FAQs about EAc2 :

The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

Data-Centers-NC-v4 EAc2:Optimize energy performance

Number of chillers in Energy Model

Hi, I am currently preparing an energy model for a data center project (system 8). Since the process load is very high, 22 chillers and cooling towers are required if I stick to the requirement in Appendix G Table G3.1.3.7 which states that no chillers shall be sized larger than 2813kW. Have I missed something, perhaps an exemption somewhere, because this seems a bit odd.

It depends. Cooling a data center could be considered a process load. If the cooling system cools the equipment directly it might be considered a process load itself. Then it would be modeled identical to the proposed.
