# eQuest coordinate system question

Hi!
So I’m working on a honeybee exporter, to export doe2.inp files.
I have a question, if anyone happens to know:
in DOE23Vol3-Topics_50e.pdf:

``````FLOOR, SPACE, EXTERIOR-WALL, INTERIOR-WALL,
WINDOW, AND DOOR GEOMETRY
This section describes how to specify the location, orientation and size of a building’s floors, spaces, walls, windows
and doors. It also describes how to locate the building itself and its exterior shading surfaces.
Coordinate Systems
The LOADS program uses a hierarchy of four right-handed Cartesian coordinate systems:
• the building coordinate system
• the floor coordinate system
• the space coordinate system
• the wall coordinate system
These systems are related to each other by translation and rotation. In addition, a reference coordinate system is
used to locate the building and fixed shades when fixed shades are present (see FIXED-SHADE command).
A floor coordinate system is defined relative to the building coordinate system. A space coordinate system is defined
relative to a floor coordinate system; a wall coordinate system is defined relative to a space coordinate system.
Windows and doors are located with respect to a wall coordinate system.
There is only one building coordinate system, but there is a floor coordinate system for each floor, a space
coordinate system for each space, and a wall coordinate system for each exterior wall, interior wall or underground
wall. You don’t have to keep track of the overall position of each wall and window/door relative to the building as a
whole. Instead, the position of walls is specified relative to the space in which they occur, and the positions of
windows and doors are specified relative to the wall on which they occur. The program then automatically
transforms the walls and windows to the overall building coordinate system.
You define the building coordinate system in the SITE-PARAMETERS command by assigning values to the
keywords AZIMUTH, LATITUDE, LONGITUDE and ALTITUDE. The other coordinate systems are located
as follows:
1. A floor and its coordinate system are located in the building coordinate system by assigning values to
X, Y, Z and AZIMUTH in the FLOOR command.
2. A space and its coordinate system are located in the floor coordinate system by assigning values to X,
Y, Z and AZIMUTH in the SPACE instruction.
3. A wall and its coordinate system are located in the space coordinate system by giving values to X, Y,
Z, AZIMUTH and TILT in the EXTERIOR-WALL, INTERIOR-WALL or UNDERGROUND-
WALL command.
4. A window and its coordinate system is located in an exterior wall or interior wall coordinate system by
assigning values to X and Y in the WINDOW command. Windows that are recessed from the surface
of exterior walls can be further located by assigning a value to SETBACK in the WINDOW
command. A door and its coordinate system are located in the exterior wall coordinate sytem by
assigning values to X and Y in the DOOR command.

Does anyone know if there is a means to ‘toggle’ this four level coordinate system off as to use global coordinates?

You should probably ask this in unmethours or the eQuest mailing list.

(in all seriousness is the eQuest mailing list… the kind of mail that takes a stamp?)

good point! I actually forgot about unmet hours
