Air leakage data from six parallel fan powered terminal units that utilized electronically commutated motors were evaluated to determine if simple models of air leakage could be developed for applications in building energy simulation programs. The data is from an earlier investigation by Edmondson et al (2011). Units with both 8 in. (20.3 cm) and 12 in. (30.5 cm) primary inlets from three manufacturers were evaluated. The analysis included the impact of downstream static pressure, upstream static pressure, and primary airflow on the leakage from the units.
