This paper presents an experimental study on a reduced scale model to quantify the air displacement due to the revolution of revolving doors. The results show that the air displaced by revolving doors increases only slightly with the rotation speed, and is about two orders of magnitude less than values currently used in the calculation of air infiltration rate, for the same conditions. The correlation-based models developed in this study from experimental data are proposed to be used for the estimation of the air infiltration rates of existing revolving doors that are installed in large commercial or institutional buildings.
