Participants will learn principles of air leakage and how houses perform as influenced by pressure differences caused by air sealing, placement of mechanical exhaust devices, etc. This training includes classroom, hands on lab work with equipment and field analysis for finding and measuring air leakage using the Blower Door, Blower Door software and interpretation of Blower Door results. This training examines methods for determining cost effective and minimum ventilation requirements. Advanced techniques using pressure gauges to determine potential for back drafting and pressure balancing of duct work on forced air distribution systems are discussed.
