[Bldg-sim] Precision Coolers in Server Rooms?

[David S Eldridge]

25% is the suggested minimum process energy use - the actual process use should be modeled, even if greater than 25%.

Hi Omer

Precision coolers/ACs in server rooms should not be counted under process energy but if your baseline case HVAC system type is 5, 6, 7 or 8 (Table G 3.1.1A) you can model a separate HVAC system type for server rooms as per exceptions to G3.1.1. This could be either system 3 or 4.

Dear All,

Would you consider precision coolers in server rooms to be process energy?
This is how I would like to apply in my model for LEED EAc1 (essentially
not modelling any precision coolers and dumping it away under the default
25% value for process energy). Any opinions?

Thank you,

Omer Moltay, LEED AP
