Nipsmum I’m in NE Scotland, too, and agree that overheating isn’t often a problem here! I do have one fan, though, as our sitting room gets very hot as it faces directly south. It can get too hot even in winter on a sunny day.
For those of you who are suffering with heat, a tip to use if you run a fan is to place a bowl of ice directly in front of the fan so the air blows over it. Or hang a damp sheet over an airer and let the fan blow through that. The evaporation helps reduce the room temperature.
It’s interesting to look at old buildings in the tropics, as they were built to account for the climate. The roofs have overhangs to prevent direct sun shining in. Rooms have high ceilings and there are gaps above each door and in the outside walls which draw the hot air and funnel it outside. When we lived in Indonesia I was fascinated to learn that on Bali it’s perfectly possibly to live without AC by careful positioning of buildings to catch breezes and utilising building methods as mentioned above.
Of course, they don’t have to later cope with freezing winters!
