Cold is just inverted hot?

I just had a disturbing discussion with one of Chris’ Nano people that profoundly disturbed me. I was talking with this kid from The South (I assumed this from discussion) and complained about the hotel I stayed in California (or Nevada) last year. The hotel had this sign asking guests to conserve energy. The rooms, on the other hand, were not insulated and the doors had about a centimetre or so of nothing between themselves and doorframes. This caused me to run the air conditioner all night (I can’t sleep with the noise) since the hot air would just seep in. The kid thought I was crazy for wanting to turn the air conditioner off as there is so much energy there is no need to conserve it. She also claimed that insulation would not do anything because the heat gets in anyway. In any case, I am glad to live in the place where building technology is so scientifically advanced, even if the temperature gets down to –40, the furnace only needs to be on for 1/3 of the time.
