is about 22[℃], heat loss of a floor heating is more than air-conditioning. (3) Wall surface temperature of the floor heating becomes relatively high, the heat losses from a wall become large. (4) Room air temperature of floor heating is lower than air-conditioning, the heat load of ventilation is smaller than floor heating.
