IS-2005-43: A Study of Demand-Controlled Ventilation and Constant Air Volume Systems

This paper, by Mohsen Soleimani-Mohseni and Bertil Thomas, deals with the study of the demand-controlled ventilation systems and the need for a constant volume of replacement air when purging in-building pollutants. The study shows that demand-controlled ventilation, using a feedback system, requires less integrated outdoor air flow in order to maintain an accepted air quality.
