Full Description

This paper presents detailed experimental results for the transient dispersion of a tracer gas following internal releases in a building. Ambient air analyzers were used to simultaneously measure the real-time concentrations of tracer gas at eight locations in the building following single-point releases. The building and its systems were operated in selected known states before, during, and after the tracer gas releases. Results are presented to illustrate the dispersion of sulfur hexafluoride (SF₆) for three different release/building operation scenarios. The results of the experiments from this case study provide valuable insight relevant to the proper planning, design, construction, and operation of buildings.
