<div>Peter--I can help you with this, you're on the right track, but Yes-being Friday I too am feeling lazy for the weekend, not wanting to type you a whole page of info. Give me a call and I'll talk you through it. I'm available now.</div>

<p class="MsoNormal">I have found with my own projects that even sometimes when the HVAC designer has specified a specific capacity for htg water equipment that sometime in my model file I still have unmet loads for htg. I suggest at this point specify additional htg capacity by either increasing the reheat delta-T from say 30F to 50F and/or adding zone level baseboards. By adding the baseboards you are adding a component of the system that will supplement the skin losses being experienced by the simulation model.</p>

<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">by adding baseboards for the additional requrired heat then you should be able to meet your heating loads.</p></div>

<p class="MsoNormal">All:</p>
<p class="MsoNormal">I have completed an energy model for a baseline scenario from which to compare my proposed design. The baseline HVAC system is a constant volume single zone AHU w/ no reheat; the AHU is served by HW and CHW loop from a central plant. I have set this up in eQuest as a "Variable Air Volume" system type with the AHU fan control set to "Constant Volume"; my thought here is that each zone fed by the AHU will control temperature using a VAV box w/ no local reheat or cooling. Flow and temperature from the AHU will be delivered based on the coolest or warmest zone it serves.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">All seems fine with the design flows, ventilation flows and cooling capacities. My problem is with the heating capacity as I have excessive unmet heating hours (50,000). I have allowed eQuest to size the heating capacity of the preheat and heating coil as well as the minimum flow ratios. <u>Does anyone have any thoughts as to what is causing these unmet heating load hours? Is the way I have set-up the desired baseline HVAC system incorrect?</u></p>
