<p class=MsoNormal>Hello, all.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm working on a DD-level Energy Model, and am having some
trouble with the results.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My Design Building will use campus chilled water, and campus
steam. I've modeled those per the instructions in the TRACE User Manual.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My Baseline Building is a System 7, and is therefore modeled
with a chiller (screw-chiller >150, <300 tons), and a boiler.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The overall cooling loads for the two alternatives
are:<o:p></o:p></p>
<p class=MsoNormal>Baseline: 548.1 tons<o:p></o:p></p>
<p class=MsoNormal>Design: 393.1 tons<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On the PRM Summary, however, the Space Cooling energy is
coming up at:<o:p></o:p></p>
<p class=MsoNormal>Baseline: 765.0 (10^6 Btu/yr)<o:p></o:p></p>
<p class=MsoNormal>Design: 3659.7 (10^6 Btu/yr)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It seems to me there should be an energy savings with
chilled water, over the chiller. At any rate, it seems strange to me that
there'd be an increase of Cooling Energy of 5 times, to meet a smaller load.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Might anyone have any suggestions?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
