Strong winds can pose a problem, too. I remember fearing that one short co-worker was going to be pulled outside as she tried to close a big casement during a storm. There is a downside to this non-airconditioner business. The Willamette Valley is definitely a temperate climate, but it does get hot in the summer. So we have little air conditioners in the windows in most offices.
Air conditioners take electricity.
So do lots of things that we now use, but that hadn't been thought of when this old building was built. Consequently, sometimes you have to make choices. In the shipping room, for instance, in some years they can't use both the air conditioner and the postage meter at the same time. Several years ago, I worked in a small office that was inadequately wired for the number of people and machines in it. We couldn't have the air conditioner on at the same time as all the typewriters, or we'd blow the circuit breaker.
