sizing an ERV before blower door test?

BrunoF | Posted in General Questions on

I am aiming for a tight house but I have no way to know how successful my air sealing work is since we are still at rough-in.  If I end up at ACH 3 vs. ACH 1, will that impact how what size ERV I would need?

Also, with an open stair case, will that provide enough air transfer / mixing between 1st and 2nd floor or would folks typically have an ERV for each floor?

Thanks!
