This paper discusses three methods for measuring inter-zonal air movements in two-zone buildings: initial injection of one tracer into a single room, repeated injection of one tracer into two rooms, and initial injection of two tracers into two rooms. The description of these methods includes an outline of the theoretical background, the presentation of suitable injection strategies and algorithms for the evaluation of the concentration profiles. A detailed error analysis using Monte-Carlo-simulation shows the precision of these methods for a variety of cases, such as different magnitudes of the inter-zonal airflows and various measurement durations.
