Water vapour exerts a pressure and areas of high vapour pressure (such as inside our homes) will always seek to equilibrate vapour pressure by moving to areas of lower vapour pressure (outside) and ventilation provides an 'easy' escape for this to happen. However not only does water vapour escape but also heat. The warm moist air is replaced by dryer cooler air which is good but some have suggested this reduces wall surface temperatures leaving them more susceptible to condensation. The cool replacement air also has to be heated to maintain comfort levels within the property and this costs money.

There is no doubt that controlled ventilation will contribute towards the reduction of a condensation problem and create a healthier environment but it probably will not be the complete cure. Other control measures are likely to be necessary and a complete cure lies with the life style activities of the occupants.
