<p class="MsoNormal">Hi all,</p>
<p class="MsoNormal">I’m working on the LEED project. My high rise residential building is modeled as system 1 (baseline) and chilled water system (propose)</p>

<b>constant volume</b> for system 1 (Package DX Fan coil) . I want to know how to set the control (<b><span style="color:red">Fan on</span></b><span style="color:red">
</span>or <b><span style="color:red">fan cycled</span></b>). If I choose the <b><span style="color:red">Fan on</span></b><span style="color:red">

<p class="MsoNormal">EFLH is determined by dividing the total annual fan consumption by the total fan power in the HAP report.</p>
