New grow room HVAC?

Designing a new grow room for 2000 sq ft of canopy and 125 1k HPS bulbs.

It will most likely be divided into 4 or 5 rooms. I'm thinking 2 x 500 sq. ft., 1x 600 sq ft. and the 400 will be divided into 2 rooms so I can do comparison grows, different lights, nutrients, etc. or clone rooms.

The MAN wants me to put in a 60,000 gal. water tank for fire suppression.

Can I use the tank, above ground as of now, to cool the water of a chiller system of the size needed to cool my grow.

I am located where it gets to the 80's in summer and freezes a little bit in the winter.

So?

Pretty sure ICC prevents any alternate uses of the fire prevention / supression gear.

Also on a system that large you should really be trying to get every ounce of electrical efficiency and HVAC redundancy out of it. Mini split systems are much more efficient than traditional A/C's or chillers. Also its super easy to throw an extra air conditioner in each room. You have to keep in mind its not if your equipment will fail, its when it will fail, that way when one does kick the bucket you dont have to pay emergency fee's to your contractors or shut your rooms down or burn a harvest just because of one unit.

I think Snaps is one of the only other people on here who has experience building commercial ops and I'm sure he will agree.

with 150 K of hps lights I think a water cooled geothermal system may be cheaper. If I can use the fire tank as my cooling reservoir and not run a 1/2 mile of pipe underground it may be cheaper in the long run.

Don't know just asking if it would work.

you'll save money in the long run. a lot of it too.

60,000 gallons? What county is requiring this? What's the reasoning?

Skagit. reportedly to make up for inadequate fire flow.

That or put in a new water line. The size of the tank may be negotiable. 2 500 gal fire streams would last for 60 min. with that much water. Seems like a lot. Don't know if they could staff 2 500 gal/ min. streams....

Maybe I will offer to sprinkler the building. That only costs about $8K
