[BLDG-SIM] Oh, what a tangled web we weave...

[Lynn Qualmann]

I am using eQuest to model an office building with 3 unique floors, many
spaces (with diff't use types) per floor and plenums between floors. I
have already defined the appropriate footprints for each floor and
imported them into a single model. NBD. Because there are many spaces
per floor and plenums assume the shape of the space they sit over, it
seemed like a good idea to import the plenums as separate, floor-shaped
spaces. This was to allow internal floors and ceilings of the non-plenum
spaces to be specified as NEXT-TO the appropriate plenum without any
concern for the shape of the plenum. If each space on, say, Floor1 had
an associated plenum reflecting the space shape, the spaces on Floor2
would not line up with those plenums. I defined neither a floor or
ceiling for the plenums so that interior floors and ceilings would be
part of the occupied spaces. As I'm sure many of you are thinking, DOE2
doesn't like that arrangement and requires at least two TILTs among the
interior surfaces, i.e. walls + floor, walls + ceiling or floor +
ceiling. If I put a floor in the 1st-floor plenum, I need to specify
which space it is NEXT-TO and the approach falls apart. Obviously, the
same deal applies to plenum ceilings. Has anyone got any ideas of how to
work around this? Is it better to just associate the plenums with the
spaces below them and let the chips fall where they may when the
separate floors are imported (i.e. can heat transfer from/to plenums be
ignored?)? Am I missing something really obvious?
 
Thanks in advance.
