Yeah but you use a 60% efficient HRV and you get the benefits of fresh air (I don't think anyone here is going to argue about how important fresh air is) while being able to direct it exactly where you want it to go and remove the stale air from where IAQ is the worst. And to top it off you get a 60% return on your exhaust energy compared to leaks or negative pressure.
Seems like a no brainer to me, but there is the initial investment of $700 or so for the unit and ductwork if you don't already have that stuff.
