<p class=MsoNormal>Hello Everyone,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In preparing a baseline simulation, I have noticed the “Pump
& Auxiliary” energy is higher than anticipated. The only circulation
loops included in the building are HW and DHW. DHW does not include a pump. Heating
is provided using gas boilers and HW coils throughout the building. The 6.65
kW HW pump is controlled using a VFD. The hourly reports for “Pump &
Aux.” energy indicate a non HW Pump load that I cannot account for. The
load does appear to modulate with the heating load. I have included a graph of
the hourly reports for “Pump & Auxiliary” and HW pump
electricity use below. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone know what equipment would be included for “Pumps
& Auxiliary” energy use, in addition to the HW pump?<o:p></o:p></p>
