Where does heat get rejected to if this is the case?

That I don't know as I'm not a HVAC expert. All I can tell you is from my observations from working in and discussions of the suspended ceiling, having been in that area and the roof multiple times. Have you been in that suspended ceiling before?

The actual design of the suspended ceiling is an outdated bad design. If you've ever been up there, you'd understand..........
This reminds me. It isn't now like it was originally designed. There was no provision for rigging from the ceiling beams as the wood ceiling totally covered the underside of the beams in a solid wood ceiling. Gaps were cut away over time to allow things to be rigged and eventually they made pretty much every beam that could potentially be a rigging point accessible. So when the ceiling was solid except for a few lighting bays there is a possibility that much less heat could make its way to this ceiling area so provisions for freezing of the fire suppression system could have been a possibility.

I was in band and choir in high school (NERD) and it is so painful. I don't know what's worse, clapping in rhythm to the intro song or how fast fans start clapping during the fight song
Lew will tell you that there are times when I just have to stop...because it's so annoying to have everyone around me out of sync. It can almost make you nauseous!

OK, I misunderstood what you were referring to in your original message. CF's resident Plumber's Helper was talking about why water would be at the top, you mentioned outdated design, hence my confusion.

And no, I've never been up there. No desire to go there either.

It'd be interesting to see the energy use of HIlton. I'm betting it's in cooling most of the year. I tried the FPM site, but since I'm not on an ISU network or VPN, it wouldn't show it to me.

I gotchya!

From my guess, they use chilled water to cool and condition the air.

Has anyone ever seen this old design concept of Hilton?

When there's a crowd, sure. But I'm sure it is in heating most of the winter. And when it's in cooling in the winter, it would most likely be economizer cooling.
There'd be plenty of "regular" spaces in Hilton that would behave in heating/cooling more like a typical building and less like an arena - offices, locker rooms, etc.

True, but those spaces are relatively small in comparison to the overall building.

As far as economizer goes, you're probably right. I was forced into HVAC in the South, so there's not too much of that down here as compared to Iowa.

Did the fire alarm sound or trigger silent? A large enough leak would have tripped flow switch(es) tied to the alarm and send facilities folk scurrying to Hilton to close isolation valves of that branch, perhaps sending a fire department.

A chilled water leak of size would have shown up as loss of pressure. Again sending facilities folks.

While sprinkler water reeks to high heaven, chemically treated chilled water can reek too. Although ISU is eco conscious probable using low odor, bio friendly products.

I’m sure ISU has extensive piping documentation, finding the person, knowing the location of the valve can be time consuming.

My seat is in 213.....hoping for dry, odor free seat.
