Hello, All.

I'm hoping someone out there can help me with this.

When trying to model the chilled water pumps in TRACE, I see in Appendix
G, G3.1.3.10, of course it says 22 W/gpm.

What I've done in the past (similar to what I do for the Hot Water
pumps, is sum up the Cooling Coil Capacities, use the good old
Q=500(GPM)dT, to get my GPM, and then multiply that by 22. My question
is, that if the cooling capacity is greater than 300, it's supposed to
be modeled as primary/secondary. What is the most appropriate way to
model the energy breakdown in Trace?

Thanks!
