eQuest Coordinates

Dear eQuest users,

I need to read the absolute coordinates of the origin of each space (the
coordinates of each space origin with respect to the origin of the building
coordinate system) from the .inp file that eQuest creates. I need
to do this so that I can locate the spaces side by side or one over the
other in the correct order in another program. I checked whether the X, Y
and Z commands were used under the SPACE command of the DOE-2.2 inp to
figure this out. But, it turns out that the DOE-2.2 input file does not
have the X, Y, Z commands used for the spaces. Below is an example SPACE
command in the DOE-2.2 input (.inp) file that eQuest creates. Would you
please let me know which command in the .inp file below would be helpful
for me to extract the information necessary to locate the zones correctly
with respect to the building origin?

"L1 Zone3" = SPACE
SHAPE = POLYGON
ZONE-TYPE = CONDITIONED
PEOPLE-SCHEDULE = "EL1 Bldg Occup Sch"
LIGHTING-SCHEDUL = ( "EL1 Bldg InsLt Sch" )
EQUIP-SCHEDULE = ( "EL1 Bldg Misc Sch" )
INF-SCHEDULE = "ZG1-S1 (PSZ) P-Inf Sch"
INF-METHOD = AIR-CHANGE
INF-FLOW/AREA = 0.0277204
PEOPLE-HG-LAT = 250
PEOPLE-HG-SENS = 250
EQUIP-LATENT = ( 0 )
EQUIP-SENSIBLE = ( 1 )
PEOPLE-HEAT-GAIN = 417
LIGHTING-W/AREA = ( 1.5 )
EQUIPMENT-W/AREA = ( 1 )
AREA/PERSON = 100
POLYGON = "EL1 Space Polygon 3"
LOCATION = FLOOR-V44
C-SUB-SRC-BTUH = ( 0, 0, 0 )
C-SUB-SRC-KW = ( 0, 0, 0 )
C-ACTIVITY-DESC = *Classroom / Lecture (70%)*
..
"EL1 West Wall (G.W3.E6)" = EXTERIOR-WALL
CONSTRUCTION = "Wall Const"
LOCATION = SPACE-V1
..
"EL1 West Win (G.W3.E6.W1)" = WINDOW
GLASS-TYPE = "All G-Type"
FRAME-WIDTH = 0.108333
X = 1.98833
Y = 3.10833
HEIGHT = 5.00333
WIDTH = 3.78333
FRAME-CONDUCT = 2.781
..
"EL1 Roof (G.W3.E7)" = EXTERIOR-WALL
CONSTRUCTION = "Roof Const"
LOCATION = TOP
..
"EL1 Flr (G.W3.U3)" = UNDERGROUND-WALL
CONSTRUCTION = "Floor Const"
LOCATION = BOTTOM

Thank you very much in advance for your help,
Looking forward to hearing from you,

Best Regards,
Simge Andolsun, Ph.D., M.S.

You could look at the LV-N Building Coordinate Geometry report, which is the first report
in the *.SIM file that lists the vertex coordinates for all the spaces and surfaces.
However, if you're trying to build an EnergyPlus IDF by parsing the LV-N, that would take
a lot of time for anything more complicated than a shoebox, plus you will still only have
the building geometry inputs.

What I have done to translate from DOE-2.2 to EnergyPlus (assuming that's your ultimate
need) is to change 2.2 to 2.1E BDL using a collection of awk scripts, use the doe2ep
program that I worked on while still at LBNL to translate the 2.1E BDL to EnergyPlus 3.0
IDF, and then use EnergyPlus' MultipleVersionTranslator to upgrade to the current version.
Believe it or not, but this has actually worked for several projects I've been involved.
This is clearly an interim solution, and not something I would be comfortable in releasing
as software. However, if anyone's interested, please contact me at the e-mail address
shown below.
