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. </span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p>

<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>
