I audited a commercial building which, on the beautiful October day, was 
running their air conditioners on a very short cycle.  I stood and 
listened to them for 10 minutes, and they went on for 30 seconds, off 
for 90.  Turns out the sophisticated control systems were set to 72°F 
for both heating and cooling, and they were fighting it out all day 
long.  Mind you it was about 72°F *outside*!

We got a nice thank you note from them that Christmas, saying that they 
had saved over $4,000 already by implementing our recommendations.


Thank You Kindly,

Corwyn
