There were many Issues In the existing ventilation rate measuring methods such as the spatial distribution of tracer gas, the environmental effect of the tracer gas itself such as it being a greenhouse gas and etc. A new method for ventilation measurement using an Open Path Fourier Transform Infrared Spectroscopy (OP-FTIR) will be proposed. The tracer gas between the optical-path will be measured so the effect of spatial distribution of the tracer gas will be moderated. A feasibility study this measuring method was taken place using an OP-FTIR and compared with the traditional measurement method using a Photoacoustic Gas Monitor. As a result the errors between these 2 methods were about 10%. Considering the artificial errors, analytical errors and other errors, we can say that this measuring method is feasible for practice.
