You are quite right ; to lead in cold air into an insulation to dry out the dead room is the right aproach.
Opposite if warm fume air from the interiours can enter teh dead rooms containing the insulations, the air will get cold and water will condensate, causing a huge energy loss and ruining the insulation and every material that can rot in the room where the air are allowed to condensate water.
Now what you need is maby a ventilation system that act as an aeroplane wing, so the more wind the more ventilation, then please check the vent top I show in this link ;
This vent hat will replace any chimney tops with "smart" idears with a very simple idear ; the more wind the more vaccum will be produced inside the tube, ----- this thing work and will never allow air to enter the opposite way down the tube. Check the design and you will se that a vaccum is created between the two dishes. ------- to produce a constant airflow shuldn't be that big a problem.
