Perhaps “cool” is the wrong word. Did you notice the temperature recorded inside the house? 24degC (26 in the office). A little too warm for my taste.
Unless it was taken in the summer, in which case it's really cold.
Am I wooshing a joke? That's 75F which is hardly cold in any season.
For summer that's right about the upper end of tolerable range if I don't want to hear the A/C starting/stopping just for a few degrees of cooling.
That's about perfect for my office, keeps my hands limber and avoids carpal tunnel, but not warm enough to sweat. I do like it more like 19C at night for sleeping, though.
