[theophilus88]

I'm working on a 15,000 SF addition for an industrial sized laundry facility and was just curious if anyone know if there are special requirements in the NEC for this sort of facility? Thanks in advance for any info!

Is it public use facility such as a laundromat or is it in house laundering department for say a hospital or industrial facility that does their own laundering on site, or even a company that does commercial laundering for other clients?

Maybe can apply demand factors if you have electric dryers.

GFCI requirements for receptacles at least would apply to any wet locations whether indoor or outdoor or within 6 feet of sinks.

Demand factors might go out the window.
I'd assume it's a damp or possibly wet location, so figure that in.
Probably requires more than the usual amount of ventilation.

It's a massive offsite laundry facility that cleans towels, sheets, and linens for hotels and other businesses.

I bet majority of your machines aren't all that much like a household washer or dryer? Some similar principles maybe but on a larger scale.

Probably VFD driven motors at least on washing machines.

Dryers likely use gas for heat source, probably bigger motors than household dryers, but mostly because they are a bigger units.

Probably not much for wet locations other than any hand washing areas that there may be? (and maybe occasional washer malfunctions which don't exactly count as wet location unless it is something that normally happens.
