AbstractIt is often important to be able to determine the air changes in any occupied space in a building which result from natural or induced air leakage. The direct measurement of this infiltration rate is difficult. The most acceptable method at present involves the use of helium as a tracer gas and measurement of helium concentrations using a katharometer. Some experiments on the techniques and instrumentation are now reported.
