[Bldg-sim] Fossil/Electric hybrid system under 90.1 App G

[Rosenberg, Michael I]

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.

I can't seem to find reference to this in the 90.1 User Manual.  

 

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? 

 

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?

 

Thanks,
