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

[Mitchell Dec]

There is a CIR floating out there from a LEED-CS project that states the
baseline building can have electric reheat. However, the modeler is to
match the total therms of natural gas consumed for the gas-fired RTU in
both the baseline and as-designed models.

Subject: [Bldg-sim] Fossil/Electric hybrid system under 90.1 App 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,
