<p class="MsoNormal"><span style="color:#1F497D">Not sure if I missed a response to this or not…sorry this got lost in my draft folder for a few days.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">What you’ve stated as the problem is exactly why the standard takes the other approach – if the baseline system costs less to operate (and may also have lower source energy) then why shouldn’t it be the baseline
system?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The standard is looking to establish the minimum requirements, which shouldn’t be “Best Practice” necessarily but reflect a constantly advancing minimum threshold.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Choosing to use a system that’s less cost efficient is certainly allowable and, but requires making other improvements in the building to offset what is traded off by using the electric resistance heating system.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Note that while the requirements of the standard do change based on climate, it isn’t based on geography directly, I have understood in the past that the approach is for national average utility rates to set
the requirements. I can think of several reasons why NYSERDA specifically would take a different approach, but in general for country-wide adoption I would expect gas heat to be the reasonable baseline in climate zones that need more heating. Is it debatable
for zones 3b and 3c, perhaps. I’m pretty comfortable with fossil fuel baseline in CZ 4-8.<o:p></o:p></span></p>

<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">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? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">For folks in the New York, NYSERDA has amended this map to avoid this fuel switch which makes total sense.
