"HVACTemplate Any Number". Overwriting existing object

[atahosseini]

Hello all

I tried to use eppy for adding some building blocks. The problem is that as soon as I reach this part of the code which is also used in the document of the "geomeppy" I get an error. I'm talking about this part:

stat = idf.newidfobject(
"HVACTEMPLATE:THERMOSTAT",
Name="Zone Stat",
Constant_Heating_Setpoint=20,
Constant_Cooling_Setpoint=25,)

and the error I get is this:

** Severe ** Duplicate name found. name: "HVACTemplate Any Number". Overwriting existing object.

idf.run(expandobjects=True) didn't solve the problem

Any help is appreciated.

What does your IDF look like? It looks like you've added two ScheduleTypeLimits objects with the same name, "HVACTemplate Any Number", but can't be sure.

Hi Jamie

I haven't defined any "scheduletypelimit". Not sure why I get this weird error

I found the problem and the solution. When eppy or "geomeppy" runs the file, sometimes, it doesn't replace the previous file with the new one. Therefore, it tries to overwrite the previous file which contributes to an error. This may be rather the EnergyPlus problem. Anyways, What I did in my code I just added a line to delete the previous file before "geomeppy" runs the file like this:

import os
os.remove("eplustbl.htm")
os.remove("eplusout.expidf")

IDF.setiddname("C:\EnergyPlusV8-9-0\Energy+.idd")
idf = IDF("C:\EnergyPlusV8-9-0\EVTEST.idf")
idf.epw = ("C:\EnergyPlusV8-9-0\WeatherData\Vancouver\CAN_BC_Vancouver.718920_CWEC.epw")
