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).</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:</span></font></p>
<pre><font face="Courier New" size="2"><span style="font-size: 10pt;">##if #[Vintage[] eqs New ]<br>
<br>
</span></font></pre><pre><font face="Courier New" size="2"><span style="font-size: 10pt;"> FHIR=1.3550 CEIR=.3703 <br>
<br>
</span></font></pre><pre><font face="Courier New" size="2"><span style="font-size: 10pt;">##elseif #[Vintage[] eqs Exist ]<br>
<br>
</span></font></pre><pre><font face="Courier New" size="2"><span style="font-size: 10pt;"> FHIR=1.5015 CEIR=.41667 </span></font></pre>
<p class="MsoNormal" style="margin-bottom: 12pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"><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>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I have a question
about RESFEN that I’m hoping this list can help me get my head around.
RESFEN is developed and maintained by LBNL and I believe runs off the DOE2
engine. The software is simple to use because of its limited inputs, however I
want to change one of those restricted inputs.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I’m trying
to change the boiler performance which I <i><span style="font-style: italic;">think
</span></i>I can do by editing the building description file (which RESFEN
labels as a .d2 file). I’ve attached the file and saved it in a .txt
format for all to see.</span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">My question is:
Can someone proficient in the DOE2 language help me decipher where and how to
edit the efficiency of the boiler in the attached file? I don’t know the
part load, just that the boiler in question operates at 60% efficiency. If this
is to broad a question please let me know and I will attempt to clarify.</span></font></p>
