Thanks, though I wanted to know how to add a measure that I had downloaded externally. I figured it out eventually though. The measure and it's subfolders once downloaded, typically as a zip file to preserve the required file structure, should get unzipped and placed in the C:\Users\Username\OpenStudio\Measures folder. Once placed there, click the "Sync Project Measures with Library" button and OS will recognize the measure in the library and it can be dragged and dropped within the OS Measures table.

What you did will work, but it is much better if a measure is on BCL to download it from the application. This creates a local instance of BCL measures and components, that has a link back to the live BCL. There is a way to get updates if the author enhances or fixes anything in the measure. Using the application to download also protects the measure against accidental changes.

@David Goldwasser , Also, to change the units of OS result to SI, I need to run the measure of nico that is not in the BCL I am really curios the way of @SVVitale and I placed the unzipped file to C:\Users\Username\OpenStudio\Measures folder. But by clicking the "Sync Project Measures with Library" button, OS did not recognize and bring new measure to the measure tab? Wolud you please let me know how can I do it? Regards

Can you let me know if you solved this problem. Same here. Once i put some measure (ruby file and xml) under C:\Users\Username\OpenStudio\Measures folder, OS did not recognize and bring new measure to the measure tab. Tried restart, change measure folder, etc, and it doesn't work. Also how can we delete the existing measures that i already downloaded in OS? Where is folder for these measures downloaded from BCL? Thanks. I'm using v2.2.
