CONTAM, and other multizone modeling programs, can be useful in a variety of applications to analyze building airflows, pressure differences between zones, and indoor contaminant transport. Its ability to calculate building airflows is useful in assessing building air change rates, interzonal airflow rates, and comparing ventilation strategies including the resultant energy impacts. The analysis of pressure relationships between building zones is particularly useful in analyzing smoke control systems. The contaminant transport simulation capabilities of CONTAM can be useful for performing indoor air quality (IAQ) analysis including IAQ design, contaminant source isolation, IAQ forensics, and exposure analysis.
