<div class="yiv508262048MsoNormal">Hi All,</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">I am trying to model a package roof top VAV unit with electric heat coil.</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">At system level heating I selected:</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">System type: Pkgd Var Val</div>
<div class="yiv508262048MsoNormal">Heat source: furnace</div>
<div class="yiv508262048MsoNormal">Zone heat source: Electric (each zone has a VAV with electric heat coil, EAT=55, LAT=85)</div>
<div class="yiv508262048MsoNormal">Heating capacity:-220 MBH (same as my mech sch. For RTVAV)</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">At zone level I think I have to enter heating capacity or reheat delta T, but both of them are n/a.</div>
<div class="yiv508262048MsoNormal">How can I get this one fix?</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">On my previous model, I modeled the electric heat coil as a baseboard in each zone!!!</div>
<div class="yiv508262048MsoNormal">I am not sure if I did it correctly because at the end my space heating on baseline was very low compare to proposed and made energy saving percent equal to -97%.</div>
<div class="yiv508262048MsoNormal"> </div>
<div class="yiv508262048MsoNormal">Thanks in advance for your help</div>
