    There is an idea that the moisture inside a building needs to be “in balance” what does this mean and is this idea a useful one?

    Sounds like;
    New Age Nonsense
    Eco Nonsense
    Marketing Nonsense

    But as long as it has vibration fields and resonance, it will be fine, I am sure:

    Once again, if you gave us half a clue what you're talking about, we'd be better placed to consider an answer.

    A reasonable video - better that it exists than it doesn't. I don't have any problem at all with the notion of balance they present. I would have preferred it if they didn't introduce the nonsense of air 'holding' moisture. They mentioned a link to further information, but I didn't see one, so that's a bit useless.

    The problem I have with balance is that in all homes water and moisture are in equilibrium, problems happen when temperatures change, cold surfaces are present when there is high humidity, moisture is added etc.

    It makes it sound like if the house is in balance then there won’t be problems whereas in reality as soon as moisture is added and/or trmperatures change or moisture added there will be problems.

    Posted By: tonyThe problem I have with balance is that in all homes water and moisture are in equilibrium,

    Well that isn't true for starters. For example if it is in equilibrium and then I warm the house, it is no longer in equilibrium until some more water vapour has evaporated or infiltrated. Or if I cool it, then water may start condensing.

    problems happen when temperatures change, cold surfaces are present when there is high humidity, moisture is added etc.

    Exactly. Problems occur when water and vapour are not in equilibrium (or balance). They specifically mention cold surfaces as a possible cause of problems, I think.

    It makes it sound like if the house is in balance then there won’t be problems whereas in reality as soon as moisture is added and/or trmperatures change or moisture added there will be problems.

    If moisture is added or temperature is changed then the RH changes and when it is outside their 'balance' range of 40% to 65% there's a risk of problems developing. Within that range, it's pretty safe to say that there won't be moisture problems.
