I assume that you are working from the example of using GenOpt and
TRNSYS with Type56
(<a class="moz-txt-link-freetext" href="http://sel.me.wisc.edu/trnsys/demos/genopt-type56.pdf">http://sel.me.wisc.edu/trnsys/demos/genopt-type56.pdf</a>). If not, that
will give you some good direction.<br>
<br>
If I understand correctly what you are trying to do, you need to
identify the material properties of your outside wall with variable
names that will be replaced by GenOpt in the *.bui file at each
simulation run. It might look something like:<br>
<br>
<small><font face="Courier New, Courier, monospace">*--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------<br>
* L a y e r s<br>
*--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------<br>
LAYER GYPSUM<br>
CONDUCTIVITY= 2.62 : CAPACITY= 0.75 : DENSITY= 1601<br>
LAYER INSULATION<br>
CONDUCTIVITY= <font color="#3333ff">%kInsul%</font> : CAPACITY= <font
color="#3333ff">%capInsul%</font> : DENSITY= <font color="#3333ff">%rhoInsul%</font><br>
LAYER STUCCO<br>
CONDUCTIVITY= 2.49 : CAPACITY= 0.75 : DENSITY= 1858</font></small><br>
<br>
You also need to define something to minimize and that will probably
not change from the example. The example uses the integrated
whole-building annual energy use as its minimization variable. You can
follow section 5.2.4 in the *.pdf.<br>

<pre wrap="">Hi all,
I want to minimize the total energy-consuming of a building by varying
the thermal characteristics of the outside wall (density, thermal
conductivity and specific heat). I use GenOpt and TRNSYS for that but
I encounter some difficulties. I refered to the given example and I
started with the same building modelisation for my problem.I do not
know how integrate variables for density, thermal conductivity and
specific heat in .bui template file.
Could someone help me please ?
Best regards,
Didier Gossard from France.
