<div>Hi Umesh,</div>
<div> </div>
<div>thanks for your attention to my issue. Unfortunately because this is a baseline case I can only put in pre-heat if my proposed design has it, and my case does not. What I thought was interesting in my case was that the preheat & baseboard inputs were showing heating energy consumption, but the AHU & HW coil was not showing any heating energy---I have know learned that because I didn't have the T-stat schedule input this was not offering the "call for heating" that the AHU was looking for.</div>
<div> </div>
<div>At some point when I switched my project from Wizard to DDedit mode (& changed my HVAC system type from chosen in the Wiz) so I went through the input spreadsheet and "reset" the inputs back to default since I had changed from an initial FC system selected in the wizard. I didn't realize that by "re-setting" the t-stat schedules they didn't default to a common schedule, they just defaulted to nothing---so nothing was what I got.</div>
<div> </div>
<div>this is a great simulation community and resource where we can all support and help each other learn and learn from others' trials & troubles. keep the communication flowing...</div>

<div>Thanks James. I do have an additional HW loop pump...but I will take a look at the thermostat schedule stuff.</div>

<p class="MsoNormal">Thanks John--I hadn't input the reheat delta t, thinking that it was one of those "blank" default auto-calc things.... so by inputting a 30 deg delta, that took away the error in the bdl file, but the results are still not showing any space heating consumption and yet somehow I have 0.0 hours out of throttling range---I thought this had to be too good to be true.</p>

<p class="MsoNormal">Hi all,</p></div>
<div>
<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">I thought I was wrapping up my baseline model and then for some reason I discovered that the only heating energy being used is going through the zone baseboards. When I take out the baseboards, the results show a big fat ZERO for any space heating energy the DOE2 error shows below. How can the design loads not get passed to the system. The baseline systems are VAV with reheat, but for some reason there is no heat or reheat unless I specify pre-heat (which there is none) or baseboards... any ideas are appreciated--because I thought I was closer to finished with this model until this issue popped up.</p>
