> It doesn't work that way, exactly because the buildings are well insulated they keep warmth for much longer during summer. Goes both ways, doesn't it? Lots of houses in Sweden have basement/cellar floors as well, and if you have good insulation, you manage to keep more of that below-ground coldness around, compared to if air blew freely through the house. At least that was my experience. > you probably experience it Fortunately not, moved away from my home country in 2012 already :)
