For example I would like to view hourly reports for pieces of equipment (i.e. chiller demand, chiller supply temperature, boiler heating output, etc.)
Once you know what you want out of an .rdd or .mdd file you can use one of the two measures below to add in variable or meter requests.
Add Output Variable
Add Meter
I should also point out that reporting measures can now add their own variable requests instead of having to add that request in a separate measure. It works by running a specific part of the measure prior to the EnergyPlus run to inject the variable request, then plotting or graphing that resulting data after the simulation. That process is described in the OpenStudio Measure WritingGuide.. I've linked specifically to the portion on reporting measures at the "energyPlusOutputRequests" method description.
Any plans to update these measures with a choice argument for all RDD or MDD options like in the IDF Editor?
@MatthewSteen, that is a good idea. If you had a generic .rdd or .mdd file in the measure resources folder this would be easy. The trick with is getting access to the last results from the arguments section of a model measure. @macumber may have ideas for this. One issue with this, when you know which variable you want, is that it would fail unless you had already run a simulation once.
Of course maybe a better approach is to make the "Output Variables" section more robust. It is already dynamic based on objects in your model, but it isn't comprehensive.
It should be possible to make a Model Measure that runs a single design day and outputs all the RDD and MDD options for a given model. We would like to improve the association of output variables with input model objects but that isn't on the immediate horizon.
I was envisioning the measure accessing the last MDD/RDD file to display only the relevant options to the current model and if unavailable displaying an empty drop-down like in the IDF Editor. Also, I think the list of available variables could be more user friendly if they were grouped in some way like the EP objects are grouped according to class.
