For the purpose of this explanation it is easier to think of the air molecules that were described as footballs in the previous article Condensation 4 above. There are two ways the situation needs to be be approached.

Obviously we are not able to stop breathing or perspiring but we should consider all other water vapour generating activities that take place in our homes such as cooking, bathing, clothes drying etc. Large dogs and tropical fish tanks also contribute significant levels of water vapour into the atmosphere. Whenever possible the water vapour unavoidably generated by each of these activities should be forcibly extracted at source directly to the outside. By doing this the amount of water vapour suspended in the atmosphere within a property is reduced thus there is less water vapour in the atmosphere to potentially be deposited as condensation. Therefore even if the air is cooled it may still be able to support the reduced amount of water vapour. If forced extraction is not possible a correctly used good domestic dehumidifier (possibly more than one) will considerably reduce the amount of water vapour  suspended in the atmosphere within a property. So if for example you dry clothes inside on radiators etc. stop doing this immediately - the result will be dramatic.

The second approach to be used in conjunction with the above is to provide constant adequate dry heat combined with good levels of insulation. Not only will a constant supply of heat increase the temperature of wall surfaces meaning the likelihood of condensation forming is reduced, but it will also increase the ability of the atmosphere to support water vapour. If wall surfaces are kept warmer by insulation then they are more likely to be above dew point temperature and the water vapour will remain suspended in the atmosphere and not be deposited as condensation.
