[BLDG-SIM] eQUEST- adding a roof

[Lynn Qualmann]

Kathryn -
 
As a mattter of fact, I have had a very similar experience. Were you
careful in positioning the new roof (correct vertices, tilt, facing
direction, etc) to ensure it is positioned where you want it? You can
check to see if it's in the model by viewing the wireframe 3D model and
highlighting the subject roof in the components list (if it's not in the
components list, it's not in the model). eQuest's interpretation of your
intent should show up outlined in red. Even if it's located somewhere
between the 1st & 2nd floors, it should still model the roof properly
(except for the shading - both what it shades and what shades it) as
long as it is specified as an outside wall component with the correct
tilt and is associated with the appropriate space. If that space is a
plenum that can be considered open throughout, you could break the
plenum into multiple spaces, matching one to each area that has an
exposed roof, and put a roof on each such space. Interior air walls can
be used to effectively connect the plenums thermally if you feel that
would be important, however, I'm not sure whether that may hamper plenum
HVAC returns. I used the latter approach when modeling a non-orthogonal
building with different footprints on each floor - it seemed to work.
 
Hope this helps.

Subject: [BLDG-SIM] eQUEST- adding a roof


Greetings,
I am modeling a building with a different footprint for the 1st and 2nd
stories, so I imported the CAD drawings in as 2 different shells and
managed to make it all of the way into detailed mode before noticing the
first floor is entirely covered by an exterior roof.  So, I deleted the
1st flr exterior roof, but I still need this roof in certain areas b/c
the first floor protrudes beyond the 2nd flr in a few spots and the 1st
floor roof serves as a porch floor for the second story.  I added an
'external wall' child component for those spaces and copied the existing
roof's characteristics.  Unfortunately, it is showing up as pure white
as if nothing is there and I can't figure out why or if eQUEST is
recognizing it as a roof or if it is recognizing this area as a hole.
Any experience with this? 
 
I changed the properties tab to exactly match the 2nd story roof
including answering 'yes' for shading surface.   
Any insight would be greatly appreciated!
Thanks!
Kathryn
