Hello,

In November 2010, around the same time someone was modeling a building that looked like a turkey, there was a conversation on this list about baseline CHW pump power:

Part of the discussion was some back and forth about how to apply G 3.1.3.10. This section calls for baseline pump power to equal 22W/GPM and for the CHW pumping configuration to be primary/secondary. Some had the opinion that each pump (primary and secondary loops) should have 22 W/GPM assigned to it, while others thought that the total CHW pump system power should sum to 22 W/GPM, and that it was up to the modeler to divvy up the power among pumps as they see fit. I did not see a clear conclusion.

Does anyone know if a general consensus was reached?

Thanks,
