Hi, I am just wondering if we can create Meter:Custom using EnergyPlus/OpenStudio Python API. If yes, importing key and variable names from a csv file would be more convenient. I didn't find any relevant examples. Thank you for your help.
Why couldn't you? If the SDK has an object, the ruby and the python bindings have it too (very rare exceptions aside)
SDK Documentation: MeterCustom Class Reference
Ruby example of API: OpenStudio-Resources: meters.rb#L68-L88
Python works EXACTLY the same, syntax aside.
In [1]: import openstudio
In [2]: m = openstudio.model.exampleModel()
In [3]: meter = openstudio.model.MeterCustom(m)
In [4]: meter.setFuelType("Electricity")
Out[4]: True
In [5]: for l in m.getLightss():
...: meter.addKeyVarGroup(l.nameString(), "Lights Electricity Energy")
In [6]: for e in m.getElectricEquipments():
...: meter.addKeyVarGroup(e.nameString(), "Lights Electricity Energy")
In [7]: print(meter)
OS:Meter:Custom,
{22211bf0-8e18-4956-9e3c-3038f8e7723e}, !- Handle
Meter Custom 1, !- Name
Electricity, !- Fuel Type
Lights 1, !- Key Name 1
Lights Electricity Energy, !- Output Variable or Meter Name 1
Printer, !- Key Name 2
Lights Electricity Energy, !- Output Variable or Meter Name 2
Electric Equipment 1, !- Key Name 3
Lights Electricity Energy; !- Output Variable or Meter Name 3
I've figured out the question. Let me ask and answer myself. I am using OpenStudio Python API.
import csv
import openstudio
def create_meter_customs_from_csv(csv_file_path, model):
meter_dict = {}
output_meter_dict = {}
with open(csv_file_path, 'r') as csvfile:
csvreader = csv.reader(csvfile)
next(csvreader) # Skip the header
for row in csvreader:
meter_name, fuel_type, key_name, output_variable_or_meter_name = row
if meter_name not in meter_dict:
meter = openstudio.model.MeterCustom(model)
meter.setName(meter_name)
meter.setFuelType(fuel_type)
meter_dict[meter_name] = meter
# Create and configure OutputMeter for the same MeterCustom
output_meter = openstudio.model.OutputMeter(model)
output_meter.setName(meter_name)
output_meter.setReportingFrequency('timestep') # Options: 'detailed','timestep','hourly','daily', 'monthly'
output_meter_dict[meter_name] = output_meter
meter = meter_dict[meter_name]
meter.addKeyVarGroup(key_name, output_variable_or_meter_name)
print(f"Meter:Custom objects created: {list(meter_dict.keys())}")
print(f"Output:Meter objects added: {list(output_meter_dict.keys())}")
# Usage
model = m # Replace this with your OpenStudio model
create_meter_customs_from_csv('csv_file_path', model)
