I am new to the list, forgive me if you have recently covered this.  
Why is there so much focus on exhaust only ventilation.  Although it 
plays an important role in removing moisture from a home it falls short 
of providing reliably good air quality since there is no way to prevent 
air from filtering through the walls, floors and attics.  Whereas 
supply side ventilation gives you the ability to pick your source 
location and to deliver the air to sleeping and living areas.  This 
approach has the added benefit of positively pressurizing the home and 
reducing the likely hood of pulling bad air into the occupied space.
