<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The proposed model(design) has floor level AHU’s of type ‘PIU’ with terminal Fan powered boxes at the perimeter zones and terminal VAV boxes at interior core zones. The reheat at core
zones were manually made zero because of the core zones require only cooling and that way it remains true to the design.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The baseline model has floor level AHU’s of type ‘Variable Air Volume’ with reheat temperature given at the system level( not possible to give a reheat temperature at zone level).
<o:p></o:p></li></ol>
<p class="MsoNormal">Results show that the baseline heating is way worse than the proposed( by 40%) which doesn’t seem right.<o:p></o:p></p>
<p class="MsoNormal">Core zones in the baseline model have a heating demand( confirmed through SV-A summary report) which may be the reason for the increased heating energy use.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please advise if the system types selected are the right one’s for the baseline model. And if it is right to have assigned a reheat at the system level which makes it to assign a reheat for the core zones automatically in the baseline model.<o:p></o:p></p>
