<p class=MsoNormal>I do have specified 105 supply temp, 105 hot deck max temp,

when I set up the model using the wizard initial inputs they were for the

all spaces including thermal displacement vent, natural vent zones (for htg
baseboards), FC's etc. So----I am wondering if when I saved my file for
the baseline model and then switched the plant equip (chiller/boiler) & VAV
sys if there is a carry-over input from the HPsystems (or other) that is
affecting the lack of heating energy with the standard systems.<o:p></o:p></p>

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></p>

understand the logic of why this works, but I don't understand why it is a

to "autosize" or react to the fact that heating loads need to be

am understanding is that it is a requirement to specify supplementary

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

the zones have no reheat, and thus will never put a load on your hot water

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><o:p></o:p></p>
