In an IT room there are envelope loads and equipment loads due to HVAC needed to cool the space. Also the electric load due to the IT equipment running. It is clear to me that this last one is a process load (it is similar to a plug load), what it is not clear is if the HVAC load to cool the space is non process or process since you have the envelope and the IT equipment load. Can I separate those two loads and treat them separately?

Sounds like non process to me. This is a bit of a grey area and can be difficult to draw a line. For an IT room it seems like it would be more throuble than it may be worth. Any reason you may want to model it as process? Claiming savings? Under 25%?

Don't get me wrong, I would love to model it as a non-process load, I just thought it was a process load. Electrical consumption of the IT equipment is also a non process load??? What is the reasoning behind process and non process loads? If equipment and computers are process load why IT equipment shouldn't? I guess the reasoning would be that the IT equipment is used to maintain amenities for the occupants.
Thanks in advance for the clarification
Best.

No the IT equipment itself is definately a process load.
The terms process load and nonregulated loads are used interchangably. Anything not regulated by 90.1 is considered a process load. This is why the space conditioning in an IT room is a bit gray. 90.1 clearly regulates the cooling of interior spaces but typically for the comfort of people, not machines.

Ok. It's clear now.
Thanks.
