It’s worse if you live in a well insulated energy-efficient building. In winter it’s cold so nobody wants to open the windows. The lack of ventilation means that the moisture has nowhere to go and just accumulates.
- morsch 4y agoWe're in central Europe. A few degrees colder than London in Winter, I doubt it matters. I've done it in houses built a hundred years ago (though they were modernized since, obviously) and ones that were build recently with high degrees of insulation (almost but not quite passive). Not an issue. I usually did open the windows for a couple of minutes.
