A Tool for Modeling Airflow & Contaminant Transport



William S. Dols


Multizone modeling refers to annalysis techniques that use a simplified, zonal representation of a building to study building airflows, pressure differences, and contaminant transport. Each zone is assumed to have uniform temperature, pressure, and contaminant concentrations. Zones typically represent individual rooms but can be entire levels depending on the building layout and the goals of the modeling. Zones are connected through flow paths represented mathematically by pressure-flowrelationships. This article describes CONTAMW [Dols et al. 2000], a multizone modeling tool.
