The Donga has an article describing how Korea and Japan have policies for temperature regulation in government offices including a set-point for air conditioners, a not-that-cool 28 degrees. This is another article relating energy saving measures to the high price of fuel.
The point is a good one, but Korea could make maintain cool rooms (and warm ones in the winter) while making great energy savings with a ridiculously simple procedure: close the freakin' doors and windows! My head spins when I see an active air conditioner next to an open window or cold classrooms in the winter with every exterior door wide open.
I do think using air conditioners to moderately cool and dry the air is a good idea, too.
