Part 1 Dilution Ventilation and IAQ

In this video, David Dougan discusses the steps to achieve acceptable IAQ requires understanding the contaminants of concern and methods to maintain contaminants below threshold levels, applicable industry standards, codes, and rating systems. Contaminant level maintenance and acceptable IAQ using outdoor air for contaminant dilution and filtration for contaminant removal are the primary means to achieve proper IAQ. We will review outdoor airflow intake rate factors and the control to achieve acceptable IAQ.
