[Bldg-sim] Appendix G Baseline Systems

[Mark Sorensen]

Greetings All,

I have the following question regarding ASHRAE 90.1 Appendix G baseline 
systems; For a building with proposed electric water source heat pumps 
utilizing a building loop tempered by a natural gas fired boiler (during 
the heating season) would the correct baseline heating type be fossil 
fuel or electric?
