[Bldg-sim] fossil hybrid or electric

[Morgan Heater]

Hi - I've got an appendix G baseline system question.  Here's the
scenario, let me know what you think.  

 

Proposed Building:

 

1.       Multi-family residential, amenity/common space < 20,000 square
feet

2.       Electric baseboard heat in the units

3.       Condensing gas furnaces in the corridors and back of house spaces

4.       VRF in amenity common spaces

 

My understanding is that because my non-predominant condition
(common/amenity space) is less than 20,000 square feet, I use a single
system for the whole baseline building (G3.1.1a).  I've got a mix of gas
and electric heat in the baseline building,  does this mean that my base
system is PTAC with a hot water boiler?

 

Thanks!
