The National Institute of Standards and Technology (NIST) recently announced that an enhanced version of its CONTAM indoor air quality modeling software is now available. CONTAM is the popular NIST tool that predicts airflows and contaminant concentrations in multizone building systems. CONTAM is based on a graphic interface that allows the user to draw floor plans on a “sketchpad” and employ “icons” to represent airflow paths, ventilation system components, and contaminant sources. CONTAM has been used by NIST and others around the world to study the indoor air quality impacts of heating, ventilation, and air-conditioning systems in single-family residential buildings, ventilation in large mechanically ventilated office buildings, radon entry and transport in large residential, office, and school buildings, and the design and analysis of smoke management systems.
