[EnergyPlus_Support] EnergyPlus Macros Doubt
I was looking the EnergyPlus Macros documentation and have a doubt: can I
make a macro that automatizes a simulation serie? I mean: I'm doing a serie of
simulations that objectivates evaluate the window glass influence in a
building, but I'm also changing the north orientation and the location (with
design days and ground temperatures) of the building, like this:
- North orientation: 0; 45; 90; 135; 180; 225; 270; 315 (8 orientations on
total).
- Location: 20 brazilian cities.
- Window glass: 7 kinds.
This way I have 56 simulations on each city, that totalizes 1120 simulations
for all 20 cities. To make things easy, I wanna make an automatization like a
classic "do loop". I've already done and compilate in Q-Basic one routine that
do that, but I'm working with the .idf files and "peaces" of the .idf that are
called and inserted in the .idf file to make the final.idf, that runs in the
EPlaunch.exe.
For example: I have an .idf file ready to run, but it has no "North Axis",
"Location", "Ground Temperatures" and "Material:Windowglass" (I just cutted
then off the file). When I open the "automatic.exe" is asked to me what cities,
glasses and orientations I wanna simulate. After choose these parameters I
execute the "automatic.exe" and a serie of .bat files are called and insert the
following lines on the .idf file to make it complete and run the
"EPlaunch.exe":
