size=2>Yes, you are correct. Appendix G requires that if you have any gas heat
in your Proposed building, the baseline system would use gas heat. However, if
this is for a LEED submittal, you may want to do a little research on relevant
CIR's since USGBC has interpreted this a little differently than was intended by
Appendix G. </FONT></SPAN></DIV>

hybrid system under 90.1 App G<BR></FONT><BR></DIV>

<DIV class=Section1>
<P class=MsoNormal>I can’t seem to find reference to this in the 90.1 User
Manual. <o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>In Appendix G, Table G3.1.1A, there is a reference to a
Fossil/Electric hybrid for determining Baseline system type. Is this a
system that, for example, might have a gas-fired RTU with electric VAV boxes?
<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>In other words, if there is ANY gas heat in your Proposed
building, your Baseline building would have to automatically default to a fuel
furnace or gas-fired hot water heating system, correct?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Thanks,<o:p></o:p></P>
