Reference Guide states under Data Center heading: IT energy consumption, as measured from an uninterruptible power supply (UPS) output meter, should be metered separately from non-IT equipment, such as HVAC, plug loads, and lighting. If the UPS system supports non-IT loads that amount to more than 10% of its load, such as lighting or cooling, this non-IT load should also be submetered.
Questions:
1. For a Non-Data Center building, is total building space cooling end use the sum of IT Room space cooling and Non-IT Room space cooling (remaining building spaces) or is IT Room space cooling considered a separate end use?
2. If IT Room space cooling is a separate end use, then energy model should reflect as individual end use, correct?

1. It is your choice. If it is a substantial load I would model it as a separate end use. Many office building have a data room or closet and we would typically include that with the other loads. If the IT load is greater than typical I would want to break it out.
2. yes

Hi Mark,
1. Yes, and usually cooling space end use is even broken down further into water side and air side.
2. Yes.

Afogreen Build,
Is it REQUIRED for cooling space end use to be broken down further into water-side and air-side?
Thank you.

If the IT cooling load is greater than 10% then yes it is required.
