in the BEPS/BEPU reports. The exceptions that come to mind are crankcase heater energy (assigned by default to air-cooled condensers) which is included in “PUMPS & AUX” and supplemental heating which, not surprisingly, is included in “HT PUMP SUPPLEM”. Energy
from pumps assigned to the ground loop and heat pump loop appears in “PUMPS & AUX”.<o:p></o:p></span></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Calibri","sans-serif"">Hi all,<br>
<br>
I just have a question about how sizing the Groundloop in Equest works.<br>
<br>
<br>
Question 1:<br>
How does eQuest Size the ground loop (Ground-Source Heat pump for example). Does the user have to specify "the length of the ground loop" or is there an option to auto-size to meet all of the buildings heating/cooling demands.
<br>
<br>
Question 2:<br>
Does eQuest consider "heat produced by the heat-pump for the ground loop and other heating and cooling equipment" as part of the "Total cooling/Heating Demands" in the output?<br>
<br>
<br>
Thankyou very much<br>
<br>
<br>
