Hello guys, my name is Adityo. There is something happen to my Simulation on The OpenStudio Radiance. From my model, i want to do some simulation about Daylight. I make the simple model in sketchup and export the OSM file to run in the OpenStudio. For standar simulation (Only Radiance Measure), the simulation goes well. For further, i want the output of my model is more than graphic illumination. so, i install some BCL measure. (see the screenshot)

But after i add some measurement, the simulation doesnt run well as i expect. thereis no output file, CSV files. and also some error in the Log. (See the screenshot)

in this situation, i need my models can run the simulation and comes with CSV files as the output. So, the problem is in my Model (Sketchup) or the openstudio Radiance. I Need your opinion, because this is my first time use the OpenStudio Radiance, and using this as my tools for the thesis. And also, i dont know if thereis wrong to use the BCL measure in my model. (the step install ruby and the environment Path in Windows 10)

If you want see the model, and the Journal Log. you can download on this link

This is the part of the Log Process

Continuing Simulation at 12/07 for RUN PERIOD 1 Updating Shadowing Calculations, Start Date=12/27 Continuing Simulation at 12/27 for RUN PERIOD 1 Writing tabular output file results using HTML format. Computing Life Cycle Costs and Reporting Writing final SQL reports EnergyPlus Run Time=00hr 00min 6.06sec Script executing from: C:/Users/adityo dharmanto/AppData/Local/Temp/OpenStudio.n11696/resources/run/7-UserScript-0 Found argument 'meter_name' with value 'Electric'. Found argument 'reporting_frequency' with value 'Hourly'. Found UserScript ' ExportMetertoCSV'.

Thankyou you guys, hope you can helpme.

What output meter are you trying to get? There is a difference between Output:Meter and Output:Variable. You need to (1) make sure you are using the correct measure (meter vs. variable) and that you've included the AddOutputVariable or AddMeter measure with the same name.

Also make sure that whatever variables you select for the 'View Data' measure are added with the AddOutputVariable measure.
Another thing the .osm file does not include the measures along with it; these are included in the model folder of the same name. In order to see if you have the correct inputs to the measure scripts, you'll need to upload the model folder as well.

Sure this is my full folder of the model.

oh isee, my mistake is the different naming in the measure setting. thats why the output cannot exported well. thankyou

The OpenStudio Radiance measure should be the last one in your measure workflow. Add the meter first, then run the Radiance measure. The resulting idf and outputs should play nicely with your requested reporting measures, with the caveat that the Radiance graphical output is not easily accessed via reporting measure (the energy savings and new lighting schedules are, however).

oh i see, so the positioning placement measure effect to the workflow of the simulation? yes and i do the Replacement, and di simulation has no error but still some warning but its okay. Thankyou. Do you any recommend measure? i need a illuminance data, but no graphical. but in Data Excel. and also, its possible the openstudio Radiance can simulate Daylight in many Point, not only one glare illuminance? thanks alot

Yes, most measures can be placed in any order, since in general they are used together, to end up with a single input model. The Radiance measure is a little different, in that it's designed to be run on that final input model, the one that results from all the other measures being run. This is why it's important (but unfortunately not obvious) to place the Radiance measure last in the measure workflow. Glad to hear it's working for you now.

The Radiance measure does export the daylight illuminance (and glare) data to csv files; refer to the docs here for more info.

oh okay i see. So the radiance only export this daylightmetrics.csv - this file contains data for the following metrics for daylight simulation. Daylight Autonomy (DA) Continuous Daylight Autonomy (cDA) Useful Daylight Illuminance (UDI)

another that, isit possible the openstudio Radiance can simulate Daylight in many Point, not only one glare illuminance? thanks alot

oh ya, about the measure things before, why the schedule CSV files output there is no information what the unit data that used to?
