Attempting to model residential buildings in OpenStudio using the BEopt measures NREL has created, but am unable to run the measures. I need help understanding how to execute them. https://github.com/NREL/OpenStudio-BEopt

The working files have been downloaded from the website above and added to the OpenStudio directory. I followed the command prompt directions for running the measures as follows:

Running the Measures ... If interested in programatically driving the simulations, you will likely find it easiest to use the Command Line Interface approach. The Command Line Interface is a self-contained executable that can run an OpenStudio Workflow file, which defines a series of OpenStudio measures to apply. An example OpenStudio Workflow (create-model-example.osw) is provided with a pre-populated selection of residential measures and arguments. It can be modified as needed and then run like so:

openstudio.exe run -w create-model-example.osw

This will apply the measures to the OpenStudio seed model specified in the .osw, run the EnergyPlus simulation, and produce output.

I am attempting to use the "Workflow: Create Model" method image description

Upon executing, I get the following errors:

1) When I put the unzipped files from github in the "\openstudio-2.1.0\OpenStudio-BEopt-master" directory image description

2) When I take the unzipped folders out of the master directory from github and place them in the "\openstudio-2.1.0\" directory, I get a request for a Warning about a weather data file image description

3) Seeing the "ResidentialLocation" measure folder being referenced above, I placed TMY3 Weather Data (.epw) and design days data and (.ddy) in the "\openstudio-2.1.0\measures\ResidentialLocation", and get the following error image description

Any ideas on how to execute the BEopt to OpenStudio measures? I am struggling to figure it out.

Have you tried using them in PAT? That's probably the quickest way to generate a residential model.

Will give PAT a go by attempting to execute the measures as listed by the JSON code in the order it calls for... (https://github.com/NREL/OpenStudio-BE...)

That being said, any ideas as to my trouble regarding the command prompt approach?

To use the measures straight from the GitHub repo, you need to follow these steps: https://github.com/NREL/OpenStudio-BE...

Eventually the "official" measures will be posted on the BCL and it'll become easier.

EDIT: I changed the repo so you can more easily use the measures without going through the above steps. Pull the latest repo changes and it should now work for you.

Hi, I am interested to use this set of measures as well. I want to be able to run these measures from the OpenStudio interface / PAT interface. I followed the instructions and installed bundler and the devkit. But when I tried to run bundler ruby returns some errors. I want to make sure I am running bundler under the right directory. Am I supposed to run bundler under the directory with all the BEopt measures? or the whole "OpenStudio-Beopt-master" repo copied from github? How would that link to OpenStudio interface usage?

Also I tried pasting all the measures into my local measure library and access them directly in OpenStudio. Most of these measures appears to have a red icon flagged to it and says "cannot load such file". Is this the correct way to use these measures directly in OpenStudio? Or am I missing some steps. Thanks.

I tried both Ruby and PAT methods to no avail.

I was unable to execute some files in the GitHub repo folder as per (https://github.com/NREL/OpenStudio-BE...). 64-bit Ruby was successfully installed. On the Windows setup, I was able to get through steps 1-3. On Step 4 I ran into an error. I do not know which Gemfile I should be accessing. Should I be downloading a new Gemfile from here (https://github.com/NREL/OpenStudio/wi... And replacing the existing one? Do I need download the new Gemfile and place it in the c:\RubyDevKit\ directory? How am I supposed to access the Gemfile? And then what do I no next?

Being unsuccessful at that, I attempted to run it in PAT using these instructions (http://nrel.github.io/OpenStudio-user...), and no luck. See attached photos indicating the order the measures were placed, and the "completed Fail" error I ran into on the Run-tab. I am unsure why it is not running. What follows is the order I placed the PAT files in, and the associated Run-tab error.

Suggestions?

Did you see the Edit in my answer below?

If you want to go the bundler/PAT approach, you need to run "bundler" from the OpenStudio-BEopt directory.

Yes, I tried both methods. I could not get bundler to execute (maybe I am doing it wrong?), and PAT ran into an error. Not certain as to why.
