[Equest-users] Baseline Exhaust Air Energy Recovery Requirement

[David Reddy]

This brings up another interesting question.  If heat recovery does not 
operate in one of the modes of the baseline design simulation, is it 
assumed that you _do not_ get the additional fan power credit for that 
particular mode (i.e. baseline has a bypass around the ERV if there is 
no energy recovery occurring).
