My situation:

- 3200 sq ft fitness center open 24/7
- Cost of running everything but lights and AC is minimal
- ~30 foot ceilings(!) making for huge ft^3
- In NC so it get HOT during summer
- Lights that stay on 24/7 are all fluorescent (I think)
- I put the AC on 72 during day and 75 at night. Any hotter and I think customers would complain.
- The duct work for the AC is exposed (huge pipes from 2 units) and blows down from vents about 15′ in the air.

My power bills over the last 3 months have been $720,$750,$850 — there has to be a way to reduce it!

So far, we’ve added shades to the windows and had the AC tested to make sure it was running ok

Other things I’ve considered
1) lowering all the duct work by about 5 feet so the cool air (hot air in winter) gets to patrons quicker and goes through less hot air
2) Putting lights on dimmer (although I think the culprit is AC)
3) Adding ceiling fans to pull hot air/push cold air (depending on where they are placed)

Please help!!
