I remember an interesting call I got back when I lived in Texas. I was on a troubleshooting call to a church in Southlake, Tx. They were having issues cooling down the rooms in the children's wing and they couldn't seem to figure out why. Upon checking the air handlers sure enough the discharge air set-point wasn't being met despite the cooling valve being 100% open.

While you are reading this article a good percentage of you are sucking hot humid air into your building just to cool it down.

Sucks doesn't it? You spend all this money to control your building only to have your energy budget being blown by some hot humid air.

Its right there in front of you. Can you see it?
