<DIV><SPAN class=163352514-29112007><FONT face=Arial size=2>I have an air-to-air
electric heat pump with a gas powered duct furnace. Is there anyway to
accurately account for this in the eQuest wizard? (I'm still in preliminary
stages of project) </FONT></SPAN></DIV>

<DIV><SPAN class=163352514-29112007><FONT face=Arial size=2>This is what I
tried. I entered the system as a split system single zone heat pump with
air as the source. But when I entered the heating capacity and efficiency
I entered it as an effective value factoring in both the heat pump heating and
duct furnace. Htg Capacity= Heat Pump Cap + Duct Furnace Cap, Htg
Efficiency = (HP Cap * COP + DF Cap * Efficiency of DF)/Htg
Capacity</FONT></SPAN></DIV>

<DIV><SPAN class=163352514-29112007><FONT face=Arial size=2>One thing that I'm
worried about is that I'm eliminating the consumption of gas, and thus may be
skewing my savings. Does anyone have suggestions?</FONT></SPAN></DIV>

<DIV><SPAN class=163352514-29112007><FONT face=Arial size=2>One other thing that
I had a question about is if what I did is acceptable, then should I use an all
electric baseline HVAC or keep the fossil fuel type system, even though I'm not
actually modeling any gas use.</FONT></SPAN></DIV>
