Broken idf

[amaliahicks]

Hi there,

Eppy is fabulous, thank you for creating it. I am having a slight problem with it breaking my idf file, however. I have a 3 story building with about 17 zones per floor. Each zone is included in a water outlet group, so in total I have 51 pieces of water use equipment.

When I run eppy on my input idf, it only transfers 10 pieces of water use equipment to the resulting idf file (under the WaterUse:Connections object). Subsequently, when I try to run the new idf file in E+ it crashes.

Any suggestions you could send along would be much appreciated. I can cut and paste the rest of the water use equipment into the new idf file, but that kind of cuts into eppy's usefulness...

Thanks so much for your help,
Amalia

You need to modify the IDD file that Eppy is using to add additional copies of that repeating field.

C:\eppy046\resources\iddfiles

Thank you!!! That makes sense. Can I use the same IDD file for other
models that don't have that many pieces of water equipment, or is it
important to have a customized IDD file for each model?

While I've got your attention, I'm also having trouble getting eppy to
print a single object from a list. I can print the entire list just fine,
but when I try to just print one element I get errors. Here's a snippet
from the code:

LPD

lights = idf1.idfobjects['LIGHTS']
for light in lights:
light.Design_Level_Calculation_Method= "Watts/Area"
light.Lighting_Level=""
light.Watts_per_Zone_Floor_Area="8.61112"

firstlight = lights[0]

print firstlight

Thanks so much!!!
Amalia

Amalia,
I thought it would print. Will take a look and check. I am traveling now, so my response may be slow.

Amalia,
You can use the modified IDD for on your other models too

I am unable to recreate the front problem,
If it reoccurs open a new issue with the error message it is throwing out.

I am closing this issue
