The purpose of this study is to estimate the accuracy of the Supply Rate Fulfilment (SRF)value measured by using tracer gas on a test house. The SRF is intended to evaluate quantityindex and is defined as the ratio of the effective supply rate to the substantial required freshair supply rate. The procedures to measure the SRF value with use of tracer gas techniques,which are constant concentration method and constant injection method, were shown. TheSRF values of the each room in the test house were measured. These measured SRF valueswere compared to the theological values, which were calculated by the ?P method and theairflow network model. The following are experimental results on the test house:1. Whether or not the SRF values are fulfilled the SRF values itself were calculated.2. The measured mean SRF values accorded with theological values.3. The SRF value measured by tracer gas is useful in terms of practical standpoint.
