Hi Ben,<div><br></div><div>I agree with Nick. Also, if you have to bill match at all, which you might since this is an existing building, it is always easier to model the building as close to the design as you can. </div><div>

invest some extra time setting up the zoning geometries accurately to start.
That’s my standard practice for heavily documented projects.</span></p>

<p class="MsoNormal">Greetings everyone,</p>
<p class="MsoNormal">I am relatively new to this list, and have been using eQUEST
for only about a year. I am modeling a 3-story office building with water-loop
heat pumps, but information from the building owner, architect, and engineer
are very limited.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The WSHPs are single-zone (as far as I know) and there are
tons of them. In eQUEST, do I have to create a separate zone for each one? If I
make larger zones (eg. grouping together perimeter offices), it creates heat
pumps that are too large. Is there any way to simplify the zoning and retain
the proper heat pump size and number?</p>
