For my area at work, the air conditioning register is in my office, so I turned it off. Still, with other departments setting theirs on "Antarctica", the temps in my area manage to remain at 20 degrees celsius throughout the day. Some of my colleagues (mostly foreigners) use space heaters. Even though it's only in the sixties and seventies outdoors, all the stores already have the air conditioning on, so do most of my neighbors. A few years ago, I remember consulting airline documentation for a trial, and it stated something to the effect that "Americans being bulkier, they need temperatures to remain lower in the airplane." As the summer nears, can someone provide the outline of an answer as to why it has to be so f... freezing indoors? The waste of energy is mind-boggling to me.
