[Bldg-sim] ASHRAE 90.1-2013 Appendix G - Baseline Fuel Source Mapping

[Madhav Munshi]

Hello Everyone,

Does anyone know why the AHSRAE 90.1-2013 Appendix G Table G3.1.1-3 requires a Baseline HVAC system that is fossil fuel based for climate zones 3b,3c and 4-8? If my Proposed Design has an electric GSHP or VRF system, there is very little chance that the energy cost of this Proposed Design is going to be lower than a Baseline with a gas furnace/ boiler. Why does it matter for ASHRAE where the building is located and type of heating system selected for a project?

For folks in the New York, NYSERDA has amended this map to avoid this fuel switch which makes total sense.
