This one almost goes without saying. I'm in my office with heat blasting on me so I check the gauge to turn down the temperature.
Yes, it is only 1ºC outside, so we need heat. But if it were friggin' 30ºC outside right now, you'd be blasting the A/C!!!! Why do the people at Bugil, students included, believe that turning up the heat to 30ºC will make the room heat up faster? Put a sweater on people!
