Estimates of supply duct leakage were assessed at each collected data point by correcting for changes in the observed supply plenum operating pressure and using a power-law flow-leakage approximation following the procedures in the Duct Blaster manual and ANSI/ASHRAE Standard 152-2004, as shown in Equation 4 (ASHRAE 2004c; The Energy Conservatory 2007).
Airflow and duct leakage tests were conducted using an Energy Conservatory Duct Blaster and Model 3 Blower Door in accordance with ANSI/ASHRAE Standard 152 (ASHRAE 2004c).
