If you want to find good candidates for saving the campus tons of money, go to the roof of one of the tallest buildings on a cold day and look for the buildings that are venting lots of steam. They likely have a failed steam trap somewhere in the building. It's not uncommon for failed steam traps to save thousands of dollars a year apiece when fixed.
