Examines various definitions of ventilation efficiency. When using tracer gas techniques the definition of a ventilation system's efficiency can be based on the slope of the tracer gas curve, or the ratio between concentrations, or the area under the curve. Examines the consequences of these definitions for a simple theoretical model. Presents experimental measurements on a test room which show that sometimes very low ventilation efficiency can occur.
