NC-2009 EAp2:Minimum Energy Performance

process load

We have currently a LEED NC project of an office building with a data center in the basement. We received the information from the electrical engineer, that the process load of the data center is 190 kW. We believe, that this is the peak load and that the average 24/7 power consumption is far below this value. Does anybody have experience with the relation between peak power and average power of data centers?

One would expect a significant diversity factor in a data center, but without more information about the actual installation, it would be hard to estimate an average. What is the purpose of the estimate? For an early energy model, I might start by assuming an actual usage of 25% of that peak, but I'd really just be guessing. If you are trying to size equipment, or have a decent estimate of energy consumption, you need more information.

30% http://www.apcmedia.com/salestools/VAVR-5TDTEF/VAVR-5TDTEF_R1_EN.pdf?sdirect=true But I wouldn't size for 30%. Chillers are designed to operate more efficiently at PLR than at full-load.
