Hi Seth,<br><br>Go to the Air Side HVAC System Parameters screen. Do not put a sizing ratio on the first screen, i.e., the Basics tab. Instead go to the Cooling tab, and down to where it says Cool Sizing Ratio (you saw this one); then go to the Heating tab, and down to where it say Heat Sizing Ratio. That should get you what you want.<br>

<p class="MsoNormal"><span style="font-size: 10pt;">Hello,</span></p>

<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>

<p class="MsoNormal"><span style="font-size: 10pt;">I’m
modeling a system that consists of a packaged VAV w/HW reheat for my baseline
model. I am currently over-sizing the systems per 90.1. I oversized the cooling
capacity using the “Cool Sizing Ratio” in detailed edit but I am
unable to figure out an “easy” way to oversize the heating capacity.
This option does not show up for heating at the AHU or zone level.</span></p>

<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>

<p class="MsoNormal"><span style="font-size: 10pt;">Can
someone enlighten me on how to oversize my heating capacity by 25%.</span></p>

<p class="MsoNormal"><span style="font-size: 10pt;"> </span></p>

<p class="MsoNormal"><span style="font-size: 10pt;">Thanks</span></p>
