color:#1F497D'>First you have to pull out the loop/pump flow from the PV-A
report, then multiply by 19 W, and enter that as the pump KW. I think you
also have to set the pump/motor efficiencies to 1.0 since the ASHRAE 90.1 value
of 19 W / gpm should automatically include losses. Someone feel free to
correct me on that if it’s not right.<o:p></o:p></span></p>
