Thanks. It is clear now.

In my EnergyPlus model, I have created several Meter:Custum objects to sum several output variables.

Some of them [The ones that are rates and so in W units] return a warning message and the meter is ignored in the output data.

The message:

** Warning ** DetermineMeterIPUnits: Meter units not recognized for IP Units conversion=[W].
   **   ~~~   ** ..on Meter:Custom="TEST6".
   **   ~~~   ** ..requests for IP units from this meter will be ignored.
   ** Warning ** Meter:Custom="TEST6", variable not summed variable Output Variable or Meter Name="PLANT SUPPLY SIDE COOLING DEMAND RATE".
   **   ~~~   ** ...will not be shown with the Meter results; units for meter=W, units for this variable=W.
   ** Warning ** Meter:Custom="TEST6", no items assigned 
   **   ~~~   ** ...will not be shown with the Meter results. This may be caused by a Meter:Custom be assigned to another Meter:Custom.

The custom meter object:

Meter:Custom,
    Test6,                   !- Name
    Generic,                 !- Fuel Type
    *,                        !- Key Name 1
    Plant Supply Side Cooling Demand Rate;  !- Output Variable or Meter Name 1

I have used the following object to set unit conversion:

OutputControl:Table:Style,
    All,                     !- Column Separator
    JtoKWH;                  !- Unit Conversion

I would like to understand I do I get this error and the meters. Why is this? Shall I set a different unit conversion?

Why do meters for variables in W units get ignored? In my EnergyPlus model, I have created several Meter:Custum objects

I am running DOE large office reference building model in EnergyPlus, and I would like to create Monthly Cooling Maximum reports, which would include results of the sum of all cases of one type of variable.

For example: HVAC,Average,Cooling Coil Sensible Cooling Rate [W] HVAC,Average,Zone Air Terminal Sensible Heating Rate [W]

These variables are not included in the meter list (mtd) of the model.

How can I report these and other variables, sum all of them the facility level and then create outputs of the variable?

Total Cooling Rate in DOE Reference model in E+ Hello, I am running a DOE large office reference building model in Ener

Hello,

I am running sensitivity analysis of the different DOE office reference buildings (in EnergyPlus). In this analysis, I would like to compare the end-use electricity demand when the maximum electricity cooling demand end-use occurs. I want to save the minimum amount of data for each simulation; thus, I would like to avoid storing variables for each timestamp. Do you recommend to create my Output:Table:Monthly object, with cooling maximum and the remaining end uses with the advanced aggregation type option: ValueWhenMaximumOrMinimum?

Would you rather use one of the following Predefined Monthly Summary Reports:

• ElectricComponentsOfPeakDemandMonthly;
• PeakEnergyEndUseElectricityPart1Monthly;
• PeakEnergyEndUseElectricityPart2Monthly

Additionally, I would like to aggregate the daily consumption for the day of the Peak cooling demand. How could I generate this aggregation?

The Advanced Aggregation Types mention that you can aggregate monthly based on “DuringHoursShown”, parameter. Is there the possibility to look at a specific day of the year? Or I would need to check the variable on daily base output file?
