<div class=Section1>
<p class=MsoNormal>I’m working on a model of a 5-story building –
my Proposed system is floor-by-floor chilled water AHUs connected to a
water-cooled chiller central plan. Airside is shutoff VAV boxes with hot
water reheat.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For the size of the building, the baseline model is almost
identical. It is System 7 – Packaged rooftop VAV system with reheat
boxes, chilled water, hot water boilers.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My question is whether or not the Baseline model has to have
a single system for the building, or should it have 5 separate RTUs (doesn’t
really make any sense) since my proposed building has 5 systems?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m pretty sure the answer is that the Baseline should
just have one packaged RTU for the building, but it actually makes a big
difference on energy use. By breaking the systems down into
one-per-floor, as is the case with the proposed model, I end up saving a LOT of
energy, possibly because the 1<sup>st</sup> floor is slab-on-grade, and the 5<sup>th</sup>
floor has a roof. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Just wanted to make sure I have the correct number of “systems”
for the Baseline model.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks!<o:p></o:p></p>
