I should have given more info in the first place.
My BH is a stand alone 3 storey building and have 177 4" VH. Only 10% were closed prior to opening all. Now I shall do an experiment to close all VH floor by floor and monitor the reading of hygrometer.
I have this logic in mind but not sure whether it is correct or not. Damper and cooler air is heavier, therefore the ground floor should have more air pressure then the upper floors, thus open up VH in ground floor will allow damp air to flow out ?
I thought hot air has more energy and therefore more pressure. I agreed what WW said. Try to close all the VH first. After all your BH is new BH, close all VH can help to keep the aroma smell in your BH.My BH is a stand alone 3 storey building and have 177 4" VH. Only 10% were closed prior to opening all.
