RESFEN 5 does not model electric resistance heating, but rather models the
buildings with a Furnace+AC system and then converts the energy consumption
using expected heat pump performance to determine final electric consumption. I
<i><span style='font-style:italic'>think </span></i>what you came across is the
conversion from the furnace system to the heat pump system. The website also
takes into account the efficiency of the furnace as it reverse-engineers the
expected heat pump consumption. The efficiencies are 70% for existing
construction and 78% for new (which are similar to the numbers you came up with).<o:p></o:p></span></font></p>

With the caveat that I am not a programmer or a developer and with some
trepidation I will say I think I know where you should go at least. The first
part is a programming language, see above, but the last part looks like DOE2
BDL. It is probably from DOE2.1e since it's from LBNL. So going way back in the
memory banks and scrolling down, down, and further down there is something
labeled:<o:p></o:p></span></font></p>
<pre><font size=2 face="Courier New"><span style='font-size:10.0pt'>##if #[Vintage[] eqs New ]<br>
<br>
<o:p></o:p></span></font></pre><pre><font size=2 face="Courier New"><span

style='font-size:10.0pt'> FHIR=1.5015 CEIR=.41667 <o:p></o:p></span></font></pre>
<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'><br>
I'm pretty sure that FHIR is what you want and if my memory serves, a big if,
it represents 1/eff so the first one, age New, would be 79.7%, and the second
one, age Exist, would be 66%. Since this kind of makes sense, I might be right!
If I'm not, hopefully someone who knows more will correct me.<br>
<br>
Maybe you can verify this by changing it. I've never used RESFEN myself.<br>
<br>
Let me know what happens.<br>
