10.0pt;font-family:Arial;color:navy'>I agree with your interpretation -- the
system would be 4-PSZ-HP – assuming you are using the 2004 edition of
ASHARE 90.1. The User’s Manual states that if the heating energy source
for the proposed building is electricity, then the heating energy source for
the baseline building has to be electricity too. This system would not actually
be used in <st1:State w:st="on"><st1:place w:st="on">Wisconsin</st1:place></st1:State>
either. Fortunately for me, the utility programs that I model for allow me to
use “engineering judgment” (common sense), so I can use a realistic
system for the baseline. But if you have to go by the book, then 4-PSZ-HP it
is! I can see how this could overstate the savings for a ground-source heat
pump system in a cold climate like ours.<o:p></o:p></span></font></p>

<br>
Anyone know what the BASELINE system should be if the design system is a ground
source heat pump? I have a non-residential building, 3 floors and <
75,000 square feet. The design system type is groundsource heat pump,
which leads to system 4-PSZ-HP, which nobody would ever choose for this climate
(Burlington, VT).<br>
<br>
Any thoughts?<br>
