Describes a variation of the conventional tracer gas measurement technique for measuring air change rates. Gives theoretical analysis of measurement results simulated with a computer for a complex system of six rooms where natural ventilation is measured in one case and fan-arrested ventilation in thesecond. Results from computer simulation are a measure of fresh air ventilation and not of a room's total air change rate. Diagrams illustrate assumed distribution under both conditions.
