•We present results from a reduced-scale physical model of revolving door.•Air displaced by door rotation is two orders of magnitude inferior to previous data.•Increasing the door rotation speed does not increase significantly the air displaced.•Correlation-based models to be used for on-site estimation of the air displacement.
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.
