7.8.7. Return Leakage Penalty
This is the estimated fraction of energy loss of the return side. The default value is 0.5, which assumes
that of the return air leakage, about half of its energy is lost to outdoors (i.e., the other half of its energy
stays inside the house). This number can be raised if you suspect that there is actually more energy loss
to the outdoors from the return side. For example, if the return goes through a very cold crawl space,
the return leakage would pull in cold air and have a greater effect on the annual HVAC losses.
