We developed inter room fan ventilation system which transports indoor air mutually by small fan installed in the inner wall between rooms, and which is controlled according to the differences of specific enthalpy and CO2 concentration. The object of this study is to verify the improvement of indoor thermal environment by the application of this system. We installed this system into the model house and carried out the field study about temperature, humidity, and energy consumption etc. for nine months in 2005. The results are the following; 1) The ventilation route tend to be formed from LDK toward other rooms although it varied due to the seasons and the use of heating and cooling; 2) It was estimated that this system carried about 1-4 % of heating and cooling energy by transporting air between rooms; 3) We estimated temperature and humidity in non-heated room rose about 2-3°C and 0.6-1.2kg/kgDA by transporting air from heated room in winter.
