<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Thank you both for looking at this. I'm a bit dumbfounded that it
can't be as easy as the fact that I need to specify reheat, since I have
indicated that it is a VAV with reheat system, but if that is the case then I
will re-instate the reheat delta t so that I can generate heating energy.
(when I had input a reheat delta t of 30 degrees F, I was able to successfully
fun a simulation, but the heating energy numbers where so high (i.e. 30 kWH/sq
ft or more) that it just didn't seem like this was the correct input for my model.<o:p></o:p></span></font></p>

only way I can get heat out of the heating coil is that I have to enlist reheat

is a requirement in DOE to have some or ll of the heating capacity specified

be passed to the systems module only if reheat or baseboards are specified.<o:p></o:p></span></font></p>

input requirement I would like to hear thier feedback. In the meantime,
what I am understanding is that it is a requirement to specify
supplementary heating (i.e reheat or baseboards) in DOE2 for a VAV
reaheat system before DOE2 will allow a basic heating coil to assume a heating
load...somebody please tell me I'm wrong-because this doesn't make sense.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Tahoma><span style='font-size:10.0pt;
font-family:Tahoma'>I took a look at your model. When employing a VAV-Reheat
System as you have in your model, you must also specify the reheat Delta-T for
the zone heating coils attached to the units (see attached screenshot). If this
is not done, the program assumes that the zones have no reheat, and thus will
never put a load on your hot water loop. This, in turn, causes the
error that you've seen. The DOE-2 documentation describes it as follows:</span></font><o:p></o:p></p>

<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>Maximum
increase in temperature for supply air passing through the zone (or subzone)
reheat coils. The value specified here applies to all zones in the system. This
keyword is required in order to simulate heating the air as it passes through
the terminal reheat coil. Note that when very little air is passed (see
MIN-FLOW-RATIO) there may be insufficient reheating.<o:p></o:p></span></font></p>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'> <o:p></o:p></span></font></p>
<p><font size=2 face=Tahoma><span style='font-size:10.0pt;font-family:Tahoma'>According
to your model, the maximum zone entering supply air temperature is 105 degrees.
I also noticed that your zone minimum entering supply temperature is 55
degrees. As such, you need to specify your reheat delta-T as 50 degrees (as in
the screenshot). This ensures that your zone coils are able to raise the
55-degree air from the AHU up to the 105 degrees that you have specified.
Try that, and your model should run just fine.</span></font><o:p></o:p></p>
