<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>I
am trying to model a large building with heating and no cooling. The
heating is constant volume. 90.1 Appendix G says I need to model the
baseline system as a VAV system with heating and cooling, and that I need to
include the baseline cooling system in the proposed building.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>Trace
700 does not allow “divorcing” the heating from the cooling, which means I
will end up with a VAV heating system. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>Trane
CDS is saying that this is what I have to do. I accept the need to have a
VAV cooling system, but being forced to have the heating as VAV means the
energy differences between the proposed heating and the 90.1 minimum heating
system will not be calculated since they are the same.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>My
question is, how do I model the heating system as constant volume and have the
VAV cooling system? Has anyone had this problem and did you just live
with it?<o:p></o:p></span></p>
