[Equest-users] Converting Interior Walls to Exterior Walls

[Nick Caton]

I have a guess as to "how this may have happened."

 

If the corresponding shell in the wizards was ever set up adjacent to
another, the shared planes may have defaulted to "partially adiabatic,"
which would make part of your model look like it has "interior walls"
that are in fact adiabatic.

 

Rest assured, the zones behind those white rectangles are not behaving
the way it looks: as though they have your internal wall construction on
the exterior.  If you were to delete them, the 3D view would look funny,
but it would be the same as having an adiabatic wall in the same
locations (no heat transfer to/from the outside) - that could be a fast
solution.

 

The "correct" solution, to model the interaction with the exterior world
in those spaces, is to follow Katie's (well-written!) instructions
below.  Don't let her caps lock usage scare ya though - this stuff isn't
too excruciating, as long as you do keep your backups in order =).  It
may go without saying, but I'll add that you will potentially save
yourself a lot of time by spending a few minutes in your model noting
the exact name of those "interior" looking walls so that you can ctrl+F
them in the .inp file!

 

Best of luck!

 

PS: Happy to see more KC-area contributors, Katie!  =)  If you're still
having trouble finding the DOE2 files and need a quick fix, you can
download them in PDF here:  http://www.doe2.com/Download/DOE-22/  (What
you're looking for is volumes 1-6 and 2r).   I'd look at simply
reinstalling myself though, for the convenience ;).

Use the .inp file to modify those - that's the best way I know how.  The
file is located with your project - open it with notepad.  (See below).
You'll have to go find each wall and change them to = EXTERIOR-WALL and
then add the same fields (construction/height/location/shading-surface).
MAKE SURE YOU LEAVE THE TWO PERIODS AT THE END OF EACH WALL, OTHERWISE
YOU'LL MESS UP YOUR FILE.  I WOULD DO A SAVEAS ON THIS FILE BEFORE YOU
MODIFY IT IN CASE YOU MESS SOMETHING UP!!!  Save that .inp file and then
open your .PD2 file again.  Then you can update the construction types.
Hope this helps!

Good Afternoon,

 

I have two (2) of the approximately 50 exterior walls that somehow along
the way were modeled as interior walls.  The model is very close to
completion and has a many edits in detailed interface.  Is there any way
to convert these walls into exterior walls? 

 

I have never added any spaces or changed any zone layouts outside of the
wizards.  I am assuming that is what I will end up doing, but I was just
checking to see if there was a quick fix that I couldn't find.

 

Anyone have any clue how this could have happened?

 

I included a screen shot of my 3D model with the specific walls
highlighted.

 

Thank you everyone, and have a happy new year!
