I used to try and explain it to them but it's like talking to a brick wall and when I go to the back and see the worn out breaker panel feeding everything I just give up. One time I was recovering refrigerant from a burn out and my recovery unit was bouncing all over the floor. After some investigation I discovered that the outlet the equipment was on and I was using had 240 volts going to a 110 outlet!
I've run into that a couple times where there is 240 on a 110 outlet. Sometimes I get paranoid, and check the outlet with my meter before I plug into it.
Thermal image camera, or even inexpensive temp gun, can be used to cure ignorance.
Probably ain't gonna fix stupid, but you can fix ignorance.
Which makes more sense to you? CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10% ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%
