Re: [EnergyPlus_Support] ASHRAE 90.1-2007 App G G3.1.3.2 boiler sizing

Okay, so this is also analogue for Chillers. As for the pumps, I am betting the same, i.e . each with its own pump interlocked to the boiler it serves. The pumping power is specific. I'm unsure, but suspect that two smaller less efficient parallel pumps staged with capacity would be more efficient than one large pump operating at low part loads most of its time where it is even less efficient.
