<div dir="ltr">I tried running your model and actually had a different error terminate the run: <div><br></div><div><div> ***ERROR***********************************************************************</div><div> Loop: Hot Water Loop has zero design flow.</div>
<div> Check input for consistency, or specify design loads.</div></div><div><br></div><div>It looks like your VAV systems are setup with no reheat coils, which may or may not be accurate to what you're trying to model. Based on your inputs though, the only time the system would ever go into heating is when ALL the zones need heating which is rather unlikely for a VAV system serving 20 zones.</div>
<div><br></div><div>I was able to get your model to simulate properly by using reheat coils and giving it a delta T on the reheat temperature. If you don't actually have reheat, then maybe consider using a preheat coil, not a heating coil, to model the heating being done at the central air handler.</div>

<p class="MsoNormal">I’m working on a building that has a chilled water utility instead of a chilled water plant. I set up a chilled water meter to measure the economics of the system and did not specify any chillers in the system. When I run the simulation
the detailed simulation output file gives an error saying “Chilled water loop has no attached primary cooling equipment,” any thoughts out there as to why I am getting this error. I attached my .inp file to reference.<u></u><u></u></p>
