We try to keep the temperature at least 15C (59F) in the house all night and most of the day during the winters here ... and 21C (70F) during the evenings.
It gets up to 24C (75F) at work, and that is stifling for sitting around in an office.
In the summer we just let the temperature be whatever it will be ... unless it happens to be a rare hot day. Then we'll turn the A/C on for a little while.
And these days I can roast ... absolutely dripping sweat ... at any temperature.
