Abstract

CONTAM is a general purpose, multi-zone (nodal) airflow and contaminant transport analysis tool that can be used to determine inter-zone pressure differences, airflow rates and contaminant transport in complex building structures. This tool was developed by the Building and Fire Research Laboratory of the National Institute of Standards and Technology (NIST) for the analysis of building ventilation systems and has evolved and adapted to accommodate a wide range of building engineering disciplines from indoor air quality analysis to smoke management system design. This report serves two purposes: as a supplement to the CONTAMW 2.0 User Manual with explanations of the most recent enhancements to the program and to document the program. The documentation addresses both the graphical user interface (referred to herein as ContamW) and the numerical solver (referred to herein as ContamX) of version 2.1 of the program, collectively referred to as CONTAM.
