Hello,

I'm modelling a low-rise data center. According to Appendix G, I should use system 4 (rooftop package heat pump) for reference model. My question is: should I assign a system 4 to every conditioned thermal zone - data hall, ancillary office, corridor, UPS room, etc.?

Thanks.

G3.1.1: "For systems 1, 2, 3, and 4, each thermal block shall be modeled with its own HVAC system".

Thanks. I could have elaborated the question more. Appendix G also says that if the load differs, exception can be made. The data hall load is much higher than the rest thermal zones. Do I still apply system 4 for all zones? Can I keep the design system for the ancillary spaces?

What exception? Exception b is not valid for System 4.
Regards
