@Satsuma @Lady Definitely, though now that I'm working from home I'm not sure it's *more* efficient to be air conditioning a bunch of homes to a similar level. (Of course, many homes - and offices, for that matter - will be air conditioned even with nobody in them, so the tradeoffs aren't exact.)
@Lady Yeah, I've definitely noticed this as well. (Though of course adequate air conditioning can mitigate it, but it still takes time to cool off if you've been warm.)
