Do you replace the total air volume in your house three or four times a day? Whoa - sounds wild to me, but air quality wise we should.... If your house has plenty of leaks as older homes do, it probably happens already (and you reheat it all!?) but newer 'air tight' homes need an HRV (heat exchanging ventilation system). Hmmm... Also, indoor humidity levels requirements change with indoor temperature... Keeping the house colder seems to increase condensation. So we should keep a lower relative humidity. Who knew? Everyday Engineering course we're taking is opening up new information to us all....
