Is it possible create a table for electric equipment, like a Report:LightingSummary?

What I'm looking for is an output table showing annual consumption for the individual items of electric equipment such as those shown in the image below.

I'm using OpenStudio 1.8.0 and EnergyPlus 8.3.

I think what you're looking for is the ElectricEquipment object's End-Use Subcategory field which will create a new row in the End Uses by Subcategory table in the tabular output HTML file. Additionally, a row will be created in the Energy Meters table for each subcategory you create.

By default this field is set to "General" and can be found in OpenStudio in each instance of the object but is not editable as of 1.8.2. The easiest way to edit the field is in the SketchUp Plugin through the Inspector.

@MatthewSteen I am using Sketchup 16.0.19912 and OpenStudio 1.11.3 and do not see OS:ElectricalEquipment object in the inspector of SketchUp Plugin. Was this object removed in the newer versions or I am missing something?

@Morteza it was removed. I tried adding it to the OSM file directly, but it didn't work (possibly an IDD issue). Perhaps @David Goldwasser can provide some insight into future plans, if any.

In the "Input Verification and Results Summary" report of the EnergyPlus tabular output there is a table called "Zone Summary". While not as detailed as what you get about lighting in the "Lighting Summary" Section, you can see electric power density by thermal zone. The table also includes lighting an occupancy density along with geometric and other information about the thermal zone.

You can also look under the "Energy Meters" report in the "Annual and Peak Values - Electricity" table. This provides consumption and peak load. It includes more than plug loads. If you are using OpenStudio 1.8.1 or later our default simulation report filters out just the plug load from this to create the "Plug Loads Summary" section. If you are using OpenStudio 1.7.5 or later you can download that measure from the BCL.

thanks David

is it possible have a table with annual consuption for a singular electric equipment?

sorry for my English .. is not well...

Hi @hal73. Your English gets your point across perfectly well so don't worry about it. However, this doesn't belong here as an answer. Extra info and responses to comments should be edited into your original question. Because of the way UnmetHours works, the thread doesn't stay in order (answers are usually ordered based on votes), and also you can only reply once so using it like an email chain or a regular forum doesn't work.

I think @MatthewSteen has a good answer. You may also be able to request output variables and set the frequency to run_period or annual. Below are a few of the Elec Equip. options.

  • Output:Variable,*,Electric Equipment Electric Power,hourly; !- Zone Average [W]
  • Output:Variable,*,Electric Equipment Radiant Heating Energy,hourly; !- Zone Sum [J]
  • Output:Variable,*,Electric Equipment Convective Heating Energy,hourly; !- Zone Sum [J]
  • Output:Variable,*,Electric Equipment Latent Gain Energy,hourly; !- Zone Sum [J]

@hal73 please edit your comment above to remove the image, it's too wide for the comment section and appears to be a duplicate of the one included in your original question.

Future answer EnergyPlus v8.4.0, Sept 2015, will have a new table report object to do just this. The Output:Table:Annual object provides a generic method of setting up tables of annual results with each row corresponding to an instance of an object.
