Abstract:
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-flow relationships. This article describes
CONTAMW, a multizone modeling tool.
