This paper presents results of measurements of VOCs and aldehydes released from partition panel used in office. The emission rate of VOCs and aldehydes from panel is measured using a full-scale stainless test chamber (19.7m^3). Temperature and air humidity in the test chamber are controlled to 28±0.5℃ and 50±5%. The air change rate is 0.5h^<-1>. The coefficient of air change performance and convection mass transfer coefficient over the material surface are computed by CFD. It is demonstrated that the convection resistance over the material surface affects the emission rates of VOCs and aldehydes from the partition panel by test chamber experiment and CFD.
