Working spaces in modem buildings are easily formed by interior partitions because these buildings have been designed and constructed as open spaces for flexibility. This could lead to an indoor environment which might be different from the intended design. In this study, the effect of partition on the indoor air quality in a model room has been investigated with different configurations such as the height of' partition and the gap between partition and floor. A small-scale model room with a data acquisition system has been used to monitor the tracer gas concentration with different test conditions in mixing ventilation. In addition, CFD simulations, using Vortex-2, have been carried out for the same conditions as for the model experiments. It is found that the height of partition influences the ventilation effectiveness in the model room. However the gap under the partition has more significant effect than the partition height.
