You might find the passivehause projects in Europe worth looking into. They have taken it to the extreme and are hitting the limits of needed ventilation. But you can steal heat out of stale air being vented and transfer it to fresh cold air being drawn in. Also you can supply fresh cold air to the stove or stoves and not have them sucking and eight inch pipe worth under the doors etc.

Note: I have no interest with them, they are just something to consider with a grain of salt.
I have an heat/cool tranfer type ventilation system as my house was sprayed with icynene (sp?) foam insulation requiring introduction of outside air. The marginally work and I have installed a timer on it to cut down on energy loss. Just have to be careful about eating bean soup.
